Hello,
I've set up linux-wlan-ng for my prism2_usb and it works just fine for LAN-connections, pings, resolves etc. But it won't pass the gateway. DNS-resolving works, but see yourself:

tealc root # ping www.heise.de
connect: Network is unreachable |
If I enter the IP of heise.de, it says the same. If I enter a public DNS-server into resolv.conf, it can't resolv anymore.
This laptop has two LAN-devices: eth0 and wlan0. eth0 has 192.168.0.4 and wlan0 192.168.0.6. Both are enabled for forwarding on the router and work on other machines (as their IPs). I thought they might conflict with each other, so I brought eth0 down (ifconfig eth0 down) and even rmmodded the module. It won't work then too.
I've no idea what to do and would really appreciate any suggestions. 
Thanks,

[edit] solution:
eth0 has to be in e.g. 192.168.1.4 and THEN you have to add a new default-route for wlan0, then it works. A pity that I have to change that each time I want to use wlan0 |
