    Mint Wireless problem on Sony Vaio VGN-NR498E


    I've just installed Mint 13 on a Sony Vaio VGN-NR498E laptop and everything seems to work fine except for the wireless. It continually tries to connect and drops, tries to connect and drops, etc. The wireless controller is a "Intel Wireless WiFi Link 4965AGN".

    Thanks for any help that can be provided. Below is the output from the recommended utilities:

    Some people have reported the driver doesn't handle wireless n very well so they turn it off.

    Create an /etc/modprobe.d/disable_11n.conf file and add the following line to it and then reboot:

    options iwl4965 11n_disable=1
