i have a problem with broadband?

i have a problem with broadband it automatically disconnects .
and prevents from opening any site and shows message 'page cannot be displayed' stops downloading , but in network connections it shows connected and it also doesn't disconnect with manual attempt . and computers are still there in qiuck launch but with no lights . Is this virus or something else if virus then please tell any good anti virus .
when it disconnects window apears like windows 98 (old look)
for few seconds then restores to normal xp look again . I have to restart my computer to reconnect and same thing happens after sometime
