Awesome modem and a couple of excellent WiFi routers!

We use Spectrum cable and we were tired of unreliable service. I had plans in October to replace the equipment and upgrade the service plan. A family member asked, what would you like for Christmas? My response was A Nighthawk modem with Voice! Fastforward, I bought a MR70/MS70 WiFi router in October. December I bought a RAX42 WiFi router for Christmas also. Spectrum only allows their modem to connect to voice service ?? I was disheartened. I connected all of them up anyway and glad I did! The Nighthawk System works flawlessly. Day in, day out, even though Spectrum doesn't officially support my Nighthawk CM1150V Modem. The system is running 25% faster than Spectrum's internet service speeds! NETGEAR NIGHTHAWK SYSTEMS are the best for my internet needs!

Poorly Engineered Device

Like others notice the modem will barely be able to last a year. For me the initial issue was shoddy, cheap design which uses a plastic 'screw' to apply a downward pressure onto the modem's CPU. In my case it had become dislodged. This had lead to issues where it would sporadically work. You could hear a rattling in the case. I had to take apart the modem & noticed the screw bit was broken. I also noticed they were using some crap thermal pad. I went and bought a new thermal pad & reapplied the heat sink using a screw to replace the broken bit. It has fixed the modem however the shoddy construction has caused issues for the modem & still suffers from the existing, built-in, ware & tare that makes the connection finiky where I'll have to start the modem with zero ethernet connection otherwise it fails to get past boot diagnostics. I wish I had noticed the CPU heatsink issue sooner as to avoid the damage of this shoddy design. A nearly $300 dollar modem should be better engineered, not just engineered for quick fabrication & short lifespan. When it operates the speeds are nice as it does meet the standard.

Great Modem!!! works flawlessly with Xfinity

This a great modem ive had it for 2 years now and have had zero problems and have saved a ton of money because of it! after reading all the bad reviews I was dying laughing most of them I could tell had no idea how this equipment works one guy says it doesnt work with Comcast LOL It does! you probably set it up wrong ..People Comcast doesn't want you to buy these things because it costs them money so what they do when you have issues is they tell you its broken when its not .. when I set this up I didn't even have to talk to anyone from Comcast ...before you buy this read up on it watch a video etc and you won't have any problems .. another thing because you have 1000 Gb speed internet that doesnt mean your going to get that speed to your devices .. the more devices you have the lower your speed is going to be going to them.. I will say this this modem is great my speed was improved and I dont have to pay rental fees etc anymore .. also thank you for the entertainment with the reviews claiming it doesnt work etc I love coming to sites like this and Best Buy to laugh at peoples reviews when its user error 99.9% of the time .. educate yourself before you make a big ticket electronic purchase

Does not work

Comcast remoted into modem and determined it was receiving the signal; but, the two computers and Wifi could not see the internet. Switched back to the Comcast modem and all worked well.

Pleasantly surprised

I decided to replace my rented modem with this one. I already have a NETGEAR router and after my research I felt this one would be the best for my use. My order came promptly and the set up of the new modem was trouble free. I feel like the new modem is providing me with faster service. So far I am very pleased.

DOES NOT WORK WITH XFINITY

I bought this today thinking it would work for my 1gb Xfinity service, but regardless of what the box says, the company refuses to service this router. Don't use this as a selling point if it is literally just a lie. I really don't get how you're able to print that on the box if the tech assistant says they will not service the router

Incredible upgrade!

By Jacob C.

Finally decided to upgrade my Xfinity provided and woefully unreliable Modem/Router combo to this Modem and Netgear R7000 Router (which I also highly recommend and the difference is incredible! Before I was only getting 90 Mbps and frequent dropouts and now I've been getting a consistent 200 Mbps (keep in mind I'm only on a 175 Mbps plan) and so far absolutely no drop outs or slow downs! I was expecting a minor improvement but I was not expecting this much of a improvement! Set-up was straigh...
