Losing internet connection every 3 hours, SBS 2008

For the last few months I have been consistently losing my internet connection intermittently throughout the day, every day. Here's some details and things I have figured out so far.

-HP Proliant ML350 G5 intel dual quad core
-3 network cards, only one enabled
-single server, about 30 clients
-DHCP being run from SBS 2008
-WRVS4400Nv2 and/or WRVS4400N routers
-SBS 2008 fully patched and up-to-date

Almost every 3 hours I lose my internet connection. All internal network connections still work, client to client, client to server, etc.
-Rebooting the server does not restore the internet connection.
-Rebooting the modem does not restore the internet connection(2 different modems tried)
-Rebooting the router does restore the internet connection(i have 2 different routers)

When the internet stops I cannot release or renew my ip on the router. Replaced the modem and router and the problem still occurs. Started about 3 months ago. The loss of internet, while frustrating, is less of a problem than disconnecting everyone from the server for the minute or so while the router reboots.

I have tried absolutely everything i can think of the fix it with the exception of a re-install to keep the internet sustained, but to absolutely no avail. Any ideas at all?

Have you called your ISP and bitched at them - you have ruled out your end of the equation and that leaves the ISP.  Get on the phone and get them testing.  Don't get fobbed off with "the problem is at your end".
Could be noise on your line - could be a fault on the line.  Could be phone exchange hadware errors.  Could be system erros on their systems.
Everything you have done and replaced points to the ISP / phone line in my opinion.

I have not phoned them yet. Its the timing that makes me still think its on my end somehow, the time between reboots of the router is always 3 hours and 2 minutes.

Multiple phone calls today resulted in a fail. I have their tech "team" apparently coming in tomorrow to look at it from the inside, but they did admit that they have something on a 2-3 hour cycle.

Oh well - that's good enough for me to point the finger nicely at them ;-)
I am guessing you will know more tomorrow so no point me speculating more now about what it could be, but sounds very encouraging.
Glad you made progress - that's a feather in your cap for getting that far, considering some ISP's I know.

So the phone tech showed up, said that we had been(unbeknownst to us) given a refurbished modem. He replaced it and and checked the phone lines etc. The internet still was going down until.....magically the next morning the internet was working and has been since. TELUS FAIL.

Thanks!
