Hi,

I have installed and configured my wireless card with a static IP, and it works I can ping and connect as normal. However when I unplug my eth0 (wired) the wireless drops off the network.

When the wireless and eth0 are connected the route table looks like this:

Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
10.20.28.0      0.0.0.0         255.255.252.0   U         0 0          0 wlan0
10.20.28.0      0.0.0.0         255.255.252.0   U         0 0          0 eth0
0.0.0.0         10.20.28.10     0.0.0.0         UG        0 0          0 eth0
When eth0 is not connected it looks like this:

Code:
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
10.20.28.0      0.0.0.0         255.255.252.0   U         0 0          0 wlan0
Therefore I added a route:

Code:
ip route add 0.0.0.0/0 via 10.20.28.10 dev wlan0
And the routing table looks like:

Code:
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
10.20.28.0      0.0.0.0         255.255.252.0   U         0 0          0 wlan0
0.0.0.0         10.20.28.10     0.0.0.0         UG        0 0          0 wlan0
But the wlan0 is still not on the network.
