    Question lwl4965 not seeing 802.11a ntwork

    I have seen many discussion on network issues on not connecting. But I have not seen anything that can help on why my intel 4965 under Unbutu 11.04 not seeing any 802.11a 5ghz wifi.
    I changed my hardrive from Ubuntu 11.04 native OS to a Windows XP native and with Windows it is able to see my four 802.11a network SSIDs. But when I exchanged my disk with Ubuntu 11.04 I do not see any of my four 802.11a 5ghz SSIDs.

    I am able to connect to my other 802.11 B/G/N 2.4 ghz network with no problems. I am stump. My laptop is a Lenovo T61 Type 7658

    Thank you for reading this,

    The iwl4965 5ghz bug was fixed with this patch. And according to that patch you need kernel version 2.6.39 or greater.

    The way I see it you have 3 choices:

    1. Upgrade the kernel.
    2. Wait about a week and install Oneiric 11.10.
    3. Install the latest compat-wireless.

    I know that install compat-wireless fixes it because it fixed my iwl4965 5ghz.

    Thank you
