I have attempted to do that, the wifi drivers from Dell are up to date.
I have concluded for sure that any type of long-term download disconnects the internet. Have tried to download World of Warcraft from the installer, and the internet disconnects. I then tried to download Battlefield: Bad Company 2 off Steam to test the internet, and see if it disconnected (it did). I can download at 1.6 or 1.7 MB/s for a few minutes, then the speed gradually reduces to 0, and the internet disconnects.
This is weird, because I was able to download Team Fortress 2 earlier yesterday, when I just got the Laptop. I was able to download that successfully for a long period of time...and then I installed the Windows 7 updates, which is when the problems started to occur.
Update on the situation: I have disabled the Dell Wireless utility, which has been responsible for some of the troubles. The internet is more consistent now, but I still get kicked off (although more rarely) for downloading simple things like QuickTime installers. I really don't know what's wrong with this laptop.
