I have my wireless card up and running, and I can get to the router's web interface with the other wired nic unplugged and I can ping it, and the router assigns it an IP, but i cannot get out to the internet

the errors are mostly DNS errors, cannot find host, and the DHCP gives it an IP but no nameserver info, I added those manually by IP, but still have the problem, here is my ifconfig, the wireless card is eth1, wep is disabled for now until i can get this up and working and then i'll try to set that up again

Are you running eth0 and eth1 at the same time? That may be causing some problems. You can take down eth0 with ifconfig eth0 down and see if that improves the situation or next time boot without connecting the cat5 cable.

I'm assuming that means that you added your ISPs DNS servers to your /etc/resolv.conf file, but if that isn't true, then you need to do that.

I used the Yast wizard, but here is the content of that file:

i will try rebooting with it unplugged again, i tried taking it down and that didn't solve the issue, and as i said the router's web interface came up, so it can use the card to connect

rebooting with the other card unplugged did not work

another oddity, i can access servers by IP on my LAN, but not external IPs or external domain names with the wireless card only, it's like it loses the gateway but can hit the access point

That line looks odd to me. You might try commenting it out (add a # and then save the file) and see if that helps.

i went to take that out, and this was the file contents:

What is the output of route -n? Specifically, is the gateway set to your router IP address?

Probably won't do anything, but just try your firewall. Check that it isn't preventing the internet from getting in. Also i had forgotten this when I was setting up my network last month, proxy! Check to see if those settings are right.
You said that you know that your wireless is up and working, are you using anything to see the signal strength? I would recommend kwirelessmonitor.
Well those are my thoughts, i hope that they help you.

i've installed kwirelessmonitor and it shows good signal stregth but 0% link

that routing table shows eth0 as the interface to use for the gateway, is there a way to change that?

I got it working! Thanks for the help, the missing link was

linux:/opt/kde3/bin # route -n

0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1

Seems slower than in Windows though, although signal strength and link are high and noise is low and it's 11mbps

I am finding I have to type
route add default gw 192.168.1.1 dev eth1
at the command line as root every time I reboot. I have tried configuring the /etc/sysconfig/network/routes file from many examples online, and configuring the routing in YaST following the output of route -n exactly, but nothing has worked but "route add default gw 192.168.1.1 dev eth1"

any ideas?

I've had that problem my self. Every time I restart my wireless config dissapears. I solved it by writing a script with the commands I needed to get it up and running.
I.e:

#!/bin/bash
route add default gw 192.168.1.1 dev eth1

You can save this to your /usr/bin and run it manually. I used this solution because I move my laptop between to locations which requires different setups.
If you want this to be run automatically when you start up, it should work if you save your script to /etc/init.d/

I think it automatically reconfigures the network settings/gateway every time I boot and it sees eth0 is disconnected or tries to use eth0 to hit the gateway

The init.d directory contains commands that are run everytime you boot, so if you put a script in there should load your configuration on boot. Yoou may want to remove any other script trying to configure your network.
