Laptop won't connect to my home wireless network, but other computers can. My laptop can connect to other networks tho..

I recently just moved back home from college and I can't use my wireless internet at my house. My laptop has always connected to every other WiFi signals and still does, just not my house signal. The problem is that it says it's connected with full strength, but it just doesn't load any websites or anything else that uses the internet. When I disconnect then reconnect, the internet briefly works for maybe 10 seconds then won't load pages. This is one of the strangest things I have ever seen because my Xbox, cell phone, and other laptop work perfectly fine on my internet. I even bought a brand new, very expensive router to try to solve the problem but that did nothing.

I am running Windows 7 and my antivirus program is Kaspersky, if that is any help.

I was using my home wifi connection(wap2 secured) to connect to internet through my laptop till last day, then it stopped all of a sudden. I can see all available networks including my home network but simply can't connect.After the password is typed for the home network, it will try to connect but can't connect.The only message i get is that "your computer can't connect to any of the prefered networks".My operating system is XP S3.What shall I do to get connected?

Try this 1

1) First make sure that your wireless connection is not disabled.

Click on Start --> In search box, type ncpa.cpl and press Enter

"Network Connections" window will be opened. If you find your wireless

connection icon in grey color then right-click on it and select "Enable".

2) Check your SSID and the security key.

Good Luck

I am able to see wireless network in my laptop and after clicking on connect button, pop-up for password came.

But after that nothing happens.... I am not able to connect to wireless network. This problem persists since 1 year , please help.

start a new question about it. Only people following this question will see it since it was asked a while ago.

if your browser is mozilla firefox, go to the top left hand corner and click the yellow tab with firefox inscribed on it. click options, then on the sub menu click options again. a window comes out, then go to advanced at the top right hand corner. just the next line under, click network. under connections click settings. in the new window that opens, select no proxy and then reconnect to ur home wifi, see if it works. if not try the other options. one will surely work.

My aunt called me about her laptop having connectivity issues. I go over and do the usual checks. The computer has it's own IP (not static) and it can ping to the router, the loop back address, and any other computer on the network. It will not connect to the internet (yellow icon on the wireless icon). It can connect hard wired, but no wireless connections.

I asked her about updates and she can't recall doing any. I have uninstalled and re-installed the drivers for her wireless NIC. It connects to the network, but says it cannot get internet access. I tried the nslookup and it times out and the tracert says it is unable to resolve target system name. I used for both of these. When I do the windows connections diagnose tool, it says the connection is broken. I'm at a loss as to why it works. Her computer will connect to other connections, but not at home.

Hey, can someone please help me? I have this problem and its really frustrating.
My problem is..When I connect to the internet it usually says I have internet connection but Google Chrome says "The web page cant be loaded" and after a few minutes my internet connection goes down and says I have no internet access. So I reconnect to the internet and the same thing happens, I repeat the process and a few times it works but only for a few minutes and then it happens again. (The internet works perfectly fine on other laptops and phones but its just mine for some reason).

I asked this on another site and someone told me to go to "My Computer" and then right click it, then go manage, then to click on "Device Manager" and then click on "Network Adapters" and to double click on each of the Intel (R) things there. Then to click on the power manager tab and untick the box that is ticked.

I have also done this:
1. Click Start, go to control panel.
2. Click Network and Internet.
3. Click Networking and Sharing Center.
4. Click Change adapter settings
5. Find your wireless adapter, right click it, and click Properties.
6. Scroll down to Internet Protocol Version 4 (TCP/IPv4), and double click it.
7. Click the radio button that says "Use the following DNS server addresses:"
8. Put for the Preferred DNS server, and for the Alternate DNS server.
9. Click OK and test your internet.

