I got a Sony Vaio Laptop with an e100 wired lan and ipw2200 wireless lan. Both interfaces work fine, but only when activated on their own.
When I first bring up the wlan, and after that bring up the normal cable lan interface, only the wlan can ping machines on the local net and internet. If i do it the other way round, i can ping via the cable lan, but not using the wlan interface.
Can I make both interfaces work as normal at once? I guess it has something to do with my route settings maybe...
Although the system is debian, I made a custom network start script which goes like this:
(eth0=wireless, eth1=cable lan)
iwconfig stuff , essid, wep and so on... this should be alright.
ifconfig eth0 192.168.1.96 netmask 255.255.255.0
ifconfig eth0 up
ifconfig eth1 192.168.1.92 netmask 255.255.255.0
ifconfig eth1 up
route add default gw 192.168.1.1
However, only the first device brought up "works"....
