internet connection fails

Version 20150529, updated yesterday, plasma5 desktop i586. Today no internet connection on this computer (the computers with opensuse 13.2 work fine). First attempt was a computer restart then rcwicked restart - same problem.I tried:

linux-top:~ # rcwicked status

So wicked tells me general failure but the card has an IP address, I can ping the router and other computers, only the gateway is not there. The network card seems to be OK then only the network settings don’t accept the gateway either through command line, Connection Editor or Yast Network settings. Everything worked fine yesterday. Could it have been one of the upgrades?

I don’t know if this has anything to do with the problem. Previously, I copied files from the NAS to /home/uli so the network card obviously worked - only it didn’t connect to the internet because there was no default gateway configured. In Yast -> Hardware I found under the network card driver the “modprobe r8169”. I was not sure if the module was loaded and just entered (as root) modprobe r8169. lsmod showed that the module was loaded. Now after the command rcwicked restart the network connected to the internet.
