Can i solder an external wifi to this router?

Hello all This is my first post , just to say how wonderfull all these brilliant minds and cultures all rounded up with bright ideas working together for success!!Anyway here is my problem.... im trying to solder 2 antennas to the 2.4ghz (i think they are antenna 0 and 1, all the rest of antennas are AC so wifi 5ghz which i dont care)This router is a "Livebox next" Arcadyan VRV9510KWAC23 1-A-LTSo my question is .. Where to scratch off to put my Big horns XD?any other tweaks if possible to this kinda hardware like changing firmware etc would be helpful too...Thank you all for reading and have a good day.

USB WiFi Antenna Mod

I am working on adding a helical antenna to a cheap USB WiFi adapter.  My question is where do I connect the antenna to existing circuit.  I've attached a closeup picture with three likely points.  My three main questions are: 1) Where to connect the external antenna 2) Do I disconnect the rest of the onboard antenna (my gut says yes) or just add in the new 3) What impedance will the external antenna need to match?  I assume the components between points C&B; and B&A; are for some kind of impedance matching.

Wifi Router based radar?

I want to hack a wifi router somehow so that I can reprogram it to act as a radar. Emitting a signal for a microsecond and listening for returns and measuring their intensity. I dont know if the hardware in a router is fast enough for this or if it is possible to find an API or something to reprogram the router.

wifi receiver/repeater??

Hi everyone, i looked at the instructable of the wokfi antenna and the site of where it all started on that topic ( http://www.usbwifi.orcon.net.nz/ ).i found a free wifi access in my area, i got 1 pc (ethernet card+ usb wifi dongle), one laptop (wifi), a nintendo wii (wifi) and an old pc (233mhz, ethernet card) also a spare ethernet pci card and a pcmcia wifi not in the laptop, laying around .here's what i would like to do to have internet for free:- get the signal from the free wifi access point to the 233 mhz pc- use that pc as a firewall- then send the signal thru the ethernet cable and with another wifi (the pcmcia in the pc with a pcmcia to pci adapter or another usb wifi dongle, witch ever is cheaper) because my laptop can't reach the free wifi access point, it's to far..i'm looking for help on this please, i'll do an instructable with it because i think it could also be usefull to other. that whole idea of free wifi to anyone could be used here. because, let's say in a block, dorm, appartment a far away wifi connection could be shared localy. i've been digging for an intense 2 days now but my knowledge about networks and english (my first language is french) aren't that good so if anybody got an idea where to start looking it would be very appreciated.

Standalone WiFi booster?

 Hey guys, I was wondering if anyone knew of a project out there for boosting a WiFi signal.  I don't mean a parabola on the antenna of the router, I mean something that sits in another room, receives the signal, then boosts it and sends it out again.  Not sure how feasible this is, but I figured it was worth asking.  Also, I'm up for a bit of a soldering challenge :)

wifi issue

I PURCHASED MY MOTHER, who lives 200 ft from me, a DSL subscription to share. The phone company innstalles a WESTELL 327w router and I have a sony Vaio VGN-NW310F laptop.  Even though we had no clear line of sight, I still occaisionallyy got one and RARELY 2 bars.  The 1st thing I did was bought a Hawking HWUN3 wifi booster which plugs right into my USB. Great idea in theory, but it made no difference and was possibly even worse.  Plus, Hawkings Customer service is absolutely heinous, pitiful, and incompetant.  So I returned it. Funny...when i bought, it took 5 minutes for them to extract the money from my account, but 6 weeks to return it..but I digress. I then upgraded the antenna on her router with a LINKSYS HGA7S 7dba antenna which helps a little, which is to say I get 1 or 2 bars more relliably. I can get email but the signal is still too iffy to do much else. question is this:  I am willing to mount something outside and run a USB cable inside, or is there something INSIDE that will pick up/amplify or carry the signal to the laptop - either by means of a USB cable or not?  Also, is there software required? I am a disabled vet and this laptop is one of the few things I have, so I need help!  I'd prefer responses to my email, jb0579@yahoo.com  (and that's a zero after the 'b', not the letter 'o'. what can I do to get  a stronger AND more reliable signal?  As Ferris Bueller's teacher Ben Stein would say..."Anyone?.....Anyone?....." What's my best option here, folks?  Also, if there is a better place on this or any other site to post this, lemme know!!! Jim

RIFD / WIFI locator?

