Unable to access Internet , Wireless + router

I have a Open Suse 10 system on a AMD athalong processor.
Configured wireless card to access home router D-Link.
IP address is assigned,
Able to access router’s http server.
Unable to access the internet from my linux system.
Tried the following
– disabled the firewall on my linux system. No change.
– Router is working fine. Posting this question over the same network ( different PC )

Please let me know what have I to do to fix the issue.

Got it working. I had to set the default gateway from the “Yast” -> routing panel instead of the value from the “Network card” routing tab

thanks and regards
