hi. my wireless card used to work great i had no problems until i got spyware message that said something like "winanonymous can delete all spyware malware from you infected computer...... etc" this messae would constanly pop up whenever i would connecct to the internet. it allways disconnected me and restarted my computer. no spyware virus scan detected anything and eventually i was unable to connect to the internet using wireless. i formatted and installed the same op but my wireless woud still not work. eveytime i try to connect i see "connecting to bswee" then "windows cannot connect diagnose connect to diff network." it isnt my netwrok because i tried to conect to nmy school's network and i get the same problem. strangely though one morning i got up and was able to connect to my network for about 2 hours then it got dc and couldnt connect again. i think its because my roomate connected to the network with his laptop. i think as long as someone else is on a network i cannot connect to it. im not sure. but its set to automatically obtain ip. i did eveythin possible... updated drivers, installed xp, nothin works. can someone help me please. is a intel(r) pro wireless 2200bg.
