i have a linksys wireless router connected to my computer. my roommate is using a wireless card to get on the internet. for 2 weeks, her computer was fine. but the past 3 weeks, she said she can't get on to the internet. she tries going on yahoo and it kicks her off. she deleted her cookies and that didn't help. she is recognized on our network, has excellent signal strength, yet her connection is very slow.
any suggestions?
