I got this today and here is my experience. The router arrived in just a couple days on Amazon Prime which was awesome. Oddly, there was no CM MAC address on the label, although it says it is there in the instructions found online... However, I was able to get into the routerlogin.net admin control through direct ethernet connection to get the CM MAC address... However, it still did not activate on XFINITY. So I had to call them. They registered it and then it could be activated, then I get them the CM MAC address and it worked great after that to the MAX of my internet provider speed. Yet the WiFi does seem weak in just the other room, not bad though.
If upload is not that good it could be the internet provider, that was the issue here.
It does seem to get a bit warm so I put a little USB fan on it. I have a feeling that's the trick to keep it lasting a long time. If hardware gets too hot for too long it can be damaged and then get faulty performance.
Wish everyone great performance to the people who buy it. I may get another WiFi switch if needed to expand it but it's great start for today to have my own router and to save on the monthly rental costs. Good luck to you too.

Este módem router es perfecto no necesitas de un router ya que bien dos en uno, yo no leí bien la información del producto o mejor dicho estaba en duda si no traía el router ya incorporado pero si es dos en uno, ya no necesitas comprar aparte el router. Y activa el WiFi

I can only share my own experience in a very small local area network infrastructure here in a small studio apartment. Connected devices included 1 Vizio smart TV, 2 Motorola e7 Power Android cell phones and 2 laptops, all on a mix of N and AC WiFi. The latest speed test showed data throughput of 154.6 mbps down/5.49 up on a 200 mbps cable internet service with Comcast. No slowdowns or delays noticed on any web browsing or video/music media playback. The standard Netgear genie firmware provides a good level of control over your router and internal home network. I don't believe this model is able to be modified to run customized firmware such as DD-WRT. Overall a convenient and versatile device. Not having to have a separate cable modem and router is helpful and savings-friendly

If you're setting up a new cable internet service, this thing is the move. It's a way better value than paying $14/mo to "rent" the XFinity router, and it works perfectly.

It has both 2.4 and 5GHz wifi signals, which is super useful. My new tech like my phone and laptop can use the 5GHz to get full download speeds anywhere in the house (my room is in the basement and the router is upstairs, and I still get a full signal) while my old tech like my PS4, which doesn't seem to like 5G, can use the 2.4 and still get plenty of bandwidth for streaming. Router settings are also super easy to manage"”thank you Netgear! Just make sure you type in the actual IP address to access the router and not "routerlogin.net"; that doesn't work.

Definitely get the refurbished one. A new one of these guys will run you up awfully high for no reason. The used one works perfectly!

My parents moved and they decided on Charter cable internet with no cable/TV. This was real easy to setup and then call to give Charter the MAC address. Took no time at all and it walked me thru everything once connected to the cable that was already in the house.

Plug in the Charter cable.
Connected my Chromebook with a CAT 5
set it up
Called the number from a link it took me too and setup an account. (this is the only part that could have been easier with an online setup process rather than a phone call but that has nothing to do with this router and everything to do with the provider of the service in our area) Still easy.
