Did you look in the Device Manager to make sure your NIC card is working?
Try an IP renew or refresh.
Just a suggestion.
Device manager says this device is working properly.
I tried to repair the connection-but still no internet.
I opened the command prompt and typed ipconfig /release and then shut down my computer and my router and my cable modem.
Turned on the cable modem.
Turned on the router.
Turned my computer back on.
Now i have internet!
But now i have a new problem--i cannot install zone alarm or avast??? What the HECK??
edit: Avast simply says there was an error and the setup cannot be completed???
edit #2: There was an error during the setup process is the exact message it gives--i tried downloading a new avast home setup.exe but it gives the same error. I got the download from the avast website.
