NETGEAR - Nighthawk Mid/High-Split DOCSIS 3.1 Cable Modem - Black

Customer reviews

• I replaced my rented modem.

  I have been building a homelab for a year or so and have been getting my own infratructure without renting and it gives me the speed I need for all my machines. Video games download at about 400-600 mbps.

• Better than service provider model.

  Was tired of the monthly fee for the device provided by the ISP. Would have ended up paying for 3 of these over time since time of purchase. Paired this with an Orbi, great combination.

• Cable modem setup

  Got the correct app straight away setup was easy. Any problems I had with Internet service was my ISP problem not the device which was selected to be compatible with their systems.

• Not Compatible with COX

  Bought two of these, one did not even connect (returned) because cox said it was bad, the other connected but will drop every minute. Firmware was updated, multiple power cycles and check of connections and multiple calls with tech support from cox and Netgear and nothing. Both would blame each other. Had a technician come to my home check all coax lines because they thought it was that, so I was out money on that and no success. I ended up returning it. this is a joke of equipment with COX setup.

• Great modem, but check your signal levels too

  When I first swapped my old Motorola MB8600 for the NETGEAR CM3000, it wasn’t about getting a faster port - I was chasing an intermittent connectivity problem and wanted a second, newer modem to help rule out whether the modem itself was at fault. The connectivity problem didn’t go away with the swap, which turned out to be useful: it meant the issue was upstream on the provider’s side, not either modem. I ended up keeping the CM3000 anyway, for an unrelated reason - its 2.5 GbE port let me actually use my ISP’s higher-speed tier instead of being capped at the old modem’s 1 GbE ceiling. The…

• Works well just on the pricey side

  A power surge from a storm fried my modem and this was the only available modem in stock at my local Best Buy. It was rather expensive there in comparison to other sites, but being an emergency it is what it is. There were some initial issues getting the system back up, working with a Deco Mesh system, but that was more of a Comcast issue with multiple screw ups. It is now working well and speeds seem quite good.

• Why aren’t all modems like this?

  I appreciate that it has so many lights to indicate the various factors of an internet connection. So tired of the single-light units out there that have you wondering what’s going on in there!

• Netgear

  I’ve been really impressed with the NETGEAR Nighthawk CAX80. Having a cable modem and WiFi 6 router combined into one device makes setup much easier and saves space. The WiFi connection has been fast and reliable throughout my home, with great coverage for streaming, browsing, and connecting multiple devices. I also love that I don’t have to deal with separate modem and router equipment. Overall, it’s been a great upgrade and a convenient all-in-one solution. Definitely recommend

• Nighthawk works with comcast after using install

  After moving, Comcast obsoleted my old router CX1000. Decided to go with CX3000 over CX2500 to be more future proof. Cable modem saves money every month, and the payback is about 1 year. If you plan on having cable for the long term, it is a great way to save money. You have to bring you own wireless router. Luckily, mine worked, but this could be a problem for new users.
