    Good for use ONLY if you don't need WiFi because it does not have that capability.

    Did well for two days but then failed. I thought it was the new router and exchanged that, but still problems. We changed the port used and that worked for another few days, but that port failed also. Returning.

    The unit disconnects daily, Arris tech support couldn't fix the problem, I returned the unit to store and got a refund, I hooked my old Netgear cm500 and it is now working fine, no disconnects. I heard problems with the Intel Puma chipset in these modems, disconnecting is one of them

    Had this for a little over one month and it started dropping connection. Spent many days without internet troubleshooting with both Comcast and tech support. Warranty does not provide advanced replacement. This product has known overheating issue yet they still sell this product. This modem is junk with horrible customer service.

    It took 2 hours for Xfinity to proviso the new MODEM. We pay for and Xfinity says that we are getting 900MB but a number of speed test show we are getting only 150MB.

    It is okay. There aren't many cable with voice modems. I purchased it - set it up - and did look at some of the details on the box it has a number of limitations where you probably are never going to max it out. I returned it to get a Netgear that was much less expensive.

    Be cautious if you buy this modem. I bought one and tried to add in to my account only to find out that the MAC address had already been used in a different state. Took it back to Best Buy and exchanged it for a new one. This one the serial number was used on a different modem. Not sure what ARRIS is doing with their modems but they do not work

    I can’t answer if it’s a good product. Had to return it, it doesn’t support Wi-Fi. Best Buy employee gave us the wrong advice.