Does anyone know a system or how to construct an RFID / WIFI based locator system? I would think that an old dual antenna wireless G router could be used in combination with an RFID tag.  So when the tag is moved to a new location within range of the router the location will be saved or displayed on the computer screen.   I thought that having a system like this would be great for keys, animals, phones, babies, pills, etc.   Here is one example application: Where are my keys?  - open the web browser and retrieve the approximate location where the keys were last moved.  They are in between the sofa cushions.

Building a cantenna - choice of coaxial cables?

------------ My goal is to build a cantenna to receive WiFi signal, and transmit it via the coaxial cable to bypass a thick wall in my house, and broadcast it through an antenna in the destination room. ------------ For those who don't know what a cantenna is, take a look here: http://www.vias.org/wirelessnetw/wndw_06_08_04.html I read a few other tutorials like the one above, and the only thing I'm not sure is what kind of coaxial cable I should use. For example, I found this one on ebay: http://www.ebay.ca/itm/3M-6M-9M-Antenna-RP-SMA-Extension-Cable-for-Wi-Fi-Router-SMA-Coaxial-Adapter-/370811993692?pt=LH_DefaultDomain_0&var;&hash;=item56561dfe5c&_uhb=1 Would this RP-SMA type work for my application?  Also if I attach an antenna at the end of the coaxial cable, assume I have good impedance matching, how good would the signal be when I broadcast it in the room? Thanks for your response!

