Does anything appear in dmesg when the connection is flipping? Or /var/log/messages?
Created attachment 565416 [details] some /var/log/messages log Each time there is that connection flipping the /var/log/messages has several messages added.
I've seen this behaviour but AFAIK it disappeared. But it didn't happen to me always, so I'm not 100% sure. Please test NetworkManager-0.9.3.997-0.7.fc17 from updates-testing repository.
Yeah, it's been fixed in recent updates. http://koji.fedoraproject.org/koji/buildinfo?buildID=308207 Feel free to reopen if you encounter problems.
