Question about Arris Touchstone 450a (CM450) Modem

1 Answer

Can't get Arris Touchstone modem on line after moving house. Haven't tried to hook up to (same) ISP for over two months after moving, but I doubt if that is relevant. LED indicators, after power up, show Power ON and DS (both continuous green) but US keeps flickering (third LED from the top) and nothing after that. That's as far as I get. Funny thing: my OXX Internet Radio set does pick up my LAN SSID but can't connect to any Internet radio station. Of course I've tried re-setting the bl**d thing but there's not much else I can think of. Anyone any ideas?

There is a filter in the cable line somewhere not letting signal get out- if you know where all the cable lines come together you will probably see a little filter on one side of the splitter- the line going to your arris modem CANNOT be behind the filter.- If you are not aware of where this is- then you will need to call a cable tech to come out and do it for you

My arris CM550A modem has all lights on but the link light is not blinking.wether it is connected to a router or to a computer there is no change. my isp also confirmed there is no disruption in service


As long as the modem is passing its data then i wouldn't really worry about the light not blinking. If you cant access the modem or it wont sync with a solid link light, then you have issues.

You should use a router, but if you cant, try hooking everything up like normal, then pull the power cord on modem for 10 full seconds, hook back up, wait 5 minutes and then try.

Lost dial tone and phone service


Your phone line might be connected to Telephone 1 not 2. That could be the reason why you are not getting a dial tone.

Free internet?


Yes, You need to contact your a local cable company and sign up for service. Tell them you own your own modem and you will need to give them the HFC Mac address. Once they enter you into the system and your a paying customer everything should be smooth sailing.

Need solution to Networking 2 comps thru an Arris tm602g/ct via a linksys 8 port switch, the seems to be no Usb connection on the modem


You will need to purchase a router my friend. The arris does not have a DHCP server built in and cannot assign IP addresses to the work stations. The only way that could work is if you ISP provided you with a second IP address, which would also be extremely unsafe from a security standpoint. Any wireless router should do the trick.

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.

Telephone dont work


That light is indicating that you have a phone off the hook, a short in one of your phone lines, or a bad modem. Unplug the phone line from the back of the modem. If it stays solid, plug it back in and go and disconnect every phone in your house. If it stays solid you have a phone issue. Plug them back in one-by-one and see which one causes it to start blinking. If it doesn't go away after unplugging all your phones, you have a phone line issue. If it is still blinking after unplugging the phone line from your modem, your modem is bad.
