ARRIS - SURFboard AC1600 Dual-Band Router with 16 x 4 DOCSIS 3.0 Cable Modem - Black

I called Comcast to double-check this modem and model will work with Comcast. "Yes". Only concern is it new? They can't take a previous customer off that internet acct to activate modem without that user calling in and going through closing process. Buy New Only! Within 10 minutes it was going. Took rented modem into Comcast the next morning. They said call in (or Chat) to have the modem activated with specifics on the account. Did that through chat. It took 5 minutes and now on Xfinity acct can see the exact modem and you can do things with it through Xfinity.com. IT'S FASTER THAN THE RENTED MODEM I had from Xfinity! Update: It uses less 'data usage'!!!!!

It has dual, separate bands, one 2.4 gigahertz & one 5 gigahertz. If your device is able to use the faster speed, it will recognize it & it will show up as an option to connect to. If your device is only able to use the slower speed, that's the only one that will be an option. You can choose which one you want to connect to if both are available. That's nice because the 2.4 gig works better over distances & through walls, although it's slower. It wasn't as easy to set up as some, but it wasn't difficult. It's also nice to just have one device to worry about instead of separate modem & router. It has a guest password that allows guests to use the wifi without them having the power to change any settings.

This is the second Surfboard I have had. The first one was plug and play. This one very much was not. Confusing. I had to replace the first one because it died, and I did not have internet access. Without internet access, it was virtually impossible to set up. Adding to the confusion was in the instructions it said that you had to download a phone app to install. When I called for tech help, I was informed that THIS version of the surfboard did NOT require that app. So after two phone calls, and a lot of frustration in set up, it is working well.

After years of paying extra each month to my internet provider to use their modem, I decided it was time to buy my own and cut out the extra cost. I found this one, which was smilier to the one I had been using, but was a little faster. Also, it happened to be on sale that week. I want to let others know that you have to contact your internet provider and give them some information found on the modem (and on the instructions as well) before this modem will allow you on the internet. Once I got that taken care of, the rest was easy to set up and my system works as well as before.

Bought this to save $14 on my monthly rental of a modem/router. Was easy to hook up (but read the instructions...we didn’t and would have saved time calling Comcast). Noticed no change in upload or download speeds from the Comcast box. Will pay for itself in rental speeds in no time. Almost bought a Motorola one that was a bit cheaper. It would’ve worked now but technology was so old would have likely become obselete in a few years so I am glad I double checked with the sales person.

So it is very easy to set up and is very consistent. I like the automatic channels setting and the range is great for my three bedroom home . I am able to get 400 mbps WiFi 5Ghz with this on a regular basis with spectrum . I rarely have to Reset it . This does have a limited amount of Ethernet ports but it is fine for my needs . Price is right and does everything you need . Video streaming and online gaming works fine and smooth . This is a great buy

Had to call ISP to turn on new router which took several minutes and more complicated than necessary. They asked for "Password" on new router. There is none. It is the "Security Key" which I could not see because it was already hooked up, hard to get to but I found a copy of the label in info that came with the router. Hoping router will last a long time. That is a chance I took to stop paying monthly rental to ISP. It will take about a year to pay for itself.

My computer was showing slow internet speed and my old modem died while in the process of trying to fix the problem. I bought this one and like having the router combined with the modem. It wasn't the solution to my slow speeds, but with some other "fixes" I'm back to high speed now. My internet provider wants about $10 per month to rent me a modem, so it will take only about a year for this to pay for itself.
