    Default Help with realtek USB 802.11 N

    I've tried many things, just starting off in Linux.
    Running latest updates of SUSE KDE (GNOME needs updating but same issues).

    my lsusb is:

    I've gotten close using an ubuntu forum editing the blacklist.conf file pointing to the rt2800 ralink driver, the system saw my device, had LED activity and got as close as attempting to connect, but it would never resolve.

    Some assistance would be much appreciated for this newbie!

    Thanks!

    http://linuxwireless.org/en/users/drivers/rtl819x looks like the rtl8192cu driver should work with my device?!? Can't figure out the implementation though.

    Thanks again!

    No, that is NOT the correct driver. It is rtl8192cu, which is a regular part of
    the kernel.

    There is a major bug in that driver that was just found. It will be some time
    before the fix percolates through the system. If you cannot wait, you will need
    to patch the kernel sources and build your own kernel. If that is what you want
    to do, let me know.
