Could you grab /var/log/messages file and attach it? What type of connection do you use (wired, WiFi, 3G)?

It appears that the kernel driver (forcedeth) is bouncing your link: either your router is having problems, the kernel driver is having problems, or your cable is faulty.  NM will disconnect the link when the kernel tells NM that the cable is disconnected, which is what has happened:

yeah i discovered that just thismorning. i think i got another Cable, so i'll try that.

Comment 7 Greg` 2011-07-30 00:02:46 UTC

i think i fixed it, turns out it was Dodgy Cables, Cables i got with the Modem not long enough. this Bug could probably be closed
