Query: Causes my cable modem to restart frequently

I was disappointed after using the Netgear MR814v2 for more than a week to determine it causes my RCA cable modem (supplied by Comcast) to unexpectedly restart, losing my Internet connection, and to degrade the connection speed when it does work. The Netgear firmware upgrade did not resolve the problem. After going back to my non-wireless router, the Netgear MR614, all is fine and my cable modem no longer restarts unexpectedly. Comcast confirmed this is a problem with some routers. I didn't believe it at first, but after a week of troubleshooting I believe it now. I have always been a big fan of Netgear until this situation. I am returning the MR814v2 for a different brand and model of a wireless router.
