Comment 65 for bug 82335

I have the same problems you have, but I would like to add an observation:

- Using a Static IP will cause the applet to say Not Connected (as everyone has experienced already)
- Even when Using DHCP, NetworkManager Applet works randomly, sometimes it even says there are no network devices.
- ifconfig reports that my eth0 interface has been properly configured via DHCP.
- I can ping to any IP address successfully.
- Cannot ping to a hostname.

Could it be that the dns-client service (or whatever it's called) is not being re-initialized properly?

Rebooting the system will make it work again.

I hope this information helps.
