    The performance was great for the first 36 days, then it stopped working totally. I had to get a replacement from Motorola. I hope the replacement unit will last longer...

    Not impressed in the slightest. Xfinity services cuts out, xfinity reports zero outages, lose internet randomly. No available firmware update. Device power cycles on its own.

    Salesperson sold me wrong device. Needed to be modem/router. Went they trouble of setting up and determined it was wrong. Not the products fault. It was bad situation with salesperson and rehab work at Beat Buy that prevented us from going in and shopping for ourselves. Disappointed in sales staff. I thought he knew what he was talking about. Ow I need to return item. I had to rent one from Xfinity.

    I purchased this modem and significant issues with it unable to stay connected to internet. When I checked other reviews, people had similar issue and one of the remedies was to search for splitters within the cable line. I needed to be up and running for work so went with another router that has not had any of the same issues. I think this may be an issue depending on your cable.

    I would recommend the Arris modem. I purchased this Motorola modem and had numerous problems. The modem would reset itself 3-5 times daily and would cut off my internet access for up to 10 minutes each time. I returned this modem and bought the ARRIS modem

    This does not work with Xfinity. I threw away the box before I discovered that. So I have to deal with motorola support. It's been a month now of them sending me emails telling me I need to respond. I've responded by phone and email each time they asked. They are just stringing me out. DO NOT BUY THIS PRODUCT.

    If you buy tgis modem DO NOT UPGRADE YOUR SPEEDpast 100mbs. If you upgrade it it will download an incorrect boot file in yhe modem causing it to constantly reboot. Also the tech support is non existant. They dont answer, leave you on hold for about a hour and leave you with a defective product.

    Maybe got a defective product. At first it stuck at ranging in progress for nights… Then finally online, it keeps dropping connections with my router. Returned and changed to a netgear modem setup in 5 mins works great.

    Multiple disconnects of internet connectivity per day. I would see the modem lights go dark and then light up as if the modem was restarted. Very frustrating for an almost such an expensive modem. I'm returning within the return period.

    Worked great...for three months. Bought on 4/4/2022 - the Ethernet port went dead 7/18/2022. Yes, still under warranty but can't wait for a replacement so had to buy another modem, NOT Motorola.

    I bought this assuming I’d be saving on my monthly comcast bill, but in fact lost features, lost unlimited data, and was charged more per month to use this modem.