TV antennas and what is possible indoors

Back in my young years a TV antenna was on the roof, quite big and only required to get 3 or 4 channels at best.The basic design of these Yagi antennas has not really changed since then.Same for the antennas required to get UHF and VHF channels at the same time.They either comes as two seperate antennas with a mixer or as a UHF antenna with some added loops for UHF.To talk some basics:For UHF you can get away with quite small dimensions for your antenna bits.After all a quarter wavelengths here is only around 15cm long.With VHF though we get already 30 to 40cm here depending on the channels.So called bradband antennas claim to be able to get a wide range of frequencies.That however is only true for their dedicated frequency band.If you take a normal whip style antenna then this becomes obvious - just compare the lenghts required and you realise "going the middle way" will mean neither UHF nor VHF would get any usable reception.For a long time now there is the option of so called "fractal antennas" to get better TV reception....Fractal antenna? What the heck is that?The theories behind them are about as old as fractal antenna designs that were not even considered to be fractals.Let me explain with the example of a standard FM radio antenna.For them we use frequencies from about 88 to 108MHz.And of course, for our cars they are always on the roof or mounted somewhere around the wheel arches.Some cars however does not seem to have any antenna depsite having a working radio.In this special case rest ensured they do have one, usually behind the plastic bumper bar ;)I like to go off road every now and then and lost count how many times I had to replace my antenna after getting to close to some bushes and trees.As a solution I used some thin wire to create a L-style anteanna on the inside of my windscreen.And funny enough it picks up more stations than a "proper" antenna outside.Really old design and if you think about it then an antenna with a kink that looks like L is ""self similar" - the definition of a fractal ;)More complex shapes like the Sierpinski models do exactly the same just in one more dimension.Cell phones use them as well as you WiFi router that has no external antenna anymore.Their designs and looks are so different that it is next to impossible to list the currently used shapes here.What it comes down to, when you just take a very basic flat or wire shape is that the straight single segment of the active antenna is split into one or many shorter segments that change the angle.They all have similar relations to the wavelenght still.Means really long segments might be half of a wavelength while the shortest bits are just 1/64 of a wavelength.Think of it (far too simple of course) like amny matched antennas combined into a single one.With that often comes a destinct radiation pattern, usually with a quite narrow beam angle that provides a quite high gain.Are fractal antennas any better than for example a proper Yagi antenna?You can ask 100 people and you get 100 different opinions for this one.This is mostly due to some simple facts like:Not caring about actual comparisons.Not being accurate enough when building the fractal antenna.Using just very basic equippment to compare results.For example when you have a 30 year old and quite small TV antenna on your roof and struggle with digital TV reception than you might want to just replace it all.In some case even the old rabbit ears on your TV set will work better.But take modern Yagi antenna with 12 or more segments and even station that are 100 miles away have a good chance.Comes down to possible gain, frequency match and of course how well the antenna is aimed at the transmitter.Then why is it that some fractal antennas still seem to perform so much better?The big antenna scam....If you paid attention during the intial DVB-T rollout in your country then noticed two things.a) You were told you need a TV or set top box capable of receiving DVB-T signals.b) You need a suitable antenna.Well, A is obvious but for B a lot of people got scammed badly.You see, in almost all cases the frequencies allocated for TV signal did not change at all.And an antenna really does not care if the incoming signal is analog or digital - it only cares about the frequency.But more and more local stations often meant that the trnsmit power is limited.After all it makes no sense to have a 500kW transmitter if the area to cover is only about 20 square km big.So people were told they need new antennas once the noticed digital TV is more like playing Tetris, blocks everywhere....You analog TV had no problem with a slightly weak signal, you did not really notice it unless the weather was really bad as well.All the benefits of digital TV however only work with a proper signal strength.If your areas still has both analog and digital TV channels then have a look on how your local transmitter provides the signals ;)Part of the big scam was hiding a very simple fact:All analog TV is transmitted in a horizontal orientation while almost all digital TV is transmitted in a VERTICAL orientation.Ok, we already gain and ignored it but why would the orientation be important?Your radio antenna is vertical because the FM signal is transmitted the same way - the "waves" if you like go up and down like a sine wave.You still get reception if you turn the antenna 90° to make it a horizontal one but you will realise that weak station are no longer available.The same happened with digital TV.And if there is only digital TV left in your area then simple turning your antenna 90 on the mast to have the single elements vertical instead of horizontal gives you top reception again ;)If you struggle to get all station then just try it out before buying a new antenna ;)Modern fractal TV antennas come paper thin and often with rediculous claims in terms of gain and range.On Fleabuy you can even find models claiming to get stations from over 2000 miles away LOLSome even come with the fake claim of being omnidirectional, meaning it does not matter where you place them or how you orient them.A fractal antenna can't change basic phsyics though...High gain mean highly directional or at least with a very flat radiation pattern instead of being more like a sphere.A high bandwidth means you compromise on the gain and/or the phsical dimensions.For example a thin whip antenna is quite limited in the optimum bandwidth while a piece of tubing provides amuch higher bandwidth but at the expense of gain (and some other problems).A fractal antenna can compromise between the two worlds much better than anything straight.And you would even need to make the traces on the plastic extremely wide because you can simply add different lengths for different frequencies.Means a wideband fractal antenna for FM, VHF and UHF basically is three different antennas combined into a single one.It also means that there is usually always more than just one single element of the antenna that is receiving a signal.If you experimented with WiFi antennas for your router or modem than you certainly found the famous Pringles can antenna - highly directional and with an insane amount of gain.Works exactly like a simple directional microphone.And you could, at least in theory do the same with a TV antenna - if there wouldn't be the problem of the wavelenght.A pringles can works for WiFi because the wavelenght only requires an antenna of about 3cm in lenght.You might not want a row of steel drums with a diameter of around 80cm on your roof just to watch the news though...Ok, if I need a new antenna anyway then should I get a fractal antenna or not?I try to make it simple:Roof option not possible or too costly AND your transmitter is not too far away then try one of the cheap paper thin antennas you find online.If you already have an antenna on the roof that is suitable for the frequencies you need then check it to know if it is still any good.With age and weather comes corrosion and some antennas are connected badly in this regard.Sometimes you are lucky and all it takes is to cut off a few cm of cable to get back to clean copper and to give the terminals on the antenna a good fine sanding or a wire brush treatment.In other cases you might find an amplifier under the roof that has faulty power supply ;)And well, certain animals love to chew through your cable...If all is goo from antenna to TV then as said try to flip the antenna 90° to get it vertical.No, I did not mean to point it up to the sky..... ;)I mean rotate it around the x-axis if X is pointing in the direction of the transmitter...

