    Fast with excellent wifi range

    Connected to Mesh System

    Router combo is working well. However, it took several days to get it started. I had to have an cable company tech connect a cable to my mesh system. The combo router had separate connections for the internet (cable) and the wifi systems. I did not know this and after calling the surfboard techs several times, I was finally connected properly. I do not like the fact that the modem router is not completely wireless since I needed a cable for the mesh system. Other than that it is great. My speed is faster than my old combo router.

    Excellent choice in a combination router/modem!

    Great combination modem and router. Saves space from the old setup. Needed this to take advantage of the current internet speed. Easy setup and works great!

    Buy a warranty with it! Worked great for 14 mon.

    Item worked great for one year and 2 months. Suddenly at 14 months old it no longer recognized itself as a router. Thankfully I had a cell booster that still allowed me to have internet. I called my internet provider and verified this. Then I called ARRIS customer support. They ran tests and verified it was dead. They asked me if I had purchased a warranty with it, which I had with the recommendation from a Best Buy technician when I purchased it. I'm so thankful I listened and paid the additional $49.99 four year warranty. I returned it yesterday and got another set up, and another warranty. Over all, yes this works great. No issues whatsoever setting up and using it for 14 months. But I have to admit, I cannot recommend a product that lasts hardly a year later, regardless if electronics age out. It was kept dust free, out in the open and never allowed to over heat, not near a window, etc. So get it, but buy a warranty with it. Thank you Best Buy for standing by the products you sell and for having outstanding staff working there.

  • Will this work with quantum fiber

    The SURFboard G20 is a DOCSIS 3.1 cable modem combined with a Wi-Fi 6 router, specifically designed for use with cable internet providers such as Comcast Xfinity, Cox, and Spectrum. For fiber-to-the-home or Ethernet-delivered service, the G20 can be reconfigured to function solely as a Wi-Fi router by disabling its integrated cable modem. Since the G20’s Ethernet port only supports up to 1 Gbps, your Fiber Internet speed will be limited to that maximum.
