XR500 always rebooting

I have tried installing the old hot fix for drop out and it is still occuring. Happened after the latest firmware update. I have factory reset more than 5 times and have setup the wireless from scratch each time. I have created new and different SSIDs, tried multiple solutions found in the community- is the power adapter connected ok, is it plugged directly to an outlet, to reboot the modem each time I reset and reboot the router, i changed the Cat5e cable, etc.

None of these solutions have worked to solve the issue. The drop out even occurs after factory reset after some time. It will work for a little while without dropping out and then it will drop consistently after that first time. Intervals are sometimes 10-15minutes, sometimes 1-2minutes apart.

I am using CM700 with a Cat5e cable, no other hard wired devices connected to the router. I have left the defaul factory settings for the router and it still causes drop outs. 

I am currently on firmware .66 because the dropouts are much less frequent than with .114

I have also tried the hotfix patch that was on the forums not released, and the drops still occured.

Please assist!!!
