Easy replacement for old modem
I purchased the modem after getting an end-of-life warning for my previous NETGEAR modem -- and a nice discount. It was literally a drop-in replacement. Moved the cables over, gave Xfinity 15 minutes to provision it, and I was back online I'm getting about 150mb/s more on speedtests with the new modem than I was with the old one.

Fast and Easy Setup
The Netgear CM1000v2 is very easy to set up. The instructions included with the product are clear and helpful. After providing the serial number and MAC address to my service provider, activation was quick and seamless. I ran a speed test afterward, and the results were impressively fast! I’m very happy with this cable modem — it’s reliable, fast, and a great value ...

Needed a quick replacement, working good.
We work from home, the old modem got sick so we pick this one up. Easy setup and good speeds both up and down.

NETGEAR modem
We needed to upgrade our modem as internet speeds are increasing. NETGEAR is perfect for us and our internet works perfectly throughout our home. I recommend this product.

Very helpful and pleasant
I bought an hooked up to the Netgear 13 equipment. Contacted my provider for their hook up. Waited for system to link , then verified with a call to Netgear for their account verification and all is good. I only did this per my provider to help in dropping the cost on my monthly billing from Asound broadband.
Thanks

Good while it lasts.
Worked great for exactly 3 years. I wonder sometimes if items like this has a built in ticking time bomb to just go after a certain time. Worked well with the Netgear AX5400 Nighthawk. But I'm skeptical wondering if that doesn't go next cause I got that a month later. LOL.
