Possible NetworkManager problem, but where to look?

My wife's laptop has started having interesting networking issues.
She's connecting to a WPA2 secured wireless AP.

All networking communications work fine right after boot, but at some
point all connection attempts TO her computer fail, while all
networking communications coming FROM her laptop continue to work
fine. I have tried disabling the firewall but it has no affect.

Failure Observations:
- Auto-discovered printer queues drop off
- Can no longer ssh to her machine
- nmap -sS hostname can't find that she even exists. This would be
GREAT if I wanted to be stealth on a network.

Currently the workaround is to restart NetworkManager which
temporarily fixes the problem. I'm not ready to say that NM IS the
problem as it could be something else, such as a buggy driver, that's
the root cause.

So where do I start? OS is Fedora 13 x86_64 fully updated. (lspci

Thanks,
Richard
