Question about Arris Touchstone 450a (CM450) Modem
After the modem lost power, it refuses to re-connect to Timer Warner Cable's network. The little power light is on, but none of the others are. I have tried (a)disconnecting and re-connecting all the cables and (b) resetting the button on the back, but no joy. TWC will come out to "fix" it, but in the meantime I'm without internet and telephone for 5 days.
You can try doing a "Hard reset" on the modem but it looks like you've tried most combinations. To do the hard reset: - unplug the coax cable from the back of the modem - Push and hold the "reset" button in for 15 seconds - Allow the modem 30 seconds to reinitialize and then plug the coax cable back in. Within 10minutes you should have activity back. If not, the modem needs to be replaced. I know you may have tried something similar to this but I'm hoping this may help.
