IE problem or Linksys problem?

[Guest_imported]

I have a cable connection to the net. Ever since I started connecting my Linksys using DHCP and connecting my computers to my Linksys using DHCP (both at the same time) I started getting a problem with IE sometimes. A "Enter Network Password" window pops up. It will give the site name, Realm (which is Linkys...), name, and password. Im not forsure what network password it is asking for because none seem to work. Sometimes this happens and sometimes it doesn't. I have also noticed it when I first start up Kazaa, it will go ahead and log on, but the start page of Kazaa has a "401 error". I have no problem when Im using Netscape. Anyone have any ideas or know what the problem is. Thanks for the help
