I've been having on going speed issues with Comcast and trying to find out the cause. My service gets extremley slow at times, so I restart the modem by unplugging it and plugging it back in. I exchanged a broken modem with Comcast a few months back for a new Cisco DPC3941T, which takes 10+ minutes to restart. Is this normal? I know it was with some old Comcast issued modem/router models from forever ago, but i'm not sure about this one. My previous modem was much faster at rebooting. With the Cisco, once I plug the power cable back in, "power" is the only thing that lights up, for about 5 minutes. Then slowly but surely, everything else lights up and the internet comes back on. Takes roughly 10-13 minutes to get everything back up after the power cable gets plugged back in.
Is this normal? Could a cable be bad? Semi fried modem?