Can anyone please help me?
I have a really weird problem. On my laptop I connected to a network, but it says No Internet Access. I went on a different laptop, connected to the same network, and I was just fine. Can someone tell me what's happening?? Im on Windows 8 btw
You should make this a new question, you will get a better response that way. I am subscribed to this question so I got a notification that you made a comment, otherwise I would have never known. Most of us follow the newly posted questions but not so much the comments on older ones.
Ambo5494 years ago
Having very similar issues here myself. I read everything in the Tutorial and followed every step to no avail. So here's my problem, my old computer connects to my internet just fine, my new laptop however gets the yellow caution symbol/No Internet access/Limited Access. Every once in awhile the yellow flag will disappear and it says Connected but I can't actually open any pages.

When I run ipconfig /all it shows that my DHCP is Enabled, Subnet is, Gateway is and IPv4 Address is

When I check my working computer the IP address ends in the hundreds so I don't think there's an issue there. On my non working laptop I changed the DNS server to Google's, I even tinkered with the IP Address, only changing the last digits. Still nothing worked even after restarts and tinkering with those settings multiple times before finally deciding to just go back to obtaining address' automatically.

Also did all the default stuff, reset modem, used Windows Troubleshoot (I'm on Windows 7 btw, if that matters - the computer that does work with my internet is my old Dell running XP). I even removed my antivirus software after running it one last time. I figure I can redownload once I get this network issue resolved. Also ran MalwareBytes. Nothing was picked up. My laptop will connect to open connections, it just doesn't seem to want to connect to mine. I do have it secured WPA2 - Personal. AES Encrypted.

Any help would be greatly appreciated. Thanks

Have you fixed the problem?

If not, I will go into the ipconfig command a little further. Please type:
and then press enter.

Then find your WLAN Nic connection, and you should see something like this:
Connection-specific DNS Suffix : (something here)
Link-local IPv6 address: fe80::948c:XXXX:XXXX:XXXXXXX
IPv4 address : 192.168.X.X
Subnet Mask: (This is probably the exact mask that you will see)
Default Gateway: 192.168.X.X

Please tell me the IPv4 address, the subnet mask, and the default gateway.
Can u help me please... I have the same problem, Internet will connect to all other computers, phones and pcs but not one lap top. My ipv4 is 1.102 at the end, subnet is the same, gate way ends in 1.254
Please help x
Sure. Let me just get some background to make sure you have the exact same problem.

1. Does your laptop work ok on other wifi networks (coffee shop, library, etc.)?
2. Did your laptop work before and just stopped working recently, or has it never worked on this wifi?
3. What system are you running, and what (if any) antivirus are you using (and did you switch recently?)
4. Can you run an ipconfig /all and tell me what your DNS servers are?

The ip address you listed is a valid address in the correct subnet, which means that you are connected to the network, but something is blocking you from getting to the Internet. Also, please tell me what brand of router you are using. (I'm guessing it is 2-wire... Right?)
1.I haven't actually tried on other networks. I live in the middle of nowhere with no coffee shops etc around. Does this matter?
2. maybe I should let you know exactly what happened... Basically I live in a pub, we have 2 routers and an extension. Let's call the downstairs one x and upstairs y and then the extension would be called y ext. I was connected to y when it stopped working. I turned it off at the wall thinking it would reset it. When I turned it back on and searched for the network it had changed name, instead of y and y extension I now have pheenet and pheenet ext. So the answer to your question... It has worked on this network before but it was called something different.
3.I'm not 100%sure but I believe I am running windows 7 and I have avast security. I haven't changed recently.
4. I think I have done this right. My dns servers say
I'm guessing th router is made by pheenet

Thanks in advance x
1. No, but if you were able to test it on other networks, it would rule out a few possible problems.
2. That does help me, thanks.
3. Great, you can also be sure about what system you are running by pressing the windows key and pause/break key together, that will bring up the system properties window so that you can see all your system information. :)
4. I think we will change those DNS servers... I don't like using a broadcast address for DNS servers. :)

So lets try setting the DNS servers to Google's free DNS servers.
1. Click Start, go to control panel.
2. Click Network and Internet.
3. Click Networking and Sharing Center.
4. Click Change adapter settings
5. Find your wireless adapter, right click it, and click Properties.
6. Scroll down to Internet Protocol Version 4 (TCP/IPv4), and double click it.
7. Click the radio button that says "Use the following DNS server addresses:"
8. Put for the Preferred DNS server, and for the Alternate DNS server.
9. Click OK and test your internet.

