I have installed Suse Linux 9.2 Pro on my laptop, which has an Intel Pro 2100 wireless network adapter. I installed ipw-firmware as requested by Yast, and it has been configured as eth1. On booting the system it is assigned an ip address and subnet mask by my Belkin router. Eth0 is set to manual. All WEP and ESSID are set correctly.
If i ping the router, then i get an unreachable message. If i ping eth1 it's ok. I can connect to the internet through eth0 if i do ifup eth1, but i can never get a connection if i try to go wireless.
Please help as i'm tearing my hair out here!!!

Wat network ur router on? 192.168.x.x?
Are the on the same network group?

Is ur router having a firewall that does not allow ICMP packets? No pinging or anything like that?

To troublehoot this kinda problem,

1. Bring down ur wireless network adapter and bring up ur eth0. Ping it with other boxes.

2. Do the other way round to again for both eth1 and eth0 again.

3. Also Test on this conditions, use virtual ips for both the network card.
i.e.:
root@richard# ifconfig eth0:1 192.168.x.x.x

If both doesn't ping to that router, its the firewall.

Last piece of advice, divide and conquer, do the thing u are very very confident will work first.

Cheers man.

I don't think the problem is being caused by Linux firewall because it still fails even if i disable the firewall completely. I can ping the router from eth0. eth0 will ping itself and so will eth1. eth1 cannot ping the router though.

Are u cofirmed that ur wireless lan card is working properly?

Can u confirm ur eth1 obtained an ip from the router?

Do u have any firewall on ur own notebook?

If ur driver is installed as module, is it loaded? Type "lsmod" on the konsole to check.
