Why does this crap always happen to our computers? This time it's Linda's laptop. Every time she reboots, it work fine for 10-15 minutes, and then the connection drops. But wait - it's only the browsers. She can still use IM, she can still ping the router and yahoo.com from a command prompt, but neither Firefox or Internet Explorer can bring up any web pages. Not even the router.
I've run virus and malware scans, I've checked the HOSTS file, restarted a couple services, and changed many router settings, but nothing has fixed the issue. I've currently got Spybot running a full scan in safe mode on her machine, but I'm not hopeful.
Here's the interesting thing: I've found a number of other sites with people describing the exact same problem, and no one has found a solution other than reinstalling the operating system. Aack. Guess if all else fails, I'll try that this weekend.
