Customer Ratings & Reviews

So I bought this modem because I just upgraded to Comcast gigabit internet. It would work for a short time (sometimes 5 minutes, sometimes an hour) and then it would just stop. All the lights go off on it. I thought it was a faulty modem so I exchanged it. The next one I got did the exact same thing. I had a Comcast technician come to my house and he told me the modem is no good. I can only conclude that everyone of these on the shelf was bad. This time I exchanged it for an Arris SB8200. That one works like a charm with absolutely no issues. I would steer clear of this one.

NETGEAR - 32 x 8 DOCSIS 3.1 Cable Modem - Black was OK for my house.

Opted for an Arris modem. Will consider once DOCSIS 3.1 is adopted by ISPs

I bought this to upgrade. I was having problems with this also

modem only connects at 20-40 download speeds , Not happy at all as a best buy customer.

I have a 1gbps with xfinity but only seing 815 Mbps. That's not good

Instead of renting a modem from Comcast I decided to buy one. Everything I read said this is compatible with Comcast. I was having trouble getting Comcast to recognize the modem and called their technical support. When I gave them the model number, CM1000-100NAS, they said it is not compatible. I don't know if this is just in my area or not.

I "upgraded" from a DOCSIS 3.0 to this...only to have it repeatedly drop offline. I've got 1 gbps internet with between 6 and 20 ping...so there's absolutely no reason for this modem to disconnect/drop between 4-8 times a day. I troubleshot ever part of my system, from cable through mesh, then reconnected the old modem and have had no disconnections for four days. Not impressed with Netgear, and going back to Arris.

The Cm1000 modem paired up with the Ax8 Router by NETGEAR is a must have for Blast and Gigabit speeds from Comcast (Infinity) Delivers amazing wifi range and speeds

One of the worse modem this is. They just have the false information. Never reached the capcity, maximum was only 180 mbps. I talked with netgear represemtative so many times and they never sorted out my problem.just wasted my time.

the salesman was wrong on everything he said. if he is the only one in the store I will leave.

Decent modem no complaints about it so far works great with my eero

Modem went out after 5 months and NETGEAR’s horrible customer service refused to replace it. I already had to do a factory reset on it multiple times before. But because the lights were still on they said it works fine when it has only had problems since I’ve had it. Even my ISP tried to fix it and couldn’t. And they still couldn’t get it to connect to the internet. Eventually I just used a different modem and now everything works fine.

Took a while to setup had to use Comcast to connect. Took about 45 min to connect. Its been solid after setup Comcast was very helpful working with me. Netgear needs to improve their online setup procedure, otherwise its all good.

Replacement was exactly what i needed. Interest repsonds well.

I returned this because it didn’t work with my cable connection. Probably a very practical, reasonably priced router. Return was very easy.
