networkmanager thinks it activated the device but i can not even ping the
gateway! what could be the problem here?

and also the routes

================================================

It appears there is a VMWare interface running vmnet1. My suggestion is 
to take down the vmnet1 interface so that your routing table looks like 
and restarting NM

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 ath0
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 ath0

If your pings now work, you have a starting point for diagnosis.  I do 
not believe that NM can deal with the VMWare interface vmnet1.
