ARRIS - SURFboard AC1900 Dual-Band Router with DOCSIS 3.0 Cable Modem - White

I installed the Arris Surfboard 1900-AC at my father-in-law’s house to replace an older MODEM. The installion was easy and did not require any phone support from Xfinity. I did a speed test before and after the installation and found I improved the download speed at his house by nearly a factor of 2. I also took the opportunity to install a UPS to support this MODEM and an Arlo base unit. I have found that installing a UPS with a cable MODEM significantly improves the reliability of the MODEM. I hardly ever have to reboot them when they are on a UPS. I have found that without a UPS, power fluctuations can cause far more problems that require a reboot to fix.

It was easy to set up the device. It's works on all my devices.The wireless is very fast and the Ethernet work great on the cox high-speed network.It easy to hook up my wireless print and set up my network....Over all i say am so happy with decide to choice this modern! I been having it for a day now no problems to speak about hoping it stay that way. An it work good with my cell phone and google cast with no no problem with link them to my network et.... the cost was over 200 but got the price matched that best buy offer. either way i think it work the easy cost because i don't think i need another anytime soon. . always be on the look out for prices and research on a idea! one last thing the replace plan is worth getting just in case something happens!

I was used to the sort of setup it would take to get the product running at optimal levels, which is a beast of a machine when you get it running right, that runs as a modem, and a router at the same time as I have between 4 and 7 devices running off of my wifi at various times with this machine, and even though I'm paying for 100mbps wifi, my main desktop computer is clocked at 180 mbps on speedtest.net. It handles everything I've thrown at it so far.

This cable router works great. It's been 2 weeks since I bought it and hasn't had any hiccups. I have spectrum as my provider and this router was easy to set up. I was renting a router from spectrum for $5 a month, but decided to buy my own since I'll pay more renting then buying one.

At first I bought a less expensive one but I went back to the store to exchange it with the best one. The unit has download speed of up to 686 Mbps, 4 Ethernet ports and 2 UBS ports. That way, I don't need to upgrade it down the road in which it will cost more time and money. Very happy with the product.

Works beautifully with my xfinity cable system. I connect to all of my devices without any problems.

Seems to lose the signal occasionally , But I haven't determined if it is the router or the provider. it's appearance is 10 times better than rented one from provider. looks great in out office.

I purchased the Surfboard SBG6900-AC to replace a cable modem and separate router. The Quick Start Wizard does an excellent job. I did try to tweak my setting and that was not a good idea. I started over and with only a very few changes have had excellent and reliable coverage. With my old router, I had to use an extender in our family room. I have COMCAST's Blast Internet. As can be seen from the SpeedTest I just ran, I am getting an outstanding download rate. I have seen only one outage lasting 35 seconds since my final setup. This could well have been do to other factors and not the Surfboard.
