[PROBLEM] TP-Link TL-WN725N unable to get wifi working

[Maylo]

I looked through all the other topics regarding that specific wifi dongle but nothing worked. I'm on RC3 3.15.8+ kernel.

What i tried:

- Scanning for Network (no SSID's found)
-manually adding SSID and password through xbian-config (Cannot connect to network.)

Additional:
-wifi dongle is ok. it works on my laptop and also it worked in openelec