Long Range Off the Grid WiFi Repeater

Hello Everyone,  I've got quite the project that I am undertaking and I am looking for a bit of advice. This will be my very 1st forray into long-distance wifi, as well as off-grid power resources, so Im biting off quite a bit at once! I have a friend who has been helping me with the research who has a much firmer understanding of both electricity and hardware, but he will be out of town for the next week and I would like to get a bit of progress on this while he is gone. SO, I shall consult the hive mind known as the internet. Alright, this project consists of creating an uplink between a remote shed, and a home in a nearby city, with a broadband connection. The rub, there is 10,000 ft mountain range in between the two. We have a site were we can put a repeater node at approx. 10,000 ft elevation, that has wonderful line-of-sight to both locations. However, this site is very remote, and will have to run off the grid obviously. The distances are as follows: Home to repeater: 3.96 miles (thats with Google Earth following the contours of the          mountain/valley, not sure how to make it just do a straight angled shot, so thats a rough estimate) Repeater to Remote shed: 2.68 miles (same issue) Background environment info: shed has generator + 60w solar array with 3-4 deep discharge lead RV batteries at 7400 feet. Has spring fed running water, which could be utilized for power as well, as obviously its always running. Repeater location is at 10k, as stated. Moderate to high winds very likely (data from peaks of similar altitude in the general area show gusts ranging from 40-60 mp/h, temperature ranges of  averaging 7 to 90+ for a the later part of July and August (F). Obviously, its very possible to get soemething below this, though the lowest Ive ever seen at the shed has been -15 (f), I would say most winters we could get a few nights that see temps below 0, but not often. Equipment Ideas: So to pull this off, we have come up with two ideas for the network equipment, which I shall discuss 1st, then I will show you what we have come up with for power.  - Network    - Repeater Node: rb433 wireless access point ($99.00) http://www.routerboard.com/pricelist.php?showProduct=43         with 2 r52h mini PCI wifi chips ($59.00 x2) http://www.routerboard.com/pricelist.php?showProduct=69         2 8-18 inch satelite dishs converted for long-range WIFI use (20.00 x2) http://www.engadget.com/2005/11/15/how-to-build-a-wifi-biquad-dish-antenna/ OR instead of a rb433, we could use 2 WRT54G Linksys routers like this. (I also have 2 BEF 801.11b routers that are legacy to the WRT54G. I would like to use this if possible! http://hackaday.com/2005/08/23/how-to-greyhat-wifi-repeater/ Now, I know that this later choice would increase power use by about double. From what I have been able to find, the WRT's would at anywhere from 4.2w to 8w of power. Anyways, I like this later choice because it would be significantly cheaper for the equipment, but do you have any other ideas? I know that the RB433 would work great, but its rather expensive all said and done after I throw up the power as well. Plus, if it takes a lighting strike, its out of commission, and 2 cheap linksys routers are much cheaper to replace! Anyways any input here would be great! - Power  so power to the repeater node is the real challenge. We crunched the numbers and came up with something almost exactly the same as below: From the datasheets, a routerboard will draw between 6-10W. So design for 10W. Over 24 hours you will need 10Wx24h = 240 Watt.Hours of power. For 7 days, you need 7x240Wh = 1680 Watt.Hours. A single, large deep cycle 110Ah 12V battery gives you about 1320 Watt.Hours of power, almost meeting the requirement. Now, to look at the solar panels: A good rule of thumb is to install 6 times the wattage that is drawn by the device. This is because only about 8 hours a day in sunny weather gives you maximum power output from a solar panel. So the other 16 hours you need to draw from the battery. (So already you need 3 times the wattage drawn by the device to break even each day) To generate 1 full day of extra battery power per sunny day, you need another 3 times the wattage. This is how we arrive at 6 times. 6 x 10W = 60W. So at a minimum I would recommend 60W of solar panels. That qoute comes from http://diywifilink.wordpress.com/ and http://mybroadband.co.za/vb/showthread.php?179547-Advice-needed-Setting-up-wifi-repeater-11km which is a project from a guy in South Africa almost exactly the same as the one that we are working on. The numbers came out to be about the same (Though they were a bit different when we calculated for the WRT54G option.) so, 60w of power generation to keep a decent charge on a battery. Now, we have a 60w panel at the shed, which is rather large to take up to 10,000 ft and place on the side of a mountain, and given the consistent wind element up there, we are hoping to do a hybrid system of both solar and wind. This is where things get tricky. A perfect balance, or even a more wind heavy balance would be great, such as 30-40w wind 20-30w solar. That keeps the panel size down, and uses a power source that runs 24/7. A Faroun Savonius wind turbine seems like the best system, but the controller to prevent overcharging etc is where I get nice and lost, having breached into very unknown territory. https://www.instructables.com/id/Faroun-Savonius-Wind-Turbine/ http://www.fieldlines.com/board/index.php/topic,129060.html This looked at 1st like a good, cheap system to use a controller board for the wind, but my question is would the controller board that comes with these solar panels (see below) work for both. That below is the setup that we use more or less at the shed, with some mods, such as a better alternator. http://www.costco.com/Browse/Product.aspx?Prodid=11298029&search;=solar&Mo;=5&cm;_re=1_en-_-Top_Left_Nav-_-Top_search⟨=en-US&Nr;=P_CatalogName:BC&Sp;=S&N;=4001192&whse;=BC&Dx;=mode+matchallpartial&Ntk;=Text_Search&Dr;=P_CatalogName:BC&Ne;=4000000&D;=solar&Ntt;=solar&No;=3&Ntx;=mode+matchallpartial&s;=1&topnav;=&Nty;=1&s;=1 So, can a small, 30-50w wind turbine and generator be built, with a small solar array to power this thing? I dont care if we have some down time, this is primarily going to be used as a system to get a weather station with web cam to send in hourly photos during the peak hours. I can have the system at the shed shutdown automatically  using some cron jobs in linux during the evening to conserve power. When there are people at the shed, we would like to be able to get a good enough wifi connection to use a wifi device (such as an android phone or ipod) to use as a voip phone in essential communication. The teenagers aren't going to be chatting with their friends for hours, but we would like to be able to put a short call through in case something goes wrong, or we just need to get ahold of someone at the shed or in the city. Next the equipment at the shed should be comparable to the repeater node,  sans 1 antenna and just some low power embedded system. We would like to get a webcam and weather station hooked up on this end, but that can wait for upgrades later if needed, if power doesnt allow it. like I said, a simple water turbine could be used (something similar to the wind turbine perhaps?) and even another wind turbine could be built to add extra power dedicated to running any system at the shed, though I dont think the wind is quite regular enough to be viable here, but if its cheap, we could throw it on anyways. equipment at the home in the city is simple, just use an extra laptop or desktop we have laying around to be server/router, hook up antenna to this, broadcast connection, run the weatherstation/webcam web server off of this. So, thats the plan, but load of input is needed to try to come up with this. We hope to try to keep this sub $1000.00, but the budget could go higher. This is DIY at its finest! Thanks in advance for you help!

