Solved: Internet keeps cutting off
Hello, I am using a Windows Vista SP1 Home Premium Edition, recently upgraded to SP2. My computer is a Dell Inspiron 1420 (laptop) with Intel Core 2 Duo T8300 (2.4GHz, 800Mhz, 3M L2 Cache). I have both IE7 and Google Chrome. I am currently using Google Chrome. A year ago, I had the Artemis Trojan virus and with the help from staff on here, I was able to get it removed. For the past year and a half, I had been playing the Sims 3 on my laptop but 3 months ago shortly after I got the Sims 3 Ambitions, my video card was no longer able to handle the game and my laptop has been overheating ever since I began playing the Sims 3 games. I usually smell something burning after I've used my laptop for an extended period of time. It overheats even if I use my laptop cooling fan.

Lately when I'm on the internet, my internet connection periodically cuts off and I usually go to the Connect To a Network page, disconnect from my network and then reconnect and most of the time, I get reconnected to the internet. The weird thing is, when my internet cuts off and I go to the Connect To a Network page, it says I'm still connected even though I'm obviously not. Lately since I've upgraded to SP2, it's been getting worse. When I upgraded to SP2, my sound device has stopped working and I had to reinstall that and now it's working fine. I was wondering if my internet is dropping out because perhaps my wireless card was damaged in the process (either burned out by the Sims 3 or affected by some changes made by the upgrade to SP2)? Or is it because a lot of people in my neighborhood now have wireless internet and I'm getting kicked off the network constantly because of it? Or is it some leftover damage from the Artemis Trojan virus I had last year? Or is there a really simple and easy explanation for this? (I'm hoping for that one ) Any help would be greatly appreciated. Thank you in advance for reading this.

It's difficult to not suspect heat damage, but let's look for other things.

Do you have the disconnections with ethernet also?

Are there any other computers on your network? If so, how are they connected and do some or all of them disconnect at the same time?

What is the brand and model of your modem or modem/router? If you have a separate router what is its brand and model?

For when you have a (wireless) connection and for when it has been lost please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Thanks so much for your help, TerryNet

When my internet cuts off, I don't think the ethernet cuts off as well because I can usually reconnect right away.

There are 3 other computers on my network, there are 2 other wireless laptops and 1 desktop computer. Sometimes there are more than one of the computers on the network at the same time. Usually there are 2 or 3 on at the same time.

The brand of my modem is Linksys wireless N router and the model is WRT120N.
