Prioritizing between wwan and wlan

[Marius Kotsbak <marius kotsbak com>]

Hi!

Out of a IRC discussion, I got the impression that NM should prioritize wifi connections over mobile connections, but I don't see it:

Only wlan connected:

marius@marius-T1005:~$ route -n

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

0.0.0.0         129.241.166.1   0.0.0.0         UG    0      0        0 wlan0

129.241.166.0   0.0.0.0         255.255.255.0   U     9      0        0 wlan0

169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 wlan0

Both wlan and 3G connected:

marius@marius-T1005:~$ route -n

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

0.0.0.0         89.9.198.230    0.0.0.0         UG    0      0        0 wwan0

89.9.198.0      0.0.0.0         255.255.255.0   U     7      0        0 wwan0

129.241.166.0   0.0.0.0         255.255.255.0   U     9      0        0 wlan0

169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 wlan0

It seems like the last connected connection clears out the gateway of the old connections, and in the last case here, wwan gets the gateway and lower metric compared to the wwan that should be prioritized less than wifi...