This may not be the most appropriate place to ask such a question but....? Answered

 My Nintendo Wii, has an amazingly hard time playing online for some reason, I have done everything, I have added an older router as an access point to extend the range and everything (I am sure this part is done correctly, just so thats not all the suggestions I get), I have checked Nintendo's site tons of times for any help, which didn't help at all... Can anyone suggest anything that may help. I have been thinking about using of the 'ibles here about making an extender antenna. Suggestions greatly appreciated!! A little extra info on my wireless - I do have the second router set up to extend the range - The Wii says its getting full strength signal - I have used my Wii on other wireless networks with the same brand of routers (Belkin) and it works fine Thanks in advance.

Separate network for 5 Slaves 1 Master 1 server

I've build a home thermostats system with PIC18F27K42 in each thermostats with LCD, for 5 rooms, 1 master in kitchen and 1 server in the basement, working on a bit-bang i2c. The server only send data to i2c at every seconds as it have a RTC (Chronodot) plus freezer and external temp sensors. The kitchen has a bigger LCD and can send data to the server to send to a dedicated or all thermostats using an ID in the data stream. I have read some docs on the net and bought a ESP32 DevKit V4 with WROOM-32D (changing later for a WROOM-32U external antenna for the downstairs server) and 6 ESP8266 ESP-01S module to include in each thermostat. My goal is to use the wifi instead of the i2c. So I'd like to have some guiding on how to achieve this. Maybe later I may use this wifi to use internet to change some settings in one or all thermostats. But for now do I really need to use the house wifi or can I use a kind of "thermostats wifi", separate from the house one, mostly for heating security. If so, how can I do that, since I'm kind of new to network and wifi. Many thanks to all.

Wardrivers :/

Last night while collecting the mail, I noticed a glow coming from inside a car. The guy was sitting in the drivers seat with a laptop, and had a small antenna stuck on the roof of the car. He was running Ubuntu and was trying to connect into my wireless network. (WPA2 thankfully). I could even make out my SSID. I thought of knocking on the window, but I had a better idea. Went back inside and disconnected the modem from the router (just in case), and booted up a LiveCD of Puppy Linux. I created a ad-hoc wireless network as bait and waited. 5 minutes later someone was connected. The user connected was Darren-Lap. I got his IP address and managed to SSH into his laptop without any password prompts. Quick Google to see if I could send him any messages through the Terminal. Found a method and sent him a message saying if he didn't leave in 5 minutes there would be consequences. His reply: "F**K YOU! Suddenly the firewall was getting a lot of hits.  A simple "sudo rm -rf /" command sorted him out. (http://is.gd/fE7cL - demonstration) So here's a tip: Try to hack into my network, and be prepared to lose. :)

