Home Networking Problem

For about 2 weeks now, my home network (for lack of a better description) has been locking up on me. The network seems to just disappear as none of the computers can see each other or access the internet. Unplugging and resetting the switch gets it going again. I have a completely wired network, nothing wireless.

I?ve replaced the switch 3 times with different models, no improvement. I swapped the cable modem (Charter Cable) for a new one, no improvement. I tried 3 different 4-port routers, no improvement. Last night, I picked up a new 8 port router and eliminated going thru a switch, it still does the same ?lock up.?

I have 6 computers and laptops connected to the network. All are running Folding@Home 24/7.

Anyone have any idea how to trouble shoot this? In the back of my mind, I?m wondering if it?s Charter Cable doing it because I have 6 machines attached? Better question, how would they know anyway since I?m behind a router?

Thoughts, comments, suggestions? Thanks.
 
How often do you lose access to the network, and does it always happen to all computers at the same time?

When this happens, do the computers lose their IP address information? (use IPCONFIG in a Command Prompt to find out)

If they don't lose their IP information, are they able to PING the router? Or the IP address of another computer on the network? If you can PING the router, can you PING www.google.com?

Are you running anything on the network other than Folding and regular Internet browsing? P2P/file sharing applications, for example...?

 
All of the computers lose connectivity. It is as if something's wrong with the switch because both the router and cable modem appears to be fine. I've replace the switch 3 times and even completely eliminated having a switch by buying a 8 port router. No P2P sofware is installed on any of the machine.

It seems to happen intermittantly, once I reset it manually, it runs sometimes for hours and other times only minutes before locking up.
 
Sounds like a possible cabling problem.

See if you can ping the router or other machines as instructed above. Have a constant ping going on one of the computer "ping 192.168.1.1 -t" or whatever your router's address is.
 
Once it's "locked" you can't ping anything. This affects all computers. I'm going to try replacing each cable one by one. I just hope if it is a cabling issue, it's not one of the ones in the walls of the house.
