Thread: 8192cu driver for tplink 8200nd problem

  1. #1

    Default 8192cu driver for tplink 8200nd problem

    Hi, I am trying to use the tplink 8200nd (Launch date:26/10/12) with opensuse 12.2 (x86_64) with no success. According to the fcc code (TE7WN8200ND) the chipset used is an rtl8192cu.
    I have installed the compat-wireless drivers 3.7 (from Index of /repositories/driver:/wireless/12.2-update) which has support for this chipset, however the wireless is still not recognized. I also tried to compile the wireless driver from realtek web page, but the compilation gives me the follow error:

    Code:
    /usr/src/linux-3.4.11-2.16/arch/x86/Makefile:96: CONFIG_X86_X32 enabled but no binutils support
    However I have installed the follow packages
    1. binutils - 2.22-17.2.3
    2. binutils-devel - 2.22-17.2.3
    3. binutils-gold - 2.22-17.2.3
    4. cross-x86_64_binutils - 2.22-17.2.3
    5. kernel-desktop - 3.4.11-2.16.1
    6. kernel-desktop-devel - 3.4.11-2.16.1
    7. kernel-firmware - 20120719


    Any help is highly appreciated.
    Best regars

    Let us see:
    Code:
    /sbin/lspci -nnk | grep -iA2 net
    Also, install rfkill and let us see:

    But your wireless is Intel Centrino?

    In fact, the internal wifi is an intel centrino, however in the previous list of devices does not appear the realtek device. Searching for the device with hwinfo i have found the next:

    So the Intel internal device is no use? Is it working? Is it active? Is the wireless switched ON?

    This is somewhat new to me. Except that I did test a USB device on a machine which already had a internal device, I had to blacklist the internal IIRC

    The internal device is active and working without any problem. However I have tested other usb wireless devices like the D-Link DWA-130 (with the driver rt2800usb) and they have worked like a charm without blacklist the internal wifi.

    Taking into account your comments, I have tried disconnecting the internal wifi without having any success to recognize the external 8192cu wireless.

    An easy way to remove your internal is

    Code:
    sudo /sbin/modprobe -rv iwlwifi
    To re-insert
    Code:
    sudo /sbin/modprobe -v iwlwifi
    You might also want to try probing the other device off and then on

    Code:
    sudo /sbin/modprobe -rv rtl8192cu

    Code:
    sudo /sbin/modprobe -v rtl8192cu
    Assuming rtl8192cu is the exact module name?

    That device (2357:0100) is *NOT* in the device tables for rtl8192cu, either in
    the kernel driver or the one from the vendor. No amount of loading or unloading
    of drivers will make any difference, except in the following sequence of commands:

    Code:
    su -
    modprobe -v rtl8192cu
    echo 2357 0100 > /sys/bus/usb/drivers/rtl8192cu/new_id
    exit
    If that works and you get wlan0 in the /usr/sbin/iwconfig list, then let me know
    and I will push the change. Note: These commands will be needed after every rebppt.

    First of all, thanks for your replies.
    1.- I have tried to load/unload the drivers in different ways without any results, as was written by lwfinger.

    2.- Also I tried the sequence of commands given by lwfinger but it was no change in the system, the tplink 8200ND (rtl8192cu) continue without be recognized. I have executed the sequence of commands given by lwfinger in the follow order (just as is described in http://www.ha19.no/usb/ in the topic "Adding new vendor and product IDs to an existing USB driver on Linux"):
    • unplug the wireless device
    • execute

    Code:
    su
    modprobe -v rtl8192cu
    • plug in the wireless device

    Code:
    echo 2357 0100 > /sys/bus/usb/drivers/rtl8192cu/new_id
    exit
    However the wireless is still not recognized with iwconfig.
