Customer Ratings & Reviews

Do not buy this item. It failed 8 weeks past the warranty expiration. Extremely disappointing.

This went out less than a year. Don't waste your money. They will not fix it

What an absolute piece of crap! Completely failed after just over three months of use!!!

Bricked up after unplugging once to move things. Worked fine before

Unit die: after only 4 months - disappointing considering the price.

I’ve purchased another because the first one peetered out and now the second one.

Garbage. This product did not do anything or was an upgrade to my exising modem.

Bcm3390, same as MB8600, MB8611 Just look's different .

Not compatible with Xfinity I recommend mesh routers only

Went bad after 3 months of usage, wasn’t happy about that

Didn’t do anything to improve speed or performance

CM2000 works with Optimum or Suddenlink in Austin TX. I have a 400 mb down / 40 mb up plan and it exceeds those figures. Provisioning was easy, the modem can be logged into & it's been working flawlessly. It is an odd shape and puts off a little heat. Definitely not cost effective for my current needs nor is Doc 3.1 necessary today.

I was looking for something that would have > 1GB port (this one has a 2.4GB port) and could support speeds > 1GB. This fit the bill, getting about 2.4GB out the back side. It's a lot of money, but the number of devices that actually have a port that can support the claimed multi-gig speeds over a wired connection are few and far between.

From set up to operation, our Nighthawk CAX80 is flawless. One of the easiest modems to set up out of the box and the most reliable when it comes to running multiple data hungry devices. We have tried many other brands and now that we have purchased and used a Nighthawk modem/router, we wouldn’t use anything else. Finally, a reliable, easy to use, modem router that provides excellent coverage and speed at a decent price. Well done Netgear, well done.

Looks great, works great, better than the equipment from Xfinity. Setting up with Xfinity was a bit of a challenge, their systems are pretty awful, but when it finally connected, it works fantastic. Works perfectly with a Nighthawk router, solid products.

This device is blazing fast. Before you think to bash this product for subpar performance, make sure it is not induced by your ISP provider. Mine was Cox cable and I kicked their overpriced cable service to the curb and switched to online streaming. Well, the cable co. installer installed a 1 to 4 splitter that actually caused this modem signal to noise (SNR) numbers on all 45 downstream channels to be below minimum performance levels. This caused a gigablast service to operate at 130-ish mbps DL speed. Once the spliiter was removed, modem restarted, SNR numbers exceeded SNR required levels, downstream channel light stop blinking, and DL speed is consistently 940-955mbps. Of course, Cox text support could decipher this problem and they considered SNR of 27-31 dB as acceptable. To their credit, this device is on their approved list for gigablast service and they manage the firmware for this device very well. Netgear has outdone themselves with the CM2000 device and also the ORBI AX6000. For my situation, the monthly savings in cable bill and no equipment rentals fees will pay for this device in 8 months. So worth it!

Easy device setup (less than 10 minutes with existing hardware). After a month of ownership no issues to report. I paired this Modem with the RBK852 Orbi Mesh System and am consistently able to achieve 1300 Down and 45 Up from my ISP.

I bought this to replace my cm1050 modem. Xfinity essentially disable the 2-4ports on the cm1050 and customer service is clueless sbout how that works. After realizing the modem only gets me 800mb at beston my 1200gb plan, i decided to switch. I picked up this cm2050. Works like a charm, i hard wired my laptop and was getting well over 1000gb. I mated this with a netgear ax5400 wireless router. My wifi speeds on my laptop peak around 900mb abd i get between 500-700mb on my cell phone wifi signal. Ive got 37 devices connected to my network and this modem is piping all of the internet in our home wonderfully.

this is a good modem and reliable. I just am not sure if it is much better than a different brand router and I could have paid a lot less. I recommend it but it may be over priced.

Speed is great, set up was simple. The proformance went beyond
