[Problem] No Wifi with RC3 on B+

[josch]

Okay, so your wifi stick (TP-Link TL-WN725N) is recognized and it seems that the correct driver is loaded too.
Hmmm... or maybe it isn't the correct one!? You should have 8188eu, but you do have r8188eu loaded....
But I'm not really sure if the "r" one isn't equivalent...

Nevertheless it's certain that there is a problem with this driver version and your stick / firmware:

Code:

r8188eu 1-1.5:1.0: Direct firmware load failed with error -2

Do I understand right, that your wifi stick isn't listed anymore in xbian-config's network settings at all?
Maybe you could also post:

Terminal

sudo iwconfig

As I said, I'm not an expert - just trying to post what I would do in your situation.
And I'm thinking I would try also to compile the 8188eu driver by myself.
There's is a thread about your wifi stick and compiling the driver on the official RPi forum: http://www.raspberrypi.org/forums/viewtopic.php?t=62371&p=618445

PS: You can put your long outputs into [ code ] blocks instead of [ term ] ones.
