i'm not using a modem..... i'm connecting to a wi-fi signal with a wireless card. The laptop i'm using is doing the same with no problems and my other computer in my daughter's room too. we have three computers with the same setup and only my main desktop is having problems. It started with the windows update that messed up zone alarms back on july 9th. I read up on the update and decided to get rid of zone alarms all together. But now I still can't access the web.
