Customer Ratings & Reviews

Initial review The reason for this purchase was that I was paying for 600 for xfinity and was barely getting it with my old modem. After installing this modem I instantly got 600+ on wired connection and 400 wireless. So far so good.

This works great. Quit paying to rent one If you are you are getting robbed

Purchased new modem to accommodate increased ISP internet speed. This modem was acceptable to Spectrum. Had owned an earlier ARRIS modem model and it worked fine. This one works great.

I've had a previous ARRIS model and just like before am pleased with the stability of the product. No problems. Never needed a warranty on the other one and in fact, only reason I'm not using the other one is I sold it after disconnecting service with Comcast. Porduct kept its value too.

this modem is really fast. it works well with wow internet straight out of the box. it get me me full 500mb speed easily and should last a while since it is able to pull in well over 1gb internet speed. when paired with my linksy router it keeps the internet speed and doesn't drop at all

This works as advertised and it was easy to setup.

This modem was purchased to replace an all in one modem/router. I was having issues with pages loading slowly and security breaches. So I decided to not buy another all in one and split up my modem & router, ans the results have been extraordinary! No more slow loading pages and I feel very secure now!! Love this product!

Blazing fast modem. Seamless, easy install w/Comcast

My internet is now much faster and way more reliable

This modem was very easy to install and works great.

I should have purchased the cable modem years ago versus renting one. The internet speed seems much faster with no lag time compared the rented modem.

Bought this to replace SB6141. Had connection problems where I had to reboot my modem daily. Internet was working only few hours after rebooting then timed out. Called Comcast multiple times but problems continued. With this upgraded modem connection problem is fixed and get better download speed.

Easy set up and works well with my Comcast cable provider.

Easy setup with fast service...love this modem....

bought modem after my old modem suddenly died/crashed. After reading all the reviews at first i was skeptical but immediately we saw a big difference in the home network. My son even told us that he likes the new connectivity. Definitely recommend product to any

Have not had any problems with this modem. Allows me to get speeds a bit higher than what I am supposed to be paying for from my ISP. Paired with a good router this can be a great modem.

I had no idea what I needed, I only knew I wanted better than what the cable company rents. After explaining what I wanted to the Best Buy tech he recommended this modem. I don't know the specs, all I know is we are now happy with our internet speed so it's doing its job. I haven't regretted the purchase.

I've had the modem for about a month and it's working fine.

No trouble so far. I got this modem to kind of future-proof myself for the foreseeable future. It has no trouble keeping up with my ISP's paltry 200Mb down / 10Mb up plan. Perhaps it would struggle if there was more competition to offer faster data speeds where I live, but as it is, this modem serves its purpose.

I decided to buy my own equipment instead of renting the cable company's garbage. Man I couldn't be happier. Super fast and stable modem. I'm getting 63megs down over a wireless connection on a basic cable internet package. Kudos to the Best Buy associate who helped me pick out my new equipment. He was very helpful.
