    Question Realtek RTL8188cus usb wifi poor/no connection

    Hi forum,

    I am having difficulty getting my tp-link WN-723N (Realtek RTL8188cus) to work.
    I have compiled 8192cu from realtek and blacklisted the native modules. This is a clean install of ubuntu 12.10.

    From ifconfig it seems I am dropping a lot of packets.

    Here is the ouput of some wireless related commands:

    Code:
    lsusb | grep Realtek

    Let's disable it and see if things improve:

    modprobe -r 8192u
    modprobe 8192u
    exit
    Any improvement?

    Re: Realtek RTL8188cus usb wifi poor/no connection

    Thanks. Done.
    There may be a slight improvement with that. I can now connect to services (for the most part) but my connection rate drops to zero every few seconds and sometimes just remains flat.

    Any other options?

    In order to know or at least guess what to adjust, we need to see what's going on as it's misbehaving. When it does so, please run:
    Code:
    dmesg | tail -n50 > j97.txt
    Find the file j97.txt in your user directory and post it here and give us the link in your reply: http://paste.ubuntu.com/

    Re: Realtek RTL8188cus usb wifi poor/no connection

    I suggest you try the backported driver from kernel version 3.11. First, remove the blacklist for rtl8192cu. Second, uninstall 8192cu:
    Code:
    cd Desktop/RTL8188C_8192C_8192D_USB <---or wherever you compiled the driver
    sudo make uninstall
    Then, I suggest you download this to your desktop: http://www.kernel.org/pub/linux/kern...-rc3-1.tar.bz2 Right-click it and select 'Extract Here.' Now open a terminal and do:
    Code:
    cd Desktop/backports-3.11-rc3-1/
    make defconfig-rtlwifi
    make
    sudo make install
    sudo modprobe rtl8192cu
    Now your wireless should be working properly.

    You will have compiled the driver for your currently running kernel only. When Update Manager installs a later linux-image, after reboot, re-compile:

    Code:
    cd Desktop/backports-3.11-rc3-1/
    make clean
    make defconfig-rtlwifi
    make
    sudo make install
    sudo modprobe -r rtl8192cu && sudo modprobe rtl8192cu

    Thanks Chili, but runnning:

    Code:
    cd apps/RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105/
    sudo make uninstall
    Returns the error:

    Code:
    make: *** No rule to make target `uninstall'. Stop.
    What's happening here?

    Is that the directory where you ran the install; make and sudo make install, originally? I don't know for sure, it's not my system. You want to be in the same directory as the Makefile.

    That is the directory I ran the install script. However I ran no make commands and there is no Makefile in that directory.

    Inside: '/RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105/driver/'
    there is a locked directory named 'rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105/' and a tarball of the same name.
    I can see that the tarball does contain a Makefile.

    Have I done something stupid or maybe missed an important step?

    I took the same steps as can be seen on the first post here http://ubuntuforums.org/showthread.php?t=2092934 but also used chmod 755 and added 8192cu to /modules.

    Any clearer what the problem is?

    No, nothing stupid. That package is designed that way. The desired Makefile is within that directory you see in the "driver" folder. (if not, delete the folder, right-click the .tar.bz > "Extract here")

    You'd have to cd to that directory within the 'driver' folder, and run "make uninstall" from there. It should get the job done (from within '/RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105/driver/') -
    Code:
    cd rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105
    sudo make uninstall
    Closely watch the output and report back if any errors occur.

    I took the same steps as can be seen on the first post here http://ubuntuforums.org/showthread.php?t=2092934 but also used chmod 755 and added 8192cu to /modules.
    /modules or /etc/modules file? Whatever it is, you'll have to undo that as well. After cleaning everything up, proceed with the installation of the backported driver.
