I tried that and it did not make a difference. Tried it in different combinations.
(1) just calling rcnetwork restart
(2) shuthing down knetworkmanager, rcnetwork restart, starting knetworkmanager again
(3) unplugging ethernet, then doing (2)
Nothing worked.
Here is what /var/log/messages shows after a rcnetwork restart
