Few thoughts: wpa-supplicant is needed.

eth0, lo, wlan0: seems fine to me. 

I suggest you disable/remove avahi:
$ sudo invoke-rc.d avahi-daemon stop;
$ sudo ifdown wlan0:avahi;

What's wmaster0? 
Also note, Avahi's a piece of **ap software TBH and mucks up lot of stuffs.

Do that and then reconfigure your interface with Knetworkmanager or whatever its called.
