Modem keeps rebooting

Bought CM400 March 2015.  Stoped working August 8th 2015.  Have comcast as internet provider.  They sent tech out to assess situation.  Re-hooked up the CM400 directly to laptop and to wireless router.  Summary of visit:  CM400 modem just keeps rebooting every few minutes.  Unable to keep internet connection.  Swaped out CM400 with comcast modem and connection is fine.  The coaxial cable port is a bit loose - could that be the problem?  If so how do i go about getting the modem replaced as an $80 item should last more than 6 months.
