Question about Arris Touchstone 450a (CM450) Modem

Re-starting a ARRIS modem after a loss of power

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.

Can't connect to internet through router wired or wirelessly Belkin N750 F9K1103 after ISP dropped out for one hour


Unplug the ISP modem completely, power, and cable. There might be a recycle (a quick push) on the modem as well. Some modems have a battery backup and will stay lit, if not connect the power, reboot and then connect the cable. The modem may take a while to fully reload after reconnecting. Then do the same with the router. Only do a quick push. Holding it in will clear custom settings on the router.

You should have green on both the modem and the router now. If not you have this to inform the ISP of your troubleshooting. GL

There is no internet connection to the laptop. The arris modem gives internet acess to the PC computer, though. The manual for the Airlink 101 router says to connect the router and MODEM to each other by a...


What you're missing is that ALL the PCs will be connecting THROUGH the router to the Modem. Unplug the PC network Cable from the modem, then plug a network cable from the router's INTERNET port into the modem (where you removed the PC's network cable). Now, plug the PC's network cable into one of the ports on the router (usually 4 or more, marked 1,2,3,4. Think of a Router as a "splitter". It connects to the Modem, then several devices connect to the Router, some of them by wire and some by Wi-Fi. So your desktop PC is connected by wire to the router and your laptop PC is probably connected by Wi-Fi (wire is an option, as well). The Router sorts out all those signals and communicates with the Modem. Sound reasonable?

That won't work because your old sbc wireless router 2wire gateway is also a modem. You need a plain router for Time Warner. Try Linksys router.

CHEC


do a hard reset on your router, and try again. After the hard reset plug your modem into the router but disconnect the power and reconnect the power after 10seconds. Other than that, Dlink tech support should be able to help you solve the problem.
