I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces
# The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy
When I restart
/etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway.
But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network.
I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?
