    Question Wifi problems once again

    Hello everybody,

    once again it is me with WiFi problems. Let's jump straight into it:

    I re-installed Ubuntu 13.10 on my laptop.

    Code:
    phil@phil-laptop:~$ uname -r
    3.11.0-15-generic
    Here is the output of lspci:

    Code:
    02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)
        Subsystem: Hewlett-Packard Company Device [103c:1629]
        Kernel driver in use: rtl8192ce
    The driver that comes with the kernel did not really work. The connection was unstable and slow. I therefore tried to install the Realtek driver just to find out that there have been some changes in the kernel headers which lead to the problem that the Realtek driver will not compile properly. I then tried this driver I found somewhere on the forums[1]. Good side: it compiled alright, as far as I can tell. Bad side: WiFi is still unstable and slow. So I would like to ask everyone of you if you happen to posess any knowledge that might help me, because this is getting really annoying.

    I also tried disabling the hardware encryption/enabling software encryption, but that did not seem to help, assuming I did it right. Any help on this would greatly be appreciated!

    Have a good night,

    Deactivate IPv6 ("Ignore") in the NWM settings.

    Re: Wifi problems once again

    Sorry for not replying earlier, but I had some work to do. I deavtivated IPv6 but the connection still drops from time to time, whereas there are no problems on any other devices.
