As we all use computers here, we could all occasionally benefit from an rsi 
time out. :}

Assuming you shut the machine down last night after the net stopped working, 
_perhaps_ it would be useful keep track of what the room/computer temperature 
and uptime is each time it stops working (from a cold boot) ... It could be 
that a component is getting hot, or saturated in another way that has a 
hysteresis curve.

Did you also shutdown the router last night too?

Have you done anything to see if someone else may be attempting to use/abuse 
your router, like look at it's recent IDS logs?

Might try transferring a couple of fedora install DVD isos across it into 
/dev/null, or some other throw away storage on the machine, to see if it can 
only handle so many bits before needing reset.

Just ideas.
