Just a suggestion:
Do like you did in the router setup - 192.168.0.1 in browser window, enter username and password, go to dhcp, make current ip static from dhcp, done there.
go to yast, setup network card, edit config, set the static ip there. You will have to set the mask, always 255.255.255.0 unless you changed it. You should add default gateway 192.168.0.1, and maybe even add your isp's dns lookup servers - found in status of the router setup.
Don't have a clue if it will work but the one thing I noticed from your post is you didn't set up the card in yast to static ip.
