wireless wlan0 has ip but no internet access on suse 9.1
I have suse 9.1 professional on a laptop (dell inspiron 600m) with a proxim rangelan-ds pcmcia wireless card. I am able to get an IP address from my router (192.168.1.105) and can ping, http, ssh my other computers on the local network (say, 192.168.1.1 my router or 192.168.1.100 my other computer). But I cannot reach outside of the network. When I use just my regular eth0 adapter, everything works fine (even though dmesg says that it cannot find ipv6 router for wlan0 and eth0.)
I have tried editing /etc/resolv.conf and putting the IP addresses of my ISP's servers manually but that did not fix things.
Can anyone point me to a guide or something on how to set it up? Do I need to install the dhcp server? If so, why does it work for my eth0 without installing anything else?
