tp-link tl-wn8200nd and rtlwifi_new drivers

[Alberto Mardegan]

Hi all!
   I unfortunately purchased a Tp-Link TL-WN8200ND USB wireless adapter, 
which is not working in Linux (there are several reports of this in this 
ML already, so I won't bother you with another one).

I wanted to test the new rtlwifi_new drivers from
   https://github.com/lwfinger/rtlwifi_new
to see if by any chance they could help having this device running. I 
built then and installed them (in Ubuntu 14.04), but I don't know how to 
make sure that the kernel is using the new drivers and not the old ones.
Is there some hint in the syslog which could tell me whether I'm now 
using the new or the old drivers (for the record, it still doesn't work)?

Ciao,
   Alberto

Please list the USB ID for your device as shown by lsusb.

If you did the 'sudo make install' step without error, then these drivers are 
loaded. All but one of the drivers in rtlwifi_new are for PCI devices, but you 
have a USB model. Thus only driver rtl8192cu might be used by your device.

Here's the first few lines of syslog when I insert the device:

I found this old conversation where you were helping another user having 
the same device:

http://www.spinics.net/lists/linux-wireless/msg109223.html

Did you get the device you ordered from e-bay? I wonder if they are all 
the same, or if there are hardware variants which are working out of the 
box.

Ciao,