Let me know what happens with that... also, if your network was secured before and it isn't now, I would suggest securing it. In a browser, type, hit enter, and it should give you access to your router settings. You should also be able to change the SSIDs to whatever you want to call it. :)
kgio1 thegeeke5 years ago
thank you so much it works used to work then stopped so had to use ethernet but now my wifi works
thegeeke kgio15 years ago
Great! Glad to hear it helped! :)
sorry, to told U that your solving steps doesn't work let me told u the some different about my problem
- My laptop can't see my home's router network by wireless into the available wireless list although it can access the network by direct cable.
- Any other devise can access it by wireless property smoothly without the need to the cable.
- And The very strange thing Is that my laptop can access my neighbor network by the wireless property !!!
- Ip =
- gateway =
- sub-net mask =
- My laptop accessed it for many times before this problem appears so,I think it is some thing like windows filter options about this network !!
- wish U help me,,,
Thank you @thegeeke
OK, what system are you running? Also, have you upgraded any hardware lately? (Specifically your wireless router)
@thegeeke please help. I've read through all your comments and still can't get a wifi connection. We got a new modem box And the laptop won't connect. Phone and iPad are both connecting. Please tell me hat I need to do! Thanks
OK, on the new router, does it have a wireless "letter"? (A, B, G, N) Also, how old is your laptop? If the wireless NIC in the laptop isn't compatible with your new router, you may need to get a new NIC. (Very cheap on Amazon... it's just a USB adapter so no complicated installation is necessary.)

Also, did you happen to read my two instructables?

They might be able to help you with the basics. If none of this helps, can you give me some more detail about how the computer isn't connecting? Does it see the network in the network connection list? Does it give an error message when trying to connect? Can you use it on a wired connection to the router? Is it able to connect to the network but just not the internet? This type of information can help me diagnose your problem. :)
I've also been having problems connecting to my home Wi-Fi. I just took it to a computer repair and it connected to their Wi-Fi. My computer can sense my home Wi-Fi, But it won't connect to it. I have a Toshiba satellite P845-S4200 That runs on Windows 7. Do you have any possible solutions that could help me connect to my Wi-Fi? I can provide you with any information that you need.
Do you get an error message when you try to connect? If so, what is the error message?
Hi, my laptop won't connect to my home wifi. I've tried the troubleshoot but it's not helping. my phone, ps3, etc. can all connet to my wifi but my laptop cannot. When I launched the troubleshooter it said the problem was that it needed to be connected to the ethernet cable. When I do, it allows my laptop to connect to the internet, but it means that my phone, ps3, etc. cannot. I'm not sure why it won't connect, i've reset the laptop several times now but it still won't work. It hasn't connected for about 2 months now, and I was wondering if you knew how to fix this ploblem.
Thanks heaps!
Can you post your IPv4 address, subnet mask, default gateway, and DNS servers?

Also, these instructables might help you:
I have an annoying problem now too. I just recently had my laptops screen replaced. It has been left with the power off for 13 days now and it worked fine until then. Now that I have had it repaired (not sure if the laptop is just being screwy or the technicians did something) the wifi isn't working properly. It keeps going between being connected to my network, but no Internet and disconnecting itself and then not being able to reconnect.

As with everyone else on this post though, my other devices are connected and working properly. I have tried resetting my adapter and the modem, neither helped. Nor did restarting my computer.

