Purchased Mar. 2021 and haven't had any complaints. Gets above rated download speeds when I speed test it. Great performer.

It did its job for two years! Good signal. My family use it for streaming movies and children use it to play online game (like Roblox, not very demanding game). I had an old one which worked for exactly 2 years. Power surge in a lightning day damaged it. I live in the southern Georgia and there are a lot of lightning in summer. I do not turn off the previous modem and it survived many lightning until the recent one. I like its price, ease of use, and durability. Therefore I bought the same model again without much thoughts.

Do NOT buy this as your Comcast modem. It is only $20/$30 cheaper than something that will work 10x better. The modem worked fine until the COVID pandemic. That’s when I learned first hand why all those channels matter. This modem only has 8 channels to try. I can’t get support or a warranty since this drops signal constantly. Xfinity came to my house and tested from the telephone pole to my router. The modem was the only weak point. I asked the guy what he has in his house and why. He has an Arris Surfboard 32 or 36 channel (can’t remember exactly) and it works way better.Pros:$20/30 less than a good modemWorks in light use environmentMinimal restarts.Cons:No support at allOnly 8 channelsWeakest point of my networkOnly worked for 6 monthsUPDATE: I ran this modem for only about 6 months. At the recommendation of my internet provider I replaced it with the modem he recommends. My internet has never been more reliable. This can 100% ruin your internet.

We recently upgraded to 200 Mbps internet speed and my old Arris modem couldn't handle that speed. So I decided to try out Motorola for a change, based on its good reviews, plus it was several bucks less than a new comparable Arris.Turns out the Motorola works great. Easy to hook up, after which I just needed to call my cable company (Wide Open West a.k.a. WOW) for them to activate the modem. Once done, this thing flew! I consistently pull 200+ Mbps down on it.(Regardless of the box saying "343 Mbps maximum speed", really this modem is perfect for my 200 Mbps internet package. It's certified by Comcast for 200 and WOW in my area subleases Comcast's network. Looks like Charter and Cox certified it for 150 per the graphics in the product listing.)One last thing: Some cable modems get hot, but this one is just warm to the touch and not hot at all. I don't foresee it having an issue overheating. It has plenty of ventilation on the sides and top.If anything changes, I'll update my review, but for now, this modem seems like a solid purchase.

I purchased this modem along with a new dual-band router to replace a Motorola (Arris-made) SBG6580 gateway, which had both a cable modem and router integrated into one box. After adding a number of Amazon FireTV sticks to my TVs, the SBG6580 started locking up, requiring a hard reset. The SBG6580 was 8 years old. I suspect the numerous wired and wireless devices was overloading the NAT table and memory of the router portion and locking up the unit.I decided to go the separate cable modem and router path. This modem has been great! It has 8 downstream and 4 upstream channels, the same as the SBG6580. My internal Ethernet wiring and switches are currently optimized for 100Mbps. My Comcast plan tops out at 75-80 Mbps, a good match for the hardwired Ethernet capacity. This modem is more than capable of handling that speed. Upgrading to more downstream channels or a DOCSIS 3.1 unit would be wasted capacity for my situation.Just a note of caution. Arris is the company that purchased the Motorola division that made cable modems and retained much of Motorola's engineering talent. Arris abandoned the Motorola branding, which was picked up by Zoom Telephonics. Zoom is the company making this modem. The quality is still very good, but don't try calling Arris for support! When I added the modem to my Comcast account, it showed up on my account as a Zoom Telephonics device, not Motorola. I called to correct this, as I wanted to be sure they pushed the correct firmware updates to the device. They confirmed that it was correct. Just saying, if you catch those little details like I do,When Comcast sees a modem with a different MAC address, any browser routes to their self-activation page, where the replacement modem can be set up by the end-user. Not realizing this, I called Comcast. It probably took longer doing it that way, but in the end it came on-line without a hitch and has worked great in combination with my new dual-band router. The SBG6580 crashes are gone, but I kept it to use in "bridge" mode as a backup modem. The crashes likely only affected the router portion of the box.The unit is quite attractive and has a real power switch near the top of the case back, making any rests quite simple.Highly recommended!

Overall product works as advertised. However, I found out the product I ordered advertised as new was actually used and had previously been registered with Mediacom and associated with another person’s account. After two different lengthy calls on the phone with Mediacom, I was able to remove the registered device from the other person’s account and register it with my account.The WiFi signal is great and far better then the rental option Mediacom offers. I was disappointed however finding out it wasn’t new. Other than that, I would recommend and would have given it 5 stars.
