8192cu driver for tplink 8200nd problem

erick_morales_1006 · February 3, 2013, 6:59am

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:


/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

binutils - 2.22-17.2.3
binutils-devel - 2.22-17.2.3
binutils-gold - 2.22-17.2.3
cross-x86_64_binutils - 2.22-17.2.3
kernel-desktop - 3.4.11-2.16.1
kernel-desktop-devel - 3.4.11-2.16.1
kernel-firmware - 20120719

Any help is highly appreciated.
Best regars
Erick

Let us see:

/sbin/lspci -nnk | grep -iA2 net

Also, install rfkill and let us see:

/usr/sbin/rfkill list

But your wireless is Intel Centrino?

erick_morales_1006 · February 3, 2013, 8:22am

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

erick_morales_1006 · February 3, 2013, 8:46am

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

sudo /sbin/modprobe -rv iwlwifi

To re-insert

sudo /sbin/modprobe -v iwlwifi

You might also want to try probing the other device off and then on

sudo /sbin/modprobe -rv rtl8192cu

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:


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


su
modprobe -v rtl8192cu

plug in the wireless device


echo 2357 0100 > /sys/bus/usb/drivers/rtl8192cu/new_id
exit

However the wireless is still not recognized with iwconfig.

Did you check dmesg to see if the firmware is missing?

Of course, it is possible that rtl8192cu is NOT the correct driver for this
device.
