Internet drops and Surfboard modem keeps rebooting
I am experiencing frequent drops in my internet connection with a Motorola Surfboard SB6141. From what I understand, the signal strength seems in spec, but the modem logs show frequent rebooting. I am not entirely certain that the reboots correspond to when the connection drops, but they do seem approximately related and I am certainly not rebooting the modem myself. The reboots are also strange because the drops usually will recover very quickly, even within 5-10 seconds, which doesn't seem like a normal reboot. Any help would be appreciated.

These are suspect. So you are not physically / manually doing these power-cycle operations ?
