One more thing I realized now: While the connection is cut off
the kernel/network-manager belives I am connected:
# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:16:ea:2c:6c:4a  
          inet addr:192.168.1.22  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:20368 errors:0 dropped:0 overruns:0 frame:0
          TX packets:21606 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:11031455 (10.5 MiB)  TX bytes:2927239 (2.7 MiB)
#

If I do during this time a ping of a remote host, interestingly:
- TX packgets and TX bytes go UP
- RX bytes go also up!
- RX packages stay the same, seems that the RX packets are not recognized

It seems with the changes now the TX is working, but RX is not.

Best wishes