When the wifi is connected it shows full bars and the dhcp is enabled... The DNS is and the subnet mask says I also tried the part. Nothing worked.
Now the problem is that it can't even connect to my wifi.
It sounds like when they replaced your screen they might have accidently bumped the wireless antenna (it is very fragile and depending on the laptop design it can be very close to the screen). I would bring it back to the repair shop and have them fix it... if they are reputable they should fix it for you. :)
I tried that, but it connected and worked there. I just tried uninstalling my antivirus program and the only thing that changed is that it is letting me connect to the wifi, but it doesn't not load any pages, nor download any updates.
Could it be a virus?
It's possible, but I really think it is more of a loose connection. You could try downloading Malwarebytes and running a scan with that, but my gut is telling me it's a loose connection; which would cause intermittent problems.
What do you mean by loose connection? Because the wifi worked when I was at the computer store. It went at a normal speed. Is it easy to fix?
There is an actual antenna inside the computer itself. It is very close to the screen in some laptop designs, and it is a very fragile piece of wire. It's very easy to accidentally bump it when working on a screen (I've done it myself), and it can loosen the connection. If that connection is loosened, it could A. Cause the WiFi to stop working altogether, or B. Cause intermittent problems that will get worse over time as the wire is wiggling back and forth as you move the laptop around. Speed probably wouldn't be affected when it works, it would be all or nothing.

Fixing it could be as easy as opening up the computer and pushing it firmly back into the connection, or soldering it back in place. If that doesn't work, it's an easy fix to replace it... any computer shop that can replace a screen should be able to do it. Like I said, it's so close to the screen that it seems like too much of a coincidence that you just replaced your screen to not be related. If they are a reputable company, they should have no problem with checking it out for you, and fixing it if it was their fault. :)
I have a Toshiba p755 s5320. Do you know where if there is a video on how to get to the antenna on there? If I can I would like to try just fixing it rather than having to drive back to the computer store.
Surprisingly, there isn't a lot out there about how to do this... the closest I was able to find was this:
fter researching your laptop, I was able to confirm that the antenna is actually in the lid (not necessarily in the LCD, but in the casing around it).
I think the hardest part will be finding it, after that it should be pretty easy to trace the cables and make sure there aren't any problems with them.  :)

Your other option would be to get an external wireless NIC that plugs into the USB, but this can also be kind of a pain since it ties up one of your USB ports.
Well, they looked at the antenna but physically it looked fine. If I wanted them to do a diagnostics test on it, then I would be charged. Any idea how to run one myself?
Hmm... I'm not really sure what diagnostics could be run on it short of physically feeling the wire to be sure it wasn't damaged and wasn't pulled out of the socket. When the WiFi will not connect it doesn't even see the network... right?
It does see the network. For some reason it seems to be working better
After being connected by Ethernet.
Hmm... so it will just not connect to the network when it does see it... right? Does it give a specific error message or code? If it is able to connect to the network but not the internet, run an ipconfig /all command from command prompt and tell me what it says.
It just says "sorry network not available at this time". However, I am in more of a pickle now. For some reason my computer started just turning itself off completely and now it seems to have shorted out and I smell smoke. I do not believe it was the people who repaired the screen though. I was dealing with this before then. For some reason whenever pressure was applied along the central portion it would just turn off.
It's possible that you have a short in the motherboard, which would cause quite a few problems... and could account for everything you are saying. If you can open up the computer and see the short (or anything on the motherboard that shouldn't be there), and it is an easy fix, that would be my only solution at this point... what you are describing does sound like a short, and probably somewhere shortly after where the power comes into the computer.

If it comes to replacing the motherboard (especially on a laptop) you are better off just replacing the computer. :(
Well, both my more computer literate friend and I looked inside and could not find anything that looked burnt. When I press the power button the light comes on. However, the screen does not show anything, so we tried running it to an external screen and still nothing showed up. It also charges the battery when plugged in.
You can't always see a burn near a short... and it isn't always that obvious where the short is. The fact that the screen doesn't show anything just reinforces the theory of a short on the motherboard.

