I have a Latitude D810 running Windows XP. My wifi connection will cut out and reconnect anywhere from a few times a minute to about five minutes. Most of the time it connects back in a few seconds, but sometimes requires me to reboot to get it to show back up. My provider is ATT UVerse and the Dell uses Intel 2200bg and its client.
The problem began about a week ago when everyone in my house lost internet and television. We had the router reset and everything went back to normal for the television, but not the inernet. It became sluggish and inconsistent. That's also when my computer started having this disconnect issue.
I called ATT and the guy told me it looked like my connection had a bridge and he would send someone to fix it. The on-site guy told me that my internet was too fast because I'm 2000ft from their box. He said he was going to slow down our connection and that would fix everything
. Sounded pretty fishy, but I went with it.
Believe it or not, this fixed nothing. At this point I'm beginning to think my computer must be the problem. The internet is slow for everyone, but I'm the only one disconnecting like mad.
I've updated my Intel drivers, run a Microsoft Security Essentials full scan (found a couple "exploits" that it deleted, but had no affect on my problem), then ran it again in Safe Mode. No help.
Can a wireless card die? Is the ATT problem we had just a timing coincidence? Maybe there's a virus my scanner didn't find? Any help would be appreciated.
