    Re: Can't Connect to Wireless Networks

    Which encryption do you use? Try pure WPA2-AES (CCMP). Check you router manual

    Re: Can't Connect to Wireless Networks

    Your other devices do not use an Ahteros chip. They are known to be "special"

    Re: Can't Connect to Wireless Networks

    As I mentioned here http://ubuntuforums.org/showthread.p...5#post12737085 I am aware you are NOT using an Atheros chip. Confusion in #15

    On which channel does you router send? Check

    Code:
    iwlist chan
    how many channels are available. Set the channel to fixed mode if only 1-11 are shown.

    Edit: Encryption to pure WPA2-AES, not mixed WPA/WPA2
