Why does my DSL modem 3360 suffer from not wanting to go online and freeze ups.


Contact ARRIS for Consumers if you bought it retail. If you got it via AT&T they should take care of warranty support.

We have an Arris wireless modem. We have lost the adapter that goes with it. My husband purchased a Belkin Wireless adapter, but it would not work. We went back to the same store and they do not carry...


If you meant you lost the power cable, then you should contact Arris to buy it.
If you mean you lost your router that was hooked with the Arris modem, the you can buy any router for house like D-Link, Linksys... and get it configured to work properly with the Arriss modem where you buying at.

Problem with my Arris Comcast cable modem.


I just had a tech out yesterday regarding this problem on a TM402 - restarts under high network saturation (big uploads or downloads). According to the tech, this is a know issue. Comcast upgraded their network to support multiple carriers (called channel bonding) dynamically. Due to this upgrade, when your modem is demanding high bandwidth for large downloads, essentially, it requests an additional carrier (or channel)...when that request is initiated, the modem's hardware (and firmware) can't connect to more than one channel at a time, therefore, it "gets confused" and restarts itself to attempt to fix the problem. I upgraded to the TM602, and the problem is still there. This is because the channel bonding feature requires a Docsis 3.0 capable modem. The Arris TM702 is the first in the Arris line to offer docsis 3.0. I called Comcast and they are upgrading me to the Arris TM702 (which is a 50M down/10M up service, btw) for an additional $30/month - well worth it for the stability which I require.

As far as Comcast saying that it's fine, call them back with the information I provided, and ask to get you to a tech who can better service your needs...unfortunately, the "tier 1" techs don't have a clue.

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.

No driver for my modem


There are no drivers for the arris cable modem unless you are using USB.

If you are using ethernet then it is simply plug and play. You may need to press the reset button on your arris.

Thank you.

Connecting my arris modem to x-box live


I have an Arris cable modem and use Xbox live. They work very well together. Most ISP's will only allow one active device at a time. When you switch between you cable modem and your Xbox you need to use a pen and press the reset button on the arris every single time you switch.

Pulse-dialing with Arris modem?


If you have the current firmware for your modem, it should work with pulse. Arris had to make it's MTA's pulse compatible due to old alarm systems that still utilize pulse dialing.
