[Bug 1477918] [NEW] Network Manager gives Wifi and Ethernet same metric
Public bug reported:
When the laptop is connected to the house's network using Wifi and Ethernet at the same time I don't get network connection .
But each one works alone meaning if i manually disable one of them i get network access .
As i found out the Network Manager gives eth0 and wlan0 same metric .
These are outputs that helps , all under default ubuntu 15.04 configurations .
Output of route -n when both (eth0 and wlan0) are enabled :
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.100.102.1 0.0.0.0 UG 1024 0 0 eth0
10.100.102.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
10.100.102.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0
Output of route -n when only ethernet is enabled :
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.100.102.1 0.0.0.0 UG 1024 0 0 eth0
10.100.102.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
One more thing if i disconnect from wifi then reconnect again (i get network access), i get this route -n output :
