knetworkmanager doesn't work; Evolution and Firefox start offline ?

[linux guy]

I'm running F13, fully up to date.

This morning I encountered a number of problems.

1) Evolution starts in "Offline" mode, ie it doesn't think there is a
Network connection and there is now way to put it online.  Thus I can't send
or receive emails with it.

2) Firefox starts in "Offline" mode, but I can set it to being online and
then it runs normally.

3) knetworkmanager won't run.  Nothing happens if I start it from the
command line.

Anyone else having similar issues ?

Any ideas on how to trick Evolution into thinking there is a network
connection ?

Thanks
