can you ping 126.96.36.199 ?
Also, what's the output of the following:
(that will show you the default gateway, can you ping it?)
If you can ping the default gateway but not access the "internet", check your nameservers. You can configure that from Yast - just type yast2 in a terminal and go to the networking menu. 188.8.131.52 is the google nameserver, start with that.
