Solid modem for Xfinity wifi. Have gig speeds. works well.

I purchased this modem to not only future proof myself for years to come but I didn't want to pay the monthly rental fees Comcast/Xfinity was asking to use their modem. Setup was a breeze and I was up and running at great speeds in no time. It's a little expensive but worth it - go get yourself one of these if you're looking for a good cable modem!

Holy smokes night and day difference. I purchased this item to upgrade my modem since my old one was running super slow or would randomly cut out. Took awhile to get connected with my internet provider but once hooked up my internet speed skyrocketed. Greatly pleased with this item.

Easier to install than I expected. I needed an updated modem that was compatible with the faster Comcast speed, and this was just the thing.

Seamless replacement into my Optimum cable drop. Works better than original. Been up for 3+ months. No issues at all.

There’s really not much to say. It works great. Easy to setup!

Outstanding product very fast and smooth great for gaming

Absolute pain in the neck to set up since ARIS insists you open an account on their website even though you bought from Best Buy -- then you have to call your ISP (Cox uses this modem but hassles you endlessly if you don't buy from them). But it's working now and still working.

Worked as the upgrade I expected to get the speeds my new plan advertised. It did take a few power cycles for it to settle after my ISP provisioned it and pushed a firmware update, but worked fine afterwards.

Just what I needed as I already had a mesh system. The salesperson confirmed I didn't need a modem and router as the mesh would take care of the wireless network.

Have had this installed for ~1 month & it works excellently. No hiccups, etc. Haven’t had to reboot it at all (even after a couple of short power outages in the apartment complex). I replaced a modem/router combo I was renting from cable company, and very happy that I did!

We were having a hard time getting work done, communicating with friends and enjoying entertainment. Then, your https://www.bestbuy.com/site/arris-surfboard-32-x-8-docsis-3-1-cable-modem-white/5839003.p?skuId=5839003 came along. Everything's working like it SHOULD now.

Holy Smoke, what an upgrade. I had the SB6183 and that was one of the best modems I’ve ever had. I have not had a single hiccup with this change. Trick is when they ask what the modem is tell them another 6183. Don’t elaborate and change the subject.

I recently updated my Comcast subscription and they informed me I would be getting up to 300Mbps. I reset my current network interface, but Speedtest.net would only report a speed of a maximum of 152 Mbps. After speaking with a tech, I purchased this interface. After installing it (and registering it with Comcast), Speedtest.net reported 310 Mbps.

It was the best exchange I made with other arrius that didn’t have the router. This one have the WiFi and Router portable . It quick, efficient , lightning fast and installment is easy. I love it! Recommend hundred percent to anybody . That want to save money on equipment fee when getting internet service from Comcast or cable services

Using this modem with Cox internet service. Works as it should have not had any issues since purchasing.

Probably the best modem I've ever bought. It's well worth the price and I've had great results from the moment I installed it. Highly recommend!

Very easy to install. Very fast as well. It works well!

Modem works ok. Does tend to get warm to fast.....

This cable modem was easy to hook up, and has provided steady connectivity ever since. I paired this with a router to connect the rest of my house over wifi so I'm not paying monthly rental fees to stay connected.
