At a loss....

So I was one of the ones that got the Moto sbg6580....was having horrible issues where everything would be cruising along, and then just stop, complete packet loss. Thinking it was the modem I gave up on the sbg6580 and ended up getting the linksys e3200 wireless/router and the cisco dpc3008.


Same thing is happening. I have the blast package with TV. Wife and I will be in the living room watching TV she will be on her laptop, I will be on mine. All of a sudden nothing, quick ping to the e3200, bing bing bing works fine, quick ping to the modem, and get timeouts from the modem. I jump to a computer that is hard wired to the e3200, same thing pings to the modem timeout, after a few seconds, its back. From what I have been able to catch it doing is. One time upstairs, internet dropped (tv continues working fine), i ran downstairs looked at the modem, and it was like it was just rebooting. 


Tonight I am going to try a different coax cable, and maybe a different location. Besides that are there ANY ideas out there, I have tried everything I can think of. 

Below are the line specs from the modem status page.
