Linksys WRT120N Un-boxing

It was time I replaced my aging (and case-less) Belkin 54G+ router with a newer one, I've been having lots of problems with disconnects lately, and also with computers on my network not identifying correctly under my DHCP client list. Although I thought it was just one of my computers fudging up my network somehow, after replacing the router, all the computers seem to show up properly, although I still haven't powered up my server yet, but that's another story... I'm not holding my breath, but this new linksys router seems to be a great improvement over the belkin. Not only that, the linksys has a Plethora of options compared to the belkin, everything from some rather advanced wireless settings, to bandwith and QoS management (basically I can set higher priority to one computer on my network, than the rest of them). A lot of features in here that not most people will use, but I will now get the chance to monkey around with. Anyways, I always get thinking, after I unwrap a new toy and play around with it, how I wished I had taken pictures while it was still in packaging and whatnot. So this time I finally did. I also did a bit more cable management and mounted everything on the wall behind my door. The wires could be neater but it's much better than it was and gives me some more space on my server rack!

How would you remove the two antennaes from a Linksys WRT 54G Router. Can range extending antennae then be added.

Our router has some limits on its range. I know on some similar products, the aerials can be unscrewed and then replaced with range extending antennae. Can this be done on this Linksys router and if so, are there suitable antennae that would do the job and so enhance its range.

How to uninstall and reinstall a network adapter? Answered

My title is a simplified version of my problem. I accidentally clicked uninstall instead of disable on my wireless network adapter. I don't have the CD to install it. My WLAN adapter is a Cisco Linksys WUSB54GC Wireless Network Adapter version 3. I've uninstalled the device multiple times but when I reinstall it, it simply says 'The name is already in use or a service display name' and then when I go back to device manager it says the name of the adapter and then a #14 and the next time I attempt to reinstall it, it says #15 then #16 and so on. What I am doing is I'm going to device manager, updating the driver software for my adapter, then clicking 'Let me pick from a list of drivers on my computer' and then clicking 'Have Disk' and choosing the netr system information file. After that, that's when it gives me the name is already in use or a service display name error. I've reset my computer a couple times, searched bing and google a lot and got similar problems but none specific to my situation. Please help, I don't recall trying to install or uninstall in any certain order so my mess there could have corrupted something, maybe. Thanks!

For some reason my laptop will only connect to an unsecure linksys network and not my own personal, secured network despite entering the network key and the fact that other devices connect to it seamlessly.  It simply always defaults to this unsecure network.   I've already removed and added my home network as an attempt to troubleshoot the issue, but still no luck.  The laptop simply always reverts back to the unsecure network.  My home network has more bars and is listed on the top of the list for preferred networks.   The laptop in question is at least 6yrs old.  Runs on WindowsXP.  Is a Sony.   Is there something I should do with the drivers or how it is configured.

Home Security (take two) Windows or Ubuntu? Server or Desktop?

I've had a little experience with the security system setup from my last post, but I moved, and I'm going to try something different. Should I use Ubuntu Desktop or Ubuntu Server for webcam monitoring? I'm a Windows user who would like to eventually learn how to use Linux as well as i can use Windows. But in the meantime, I'm about to set up webcam monitoring in my house. I've got a few USB webcams, and one LinkSys wireless webcam. I'll obtain the monitoring software from a third party. I need an operating system that can handle processing four video streams as well as running the security software. (I'm also going to use remote admin software so that I can have a "headless" setup.) I'm currently running WinXP Pro (Corporate) on a machine with an A.M.D. Athlon rated at 1.02 Ghz with 2GB RAM. A friend of mine recommended that I use Ubuntu Linux, which I think is a great idea. The problem is that I don't know if I should use the Desktop or Server edition of Ubuntu. Also, since the rest of my network (and family members) uses Windows, the remote admin software I use either has to be cross-platform, or be Linux compatible with a web-interface. So should I use Ubuntu Server or Ubuntu Desktop? Or should I stick with Windows? Also, as far as the webcam security software is concerned, I need software that handles multiple streams and has options for motion detection, record on event, notification through email, and a web interface (HTTP server). Also, FTP options would be nice to have, but are not required. Any suggestions for this? (Win?/*nix)

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

Home Security

I'm planning on setting up a simple home security system for my home. I was thinking of using Wireless IP webcams, placed in strategic locations, monitored by software with a motion sensing function. I would tweak the sensitivity and add null zones as needed. I would probably only use two or three cameras to start out, and have the software save ten or twenty seconds of video when the motion sensor was triggered. EASY. Once I have the motion sensing bugs worked out, I'd like for the software to email/text message me. I think most of the security programs for webcams out there can do this. I've had good experiences with one program that also let you run an image server so you can view current images through the internet. The TRICKY part is how I would like to set up the network of wireless IP webcams. What I was hoping to do is have one machine that was dedicated to running the cameras. My goal was to use my two wireless routers so that I could have two seperate networks, one for the cameras, and one for all the other devices (laptops, desktops, game systems, printers). My question is, do I connect the router for the cameras to the computer that will run the security software, or do I plug that router into the router for the other devices? I've never worked with two of these small LinkSYS routers at the same time, so I'm not sure if I should be trying to create some sort of network bridge, or if I would maybe connect the camera router and camera computer via the WAN port of the router, since all of the camera images would be displayed on a image/web server running on that computer, accessed from the internet via the other router. Also, I've never worked with wireless IP webcams, so if there is any sort of quirck that I should know about that your average instructables user couldn't figure out, any help or advice with that would be much appreciated as well. Thanx Tony P.S. Eventually, I'd like to add in a strobe that would blink and a siren that would sound for a short time. I think I could figure this part out with "Pico Servers" and some relays.

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&lang=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!
