I installed openSuse 11.0 on my laptop (Dell Inspiron 6400, intel core duo 1.8Ghz, 1Gb Ram).
My internet connection is DHCP-type. The connection (via KnetworkManager) works very well when I turn on my computer.
After a simple reboot, the internet connection is not there anymore (KnetworkManager doesn’t detect any connection).
Nice to see your answers… Nevertheless, I’d like to use Knetworkmanager as network interface because I sometimes use a wireless connection. So, these are the outputs of the commands asked by Magic31 :

With what you’ve posted networking seems to be working fine.
The output tells us you have a connection on your wired network card, ip 139.165.199.142, dns/nameservers 139.165.32.13, 139.165.40.1 & 139.165.12.5, and your gateway is set to 139.165.199.129.
Are those the correct settings for your network?
If it’s only the wireless bit you are having issues with, as a first you could try to delete the wireless configuration by going to YaST > Network Settings, select the wireless nic and then delete.
Save this with the Finish button and then reconfigure the wireless settings again using Network Settings.
This can often set things straight again.
I’m not to familiar with KDE’s knetworkmanager as I’m mainly a GNOME user. Are you using KDE 4.0 or 3.5? There could be a difference there… others here might be able to confirm that.
