Question about Arris Touchstone 450a (CM450) Modem

1 Answer

I have an Arris modem from Comcast that gives me phone and internet service. Prior to going to Comcast for telephony I used a regular, off the shelf, modem and I could connect to my Direct TV sat box via an ethernet plug in and download shows I missed via the internet. Since getting the Arris modem I can no longer get my sat box to recognize the internet. I tried to connect directly to the modem and still no dice. Any ideas? I have rebooted and disconnected until I'm blue in the face and get no help from Comcast.

Comcast use 10.0.0.1 for ip address, I think
check direct tv box for internet settings for it's ip address should 10.0.0.2 maybe call directv maybe they could further.

SOURCE: Arris Modem connected to Mediacom Service

I didn't have incoming calls for a year (didn't mind, no telemarketers). But I fixed today.

Check with your home alarm company. Turns out they can download a signal. No, it wasn't the computer's internal modem, it wasn't the phone/cable company or the arris modem.

No need for service call.

SOURCE: Arris Modem won't work with Airport Express

Not sure how helpful this will be, as I'm running a different piece of gear, plus it requires both troubleshooting + ISP assistance.  I had a similar problem with my AirPort Extreme: AirPort Extreme saw the Arris, iBook saw the AirPort Extreme, but no internet connectivity.

  1. In my case, I needed to set the AirPort to DHCP in the AirPort Utility application.
  2. Power down the AirPort Extreme
  3. Power down the Arris. You achieve this by unplugging the Arris *and* removing the back-up battery.
  4. Wait a few moments.
  5. Insert the battery into the Arris.
  6. Plug in the Arris power supply.
  7. Wait for the Arris to go through the restart protocol; when all the lights on the front panel are solid green, the start-up is complete.
  8. Power up the AirPort Extreme; wait for the front panel light to go solid green.
As I was doing this, I had my ISP on the phone that confirmed complete connectivity of the signal path and ensured that I was online.  While the Arris was powered down, my ISP also sent a "message" to the Arris; I don't know if this was a software update or what.  I completed the AirPort set-uo through the Utility application, the AirPort restarted, and I was online.
Hope this helps.

SOURCE: Unable to set up wireless router

Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

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?

Setting up xbox live


ARRIS modem is a phone/hsi modem. What youll need to do is first turn power off on xbox then unplug the power supply from the back of the Arris modem and unscrew the coaxil/cable wire from the back of the modem for about a minute. Then plug in the power cord to the modem wait another half minute then screw in the coaxil/cable wire....wait for the lights to come back on make sure the online light is solid green not flashing and follow the ethernet cable (Looks like a thick telephone wire) and make sure you have that ethernet cable seated/snapped into the ethernet port on your xbox. Then turn the xbox on and do connection test. FINISHED..IF it's still not working make sure you have Internet service from your provider and if using a router bypass it at first see if you can get onto xbox live without the router. If you can with just connected directly to your arris modem without the router involved. If you do want to use wireless contact your router manufacture and or xbox support at 800-469-9269.
