Switching wifi to cable?

Dear Linux friends,
To improve skype connections i would like to switch from wifi to cable in certain occasions.
Have setup wicked for this with yast. Network manager did not show an option for cable connection.

After reboot internet connection is still on wlan with cable plugged in, how can i switch?

$ip addr:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
