Comment # 1 on bug 908472 from Karl Cheng

Under current openSUSE versions you definitely can 'forget' a wireless network
under KDE Plasma 5.

I'm not sure whether this was an issue in 13.2, but given this isn't really
relevant now I'll close this issue.

If you have any other problems with current openSUSE versions, please file a
new bug. Thank you!
