SuSE

Hi I am new to Linux. I installed 11.4, it went smooth and everything was working fine. After Update i rebooted the system and all of sudden internet connection is not working.
Could any one tell me how to check and change the settings.

/sbin/ifconfig -a will show you the interfaces and what is defined for them.

In general, the "easiest" way to setup the network in openSUSE (SUSE) is using YaST (yast).

You can try doing:

rcnetwork restart

as root to see if that gets the network going again. Also, if possible, you could try switching away from using NetworkManager to using the traditional ifup/down script method... that's in the General section of the network setup in yast... however, if this is wireless, doing that might cause you more confusion.... ymmv.
