For several days now my new Surfboard SB6121 reboots all the time, sometimes as frequently as every 10 minutes. The message in the log is always the same: "Cable Modem Reboot due to T4 timeout." What would cause this?
In case it may be related: I recently had a service outage that was repaired last Thursday. The problem was at the pole, not with the modem, but while the tech was here I swapped out my SB5101U with the SB6121. Then the constant reboots started.
