SURFboard SBG10 DOCSIS 3.0 16 x 4 Gigabit Cable Modem & AC1600 Wi-Fi Router | Comcast Xfinity, Cox, Spectrum | Two 1 Gbps Ports | 400 Mbps Max Internet Speeds | SURFboard App | 2 Year Warranty

This is a good modem and wifi to buy all in one.

Works well. Easy to set up. I had issues but that is on my internet provider's fault. This modem has been working well for 4 days now. Will update in the future if anything happens. Update: It's been like 5 months now. I've been using internet via this thing without any issues. One thing I gotta say is my internet service is 50mbps, way below the capability of this modem router, so I cannot comment in term of max speed. I do get all my 50mbps. I have Xfinity. This device has been very reliable with my current service. I never had to restart the router due to drop connection in the past 5 months. (I had this issue a lot in the past, not sure if due to other modems/router or due to my previous internet services.) This device got 5Ghz wifi which allows me to play Xbox games from the cloud. In short, great device, I'm glad I bought this. I actually bought a used one here for maybe a third or a quarter the cost of a new unit

Didn't cover good range

Ok

It's been almost 9 days since I replace my clunky, big, hot Spectrum Internet modem with this Arris modem. My Internet connection has not dropped once since I connected it up. With the Spectrum modem it was dropping almost every day (which if you work from home is a real pain). Setup was super easy. Moved the 2 cables from my Spectrum modem to the Arris, called the cable company and asked them to activate the modem. Took less than 10 minutes for the whole thing. NOTE: 1. Change the password on the modem as soon as you set it up. Very important! 2. If you have another device at home that provides wireless connectivity, like I do, disable the wireless connectivity on the modem - you don't need it - and it protects you from drive by wireless hackers (they are out there). You will see the 2 wireless lights on the front of the modem go out. So far, very happy with this purchase. I will return my Spectrum modem, and most likely my Spectrum cable box too. Spectrum is constantly raising prices - it never ends - and I rarely watch cable TV anymore - it's all crap. I have transitioned to steaming TV, and no longer need the cable company for TV.