When you power it up, do you hear the hard drive spinning, or do you just see the power light? How about fans?
I figured it is. Anyway, when I turn it on all that happens is the fan spins for a few seconds, then shuts off. After that nothing happens except the lights.
Defiantly sounds like a short... I would replace the laptop. :(
What do you think of this service?

Is it possible?
I don't see how he could even pay for the hardware for $165... maybe $165 for labor... which seems a little cheap... but possible. If you do decide to go with that service, make sure you get a clear contract in writing in case you need to use it in court. Also make sure he at least has a CompTIA A+... anyone working on hardware should have at least that cert.
Will do thanks.
i am having the same problem and it works at coffee shops and stuff and at my house most of the time but at my sisters my phone will connect but my laptop will not
Hi. I am having a similar problem and came across your posts. All other devices connect to our wireless network - other laptops, iPad, printer, etc. - except mine and only recently has it stopped working. Went away on vacation with it turned completely off and came back to a spotty connection and no nothing. I have updated my driver, and I have taken it to a place with WiFi and I connect without a problem.

I followed your instructions above and do not have anything in the "Connection-specific DNS suffix" line.

I do not have the 948c in the IPv6 line - it has 3c31 instead, don't know if that matters.

Next, my local IPv4 address has which one of your posts below would seem to indicate a problem as you mentioned that as long as it didn't start with a 169, the person should be okay.

My subnet mask is and there is nothing on the default gateway line.

Am I completely in trouble, or would you have any suggestions on how to fix?

Thank you so much for your help!!!!
OK, that is telling me that it is not receiving a IP address from DHCP. On another computer that can connect to it, please run the ipconfig command and tell me the IPv4 address, default gateway, and if the subnet mask is different from (which I highly doubt) tell me that as well.

We can manually assign a static IP address for your home network (which should in theory also make the network more reliable assuming that's the problem with the spotty connection), however; you might need to set it back to DHCP for other networks. (I'll give you all the information once I know the IP address.)

Also please tell me the brand of your router and how many devices are connected to it so that I can estimate what IP address will be available. :)

(And wow... this post is getting very popular... I'm even getting PMs from it!) ;)
Thank you so much for the prompt response. After I thought more about your post to someone else about the 169 IP address, I decided to dig into that more. So I ended up resetting my router, not just unplugging it, and then restarted my computer once it was finished. And well, well, well, back to a normal IP address and the correct subnet mask (I did not have the last 255 in the third position before). The only problem I noticed was that I still needed to tell the computer to connect to the network and that seemed to take a long time So I then removed the network from my list of networks and then added it back, and it has now connected automatically and the whole Internet connection seems much faster as well.

So far, so good. It has gone to sleep once and I did not lose connectivity. The true test will be what happens overnight when it's in sleep mode for a longer time. At that point, you may hear from me again!

But for now, I think I have solved the issue by resetting the router entirely. All other devices still work fine and I'm back on-line!

Thanks again for getting back to me and for your willingness to help! I greatly appreciate it!
No problem. There may be a setting in the router for keep alive, which you can set the router to reboot at a certain time each day. If you need to use it, more than likely the router is going bad, but it keeps it going for awhile longer without you having to remember to reset it each day. ;)

(You can access the router settings by typing the IP address for your default gateway output from the ipconfig command into a browser. Default usernames and passwords should be listed some place on the router.)

So here's my issue. It appears to be a bit different from other problems here.

Home network, secured with WPA2-Personal. It's been in place for a good while. My laptop connects to it fine, as do our cell phones and tablets.

My wife's laptop now fails to connect to the home network at all, but it will connect to public networks (as well as our neighbor's unsecured home network). This shows that the modem is working and that the issue is limited to how her laptop connects to our network.

While attempting to connect to it I ran the PROSet Wireless Manual Disgnostics, and it showed a failure at the authentication process. I then got green across the board when successfully connecting to the neighbor's network.

I'm curious as to what little thing I may be missing.

