    Re: Wireless network problems with Ubuntu 12.04 LTS

    I ran the code, and install that driver. It's still not working.
    BTW, the rt73usb driver is for an external wifi doungle the I used when the internal wifi didn't work.

    What do you advise to do now?

    Errors during the installation?

    Check
    Code:
    iwconfig
    lsmod
    sudo iwlist scan
    dmesg | egrep 'rt2|rt5'

    When I asked you what to run I had a problem, (after the dhkm build) and then I deleted everything and install everything again and I didn't have any problems.
    The output:

    Code:

    Re: Wireless network problems with Ubuntu 12.04 LTS

    Try pure WPA2-AES (CCMP) encryption in your router. Check after that
    Code:
    sudo iwlist scan
    iwconfig
    ifconfig -a
    route -n
    cat /etc/resolv.conf
