Computer becomes very laggy when using modified 802.11a driver RRS feed

  • Question

  • Hi all,

    I have performance problem with 802.11a on a Quad Core. (802.11b works fine)

    The 802.11a driver shipped with SORA SDK crashes at the beginning. Then I saw the posting on this forum.

    I changed core affinity of send and recv to core 2, and changed veterbi thread to core 4, for the driver to work.

    And now after enabling 802.11a driver, CPU goes very high (100% on core 3 and 4, 80-90% on core 1 2)

    and mouse move become very laggy.


    Any ideas why this is?

  • 802.11a needs more CPU resource.

    It is better to  upgrade your system.