I've tried ipconfig /flushdns to no effect, likewise /release and /renew.

I've tried deleting the home network from the list of detected networks and re-inputting the security parameters for it, but that didn't work either.

I changed the name of the laptop, in hopes that the network might treat it differently. While I had to supply security credentials again, it still failed.

Current Network Diagnostics results suggest router or access point issues. I've unplugged and restarted both the router and the modem, but haven't hard-reset either at this point.

I'm at the point where I need more minds looking at the problem who can suggest things I haven't tried yet.

The laptop in question is a Dell Inspiron 5520 running Win7 Home Premium, 64-bit.
You should ask this as a new question rather than tacking it onto an old question. The only reason I noticed it is that I was following this question from long ago.
Anyway, something to try for you is to remove the WPA2. Go with an open unsecured network and then try and connect to it. If it does connect then you know you have a problem the the notebook wireless card. Possibly the WPA protocol is corrupted and it cannot translate the scrambled secure info. I have had a problem with security protocols and routers and NIC's not working together. I usually just change to WEP or get a different wireless adapter.
When you change from the WPA2 remember to write down all the settings so you can turn it all back on after your test.

This has been a headache for almost a year. And when I Google my problem, there are so many different answers as to what to do to solve it....which makes me unsure. Oftentimes I troubleshoot and loose total connectivity and have to search online on my slow "not-so-smart-phone" to fix what I just made worse. Ok we'll start from the beginning.
Asus netbook running XP Home (french version)
Ethernet works
WiFi works at McDonald's (yes we have those too in France) and I can connect at hotels and other WiFi hot-spots.
My Streamium Internet Radio connects to Wifi just fine and so does my daughter's Nintendo 3DS.
Netbook used to connect to wifi at home but just magically stopped. Actually, it does connect! Excellent strength, sends and receives packets but internet pages will not load. (Cannot be found Check DNS error) If I replug in the Ethernet cable, I can then open internet pages. Also, even with Ethernet cable connection, if I put my netbook in sleep mode, I will have to reboot in order for webpages to work again.

I've tried to follow the other users examples/advice but not sure if the instructions refer to my case 100%.
This is what I have.

I'm not computer illiterate but also afraid to lose what little connection I have! (And yes, I have screwed it up bad before following bad advice...) I feel that here I may get a good answer. Just really tired of having a netbook that does not function as one!

Thanks ahead for any help. And be nice on me...I know the question has been studied and answered many times over.

I can provide pics if needed.

Someone please help me!
I am writing this from my friend's computer. He can connect to my wireless network, but i can't.
I am running windows 7 ultimate, and so is he.
We have a dlink router, and one day i came back home, i couldn't connect. At all. The network just wasn't there, in my list.
I have tried to connect to a wireless that is in this building, that has no password or encryption of any sorts, and the computer tries to connect for a few seconds, then just says screw it and brings up a menu that says, troubleshoot (which i have tried and it doesn't work) and more about internet connection problems ( which tells me i don't have an internet connection, which i need. I tried plugging the cable directly into my comp, but then it says unidentified network, and i can't connect.
While connected like that, i checked my subnet mask and it is and my friend's is I don't know how to check any of the other things.
Also, I have had this problem before, but before i called the handyman to fix it, it magically started working.

Please help, my job is depending on it.
I'm sorry I didn't see this post until just now. My guess is that when you look at your IP address, it starts with 169.254. Right? What IP address is your friend's computer showing? Try taking the last number on his IP address, and add or subtract 25 from it. Your number that you chose should not be less than 0, or grater than 254. So for instance, if your friend's IP address were, add 25 to that so that you get If it were, it does not matter whether you add or subtract. (25 is not a magic number, it's just my best guess to avoid addressing conflicts.) Then assign a static address using that IP address that you just figured, the same subnet mask as your friend, and the same default gateway. Use DNS servers and

Instructions on how to do this in step 6 here:

Then try to connect to your network. If this works, that means there is a problem with DHCP. Since a friend's computer works OK, and yours doesn't, and also you can't connect to another network, I'm guessing the problem is on your end. This can be caused by a number of things, mostly by viruses. Run a virus scan with your antivirus program (I assume you have a up-to-date antivirus program... right? Not Norton or McAfee... those do not count as antivirus programs... they screw up your computer almost as bad as the viruses do!) Another possibility is that your wireless NIC (network interface card) has gone bad. You can pick one off of Amazon pretty cheap.