My network is really screwed up

I seem to be fighting a loosing battle with my network, things just never work like they're supposed to.For example, sometimes I have to reinstall my network printer on both my laptop and my ibook to get it to print again, even when the server has been running fine sans problems for a week, it will randomly do this shit.Another example is, right now I "was" just trying to copy some music over to an external firewire drive on my server that I have shared. I had the permissions on everyone set to full access yesturday but I noticed when I restarted my server, it did not detect my drive properly until I re-seated the firewire cable :S Thusly somehow it lost my share configuration for my music folder.I set it up, but this time I left it on read only because I wasn't planning on adding any music earlier, itunes and everything was working fine when i mounted the volume. I went on there and changed the permissions back to full access just 20 minutes ago as I wanted to add some music to my drive, I right clicked in my mac os x explorer and made a new folder just to see if I could copy over now, it worked, aswell as deleting the folder.So I drag the 60mb folder of mp3 files over, and it just sat there...and sat...and sat.... until eventually giving me an error -36, upon searching about, it means "-36 ioErr I/O error (bummers)".That's straight from the horse's mouth, and that really tells me nothing, what exactly does "bummers" mean???It's frustrating for me non stop, and it does this to me with other shares in mac os x, or they will randomly disconnect for no reason, sometimes after 15 minutes or sometimes after 3 days. I will note too, I can't connect to my server now, it just says missing alias in the mac os finder. Yet I can VNC into it no problem, wowa, but just upon checking my pc just now, it can't access any shares on it either, the cursour is just spinning, however I usually have no problems with my pc's accessing it, other than the printer thing.I'm just so god damned frustrated with my set up, I've looked it up and down until I was exhausted, several times, and I know I must be missing somewhere along the way, but I just can't understand how it doesn't work like I want it to. Shares are set up, firewire is out of the question, permissions set up, mac os x can log into server, check. It's all good until I actually go to use it for something when I really need it.I'll have to restart my server now to get it to work properly again...it was fine until I vnc'd into it to change the permissions, im gonna try restarting it now and just access it from it's own screen, perhaps vnc has something to do with it.Oh and to clear up any questions before they're asked, this is how I have it configured, as quickly and detailed as I can explain it:My network starts at my ADSL +2 4 port router/modem thingy (Speedtouch 546, it has it's own connection issues on the isp's side, but they don't seem impact LAN side data flow)That then gets split off to:*Port 1: iBook G4*Port 2: 25 ft. cable to 8 port switch (I'll explain that a little further down)*Port 3: 50 ft. cable to apple airport basestation in livingroom for wifi*Port 4: My main AMD PcMy ibook is configured for DHCP with manual address 192.168.1.64The switch just makes the modem think I have like 5 computers hooked into one port lol...My airport, for a long time I thought was perfectly fine as far as usuage with my thinkpad, however, I've been noticing the last few times it's powered on, the airport connects to the thinkpad, but assigns it a 169.xxx.xxx.xx address which does not exist on my network, but if I turn the wifi off and back on, it connects fine and assigns it a dynamic ip on my 192.168.1.xxx network.Other than that, I have it in bridge mode so that it acts pretty much the same as if the laptop were wired via ethernet, vnc, filetransfers, and online games all work good albeit the wireless delay, still not bad in VNC however.My AMD machine is set up for static ip at 192.168.1.66Switch:Port 2 of my modem goes to port 8 (uplink) of my switch.*Port 1: My server (Configured for static ip at 192.168.1.65)The rest are just my B&W; g3 setup for static ip at 192.168.1.68 and an old P2 I believe is at .69 and a 1.5 amd athlon aswell setup on 192.168.1.71, all of those in no particular order except I made sure my server stays on port 1.I did have everything setup so my server was on port 2 of my modem all by itself, but I needed the switch over by my server so I moved it, however, I was still having these problems before hand, even when my server was running on a completely different motherboard!Also, maybe could someone tell me why my server won't boot unless I have a bootable disk in the drive (IE: my windows 2003 server install disk), just so it goes to "press any key to boot cd.......", of course I don't push any key, and it continues to boot into windows.However, if I dare start my server without that disc in there, it simply goes to "Invalid System Disk error, insert correct/valid disk (can't remember it word for word), and push enter"I've tried reinstalling windows server 03, and same deal, yet it's using the same hard disk for the OS that my previous motherboard used and booted from not a problem.I really apologize for the long post... but I've quite literally burnt myself out and lost all motivation with continuing to expand my computer network and so I figured I would ask for help on here for one last resort, but I know many people probably won't read it due to the long post, but I have a lot of problems I don't have answers for and I need to explain myself somewhat thoroughly or else I won't find the proper solution for the problem, now will I?
