BNN, try this.Look on the modem itself or download the user manual and see what it says are the power requirements. For example... 12 volts at 2.5 amps. Next unplug the plug in power supply (aka "wall wart"). Are they the same?I just purchased a nighthawk cm1100 and the paperwork says it needs 12v 2.5amps but the supplied power supply is only 1.5 amps. Will it work at 1.5 amps, probably. But it is starting out right at the threshold. As it ages, the voltage could slowly degrade which equals lower power (power=volts x amps). In my career, I delt with low voltage devices and had to replace countless wall warts (to many to count) that looked like they were working, but had actually degraded and were causing weird problems. I just read online about a guy who was also having modem rebooting problems and he replaced the 12 volt p.s. and all his problems cleared up. It is worth a try for all of you out there having this same issue. I was shocked to see that my new modem had an undersized power supply right out of the box.
