What is a historical connection?

What could be interfering with my Wi-Fi connection? Details inside...?

• First of all, I am on a wireless network with two other people and they're not experiencing any problems. Background info: I recently got a "new" computer (aka different one than I was using before, lol) and immediately noticed I was constantly losing a connection and I had to right-click the Wireless Network Connection icon in the task bar and Repair to get back online. I had to do that every ten or so minutes just to browse the web. And of course, I had a Very Low connection and just one bar. Before, with my older computer, I did have a LOW connection, but I didn't lose my connection and I didn't have to Repair it constantly. So I updated my OS drivers, made sure I had all the recent drivers to everything, I restarted the router, blah blah. I got 4 bars and everything was okay after that for a day or two. I was still losing a connection, but not as frequently. Then, the next day, the connection was low again... and so was the next day... etc. So I decided, "Ok, it's time to move the adapter (and the computer) until I get the best Signal I can get." I found a good place in the same room and it's been consistently 4 bars for over 24 hours... BUT!!! The problem: I am still losing my connection. And what's weird is, when I do lose my connection, it still acts like it's 4 bars and it SEEMS connected. But it's not. I have to Repair the connection, and then the internet works again. I plan to trade adapters (he has the same type I have) with my friend soon to see if there is a problem with my adapter. I have to wait a day or two to do that, so until then, I need some other ideas from you lovely people as to what the problem could be. This is a "new" computer, just had it worked on at the shop. I've had Trendmicro Anti-virus and Spysweeper all this time. They are updated and they are scheduled to scan often. I also use Firefox and the NoScript plugin. I am very very careful online. Just being unnecessarily detailed in case anyone suggests something I know isn't the case. Also, remember, aside from the low connection, my older computer never had these type of problems, where I have to repair to get back online. I am using a Cable Modem, SMC ez connect wireless g, on a DELL Dimension E510. We are using WEP. I've also tested it with and without my windows firewall and there is no difference. I really don't know what else to do.

• Answer:

  This may be a device driver problem. See if there is a newer driver for the wireless network interface on your pc and if so load it.
