Hi, i have the same issue, after boot there is only device:wlan0, but after some time I have eth0 and eth0:avahi $ sudo ifconfig bond0 Link encap:Ethernet HWaddr 96:06:73:94:b5:98 UP BROADCAST MASTER MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) eth0 Link encap:Ethernet HWaddr 02:c8:06:83:22:ef UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:50 eth0:avahi Link encap:Ethernet HWaddr 02:c8:06:83:22:ef inet addr:169.254.8.145 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 Interrupt:50 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:168 errors:0 dropped:0 overruns:0 frame:0 TX packets:168 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:14624 (14.2 KiB) TX bytes:14624 (14.2 KiB) wlan0 Link encap:Ethernet HWaddr 98:3b:16:e8:e7:b3 inet addr:192.168.0.12 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::9a3b:16ff:fee8:e7b3/64 Scope:Link inet6 addr: fd00:8494:8cb6:68e2:9a3b:16ff:fee8:e7b3/64 Scope:Global inet6 addr: 2a02:8109:a53f:ff3c::3/128 Scope:Global inet6 addr: 2a02:8109:a53f:ff3c:9a3b:16ff:fee8:e7b3/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:949 errors:0 dropped:0 overruns:0 frame:0 TX packets:553 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:118594 (115.8 KiB) TX bytes:154410 (150.7 KiB) which results in 2 default routes for IPv4 (IPv6 is fine) $ sudo route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default * 0.0.0.0 U 1002 0 0 eth0 default hitronhub.home 0.0.0.0 UG 1024 0 0 wlan0 link-local * 255.255.0.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.0.0 * 255.255.255.0 U 0 0 0 wlan0 The easy workaround is to delete default route on interface eth0, which is not connected. $ sudo ip route del default dev eth0
