I still cannot access the Internet under the final release of opensuse 11.3.
I had the same problem with RC2 in which I get “unable to reach network” when runing ping/wget both as root or as a normal user. I checked /etc/resolv.conf, disabled ipv6 and added a default gateway but nothing worked.
Here is a link to my post of the Pre-release/beta forum: Cannot Access Internet under 11.3 RC2

Please post the output of the following:
cat /etc/resolv.conf
/sbin/ifconfig
/sbin/route -n
/usr/sbin/iwconfig
You can strip the comments from the resolv.conf output, and only do the iwconfig
is you are using wireless.
Can you ping 8.8.8.8 (Google’s public DNS server)?

opensuse 11.3 is missing an entry in the routing table which might be the cause of the problem. Any idea on how to fix this? Why is the entry missing? I never had such a problem with any of the previous releases of opensuse.
Have you tried:
route add default gw 192.168.1.254
?
Great catch!
Is that 192.168.1.254 or 192.168.1.1 for his gateway?
I have the same connectivity issue (but with a default gateway in my routes) . Shall I post my info here, or start a new thread? Thanks.
Hi Gno, it sounds like you have a separate issue (if you do indeed have a default GW). Start a new thread please with your details.
Thanks, your solution fixed the problem 
How to make the fix permanent? Now I have to run the command after each reboot.
Sorry for double posting but I could not find the option to edit my post.
If you’re using the “traditional method” with ifup, then in YaST | Network Settings | Routing, you can manually specify the default gateway. You should set this to 192.168.1.254.