Let me know if you need any more help. :)

Have you tried renewing your ip address through the command prompt's ipconfig command? You'll have to look up the exact syntax.
Other things to try: delete the network out of the list of configured networks and reconnect manually, reset the router and modem, if you have cable. Make sure your browser didn't somehow end up in offline mode.

I have tried resetting the router and modem but that did not work. My browser is not in offline mode because I can connect perfectly fine when I use an Ethernet cable.

Can you explain a little further how I go about renewing my ip address through the command prompt? I have no idea how to look up the exact syntax or what that even means lol. Are you sure that would be the problem though? My reason for asking is that I can perfectly connect to any other network.
helps to disable other networks first; ethernet, bluetooth, etc.
start>searchbar: 'network connections'

start> run/type in the run commandline:


type ipconfig /release
type ipconfig /flushdns
type ipconfig /renew

then typing ipconfig /all
should show your main wifi connection and its ip address... I won't go into explaining the long as you don't have a 169.x.x.x address you should be okay.

other options;
in your network connections box,
right click wifi, 'repair'. others suggest, reinstalling tcpip might help - but since ethernet works makes me think nothing wrong there.
Here I am in the same boat....
Not able to finish matters
Please explain me how to fix it as I got the 169 problem on my acer laptop but the one by the side which is my friend's works fine. just trying rest of the things what u have said till i get ur exact advice. hope u can do it. thanks in advance.
in addition it is like ipv4 ----
subnet mask--------------
what else should i tell u?
a 169 address means the wifi could not be configured through dhcp and is getting a generic 'failed' address. Did you perform the above instructions?
yes and also did this ipconfig stuff......the ipconfig/renew said it failed...but i am sure i still got the 169 on my ipv4...could i try ant thing else as I already did the small part manually by making and and it indicates.....?
If renew failed, then you're not connected to the network -- or it's configured wrong.
so where should i start from again from?
It could be a lot of things. When you go to connect to a network, and windows asks for the password, what happens after you type it in?
Hey Thanks buddy I am done with those......I think I did something with ping and found the gateway numbers which were not showing before.
But i hope I won't be left out of internet when my friend goes away out with his laptop i guess. because normally it use to ask for a password. It did for my friend too this morning. The Free Wifi. It did for my friends laptop too this morning but for me it was not even asking any of those. I doubt whether I am connected only because of my friend. let me try more options and catch u back.
Any how thanks......
yes i think i did click disconnect as I saw nothing happened for a while and thought i am doing something on the wrong direction. so where shall i start? something from managing wireless.....?
frollard covered ipconfig below.

To remove the network:

Open network and sharing center
Click Manage Wireless Networks on the right side bar.
Select your home network and click remove.
Click Add and select Manually connect to a wireless network
Enter the relevant information. Have whoever setup the network make sure all the information is correct.

Check your DNS settings. There are maleware programs that will redirect the DNS to a different and often malicious site. When the antivirus detects that it is going to the wrong places it disables the connection to prevent you from accessing problem web addresses. Even if the program gets removed it often leaves the DNS wrong. Most of the time DNS is set to automatic. This means that it gets the DNS settings from the gateway which is usually your router or the ISP router. You can manually set your DNS to a special HighSpeed public DNS service. Using these numbers you always know that your DNS is getting the corect numbers and is not redirected. Also its usually faster in looking up sites.

Here is an article about it including the public DNS numbers.
