Unhappy Network disconnecting, requires reboot to restore.

First I'll describe my setup, then my problem

I'm connected to the internet via a cable modem, it is connected to a wifi router that has many 100mb ports. Those ports are connected by cat5e to a hub where my wife and I split off and take internet via dhcp with ips of 192.168.0.4 for me, and .5 for her.

on occasion, my internet will drop out and the only way I've found to return it is to reboot fedora 7 to restore Ethernet. if I try system-config-networking, it shows the ip active, but I can't ping anything in a terminal window. if I disable my eth0 and re-enable it there, it will sit there and never get dhcp out.

the oddity of this is, my wife can ping and browse no problem she's on a windows computer.

there's no ip conflicts, and I'm not seeing any errors occur, applications crashing or anything.

how do I monitor this to figure out where to start looking to find out what's wrong?

any suggestions?

Id also like to point out, that sometimes, the connection will drop out in the middle of the night, and upon return, I have resorted to rebooting to restart the entire system to get everything to work again.

Even if it's not the answer to your question. this will restart your network services without that annoying reboot:

/sbin/service network reload

tried this on several occasions and still had issues. something is crashing internally and I got no way to know what it is.
