    Wireless deauthenticated "Reason 6" - Realtek RTL8188CE

    Hi.

    I have a Lenovo x220 with a Realtek RTL8188CE wireless card.
    Things were working fine, but now I'm having problems with the wireless, seems to drop the connection, several times per minute.

    this is what i get from dmesg, it repeats (forever):

    Code:

    I'm using 11.04
    wired connection works fine.
    windows connections works fine.

    i tried the driver my realtek, but it still happens.

    any ideas?
    how do i revert to the default driver?

    is it possible to tell what is failing from the data i attached?
    what else should i provide?

    thanks!
    regards,
    Rodrigo.

    Re: Wireless deauthenticated "Reason 6" - Realtek RTL8188CE

    Same problem on my Gigabyte T1132N with

    06:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

    I also get these messages from dmesg and I also tried the drivers from realtek.
    Doing a bios update or changing stuff there didn't make a difference.

    My System: Kubuntu 11.10 (64bit) with 3.0.0-17 kernel
