you can use net-analyzer/ifmetric.
I found this solution not satisfying, but don't remember why.
I guess some corner cases.
I have bonded the interfaces on my laptop. The bonding driver will prefer
using the wired when
it is connected.
Here is my /etc/conf.d/net:
# eth0
config_eth0=( "null" )
# wlan
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
config_wlan0=( "null" )
modules_wlan0=( "!plug" )
ifplugd_wlan0="--api-mode=wlan"
# bond
slaves_bond0="eth0 wlan0"
dhcpcd_bond0="--noipv4ll --nolink -t 15"
config_bond0=( "dhcp" )

Kfir

Hi all,<br>
<br>
For my home network I am generally using wireless to get connected to the<b=
r>
network and the internet.<br>
<br>
However for copying some large files I use the wire.<br>
<br>
That means I get 2 IPs in the same range.<br>
And both interfaces get the same metric : 0.<br>
<br>
I found out I can modify the metric for the default route using metric_wlan=
0.<br>
Code:<br>

<br>
(this is not the full routing table)<br>
However this changes the metric of the default route.<br>
Not of the route that is specifically for the local network.<br>
of course I can do this manually.<br>
However that is alot of hassle and seems to be something that should be<br>
configurable use files.<br>
<br>
Does anyone knows how I can accomplish this? Or how I can change the metric=
for<br>
each route for the wlan0 interface?<br>
<br>
Thanks in advance!<br>
