pinging google's dns (after rebooting): "64 bytes from 8.8.8.8: icmp_seq=50 ttl=58 time=54.4 ms 64 bytes from 8.8.8.8: icmp_seq=51 ttl=58 time=76.8 ms 64 bytes from 8.8.8.8: icmp_seq=52 ttl=58 time=99.0 ms 64 bytes from 8.8.8.8: icmp_seq=53 ttl=58 time=637 ms"
but then suddenly "eth0:avahi Link encap:Ethernet HWaddr ec:f4:bb:60:df:ea inet addr:169.254.12.153 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 Interrupt:20 Memory:f7c00000-f7c20000" appears and: "From 169.254.12.153 icmp_seq=54 Destination Host Unreachable" strange thing is, that I can still reach all clients in the same subnet (192.168.2.x).
