    Hi everyone.

    This past weekend I went out of town and took my Windows 7 laptop with me -- since I returned home, it has been unable to connect to my wireless network. Other devices in my home connect to the network just fine, and the problem laptop has always been fine until now. My network card is an Atheros AR9285, and I'm attempting to connect to a Medialink router with WPA password protection and AES encryption.

    My wireless network icon in the task bar has a yellow sign with an exclamation point in it. It says "No Internet access."

    I have tried:

    -rebooting the computer
    -unplugging and restarting the modem and router
    -going to the command prompt and renewing my IP address with the command IPCONFIG/RENEW

    None of this works.

    Like I said, all other devices in my house connect to the wireless network with no problem. It's just this one laptop. Any guidance would be greatly appreciated. Thanks!

    Three things to try ...

    If you have McAfee please see the sticky thread at the top of this (Networking) forum.

    Disable encryption on the router and try to connect. If successful you can probably re-enable encryption and reconnect.

    Revert to a System Restore Point before the weekend.
