Works nicely….
This was a terrific purchase. I initially got one (another Arris) from Best Buy that didn’t have phone jack ports for a landline. I was subsequently informed that that comes on a more expensive unit since apparently landline modems are a thing of the past. In any case I needed one and found this one, love the price, installed the unit and Comcast was able to provision it so that it worked without any difficulty. Big win for me without spending the crazy sums of money required for a comparable model at a store like Best Buy!

Malfunctioning, no internet, no support, too late to return
I had high hopes to a battery backup 911 phone line, modem and router “all-in-one”, but this specific unit was a trasher and the manufacturer’s support was very bad.While it’s my fault that I didn’t try to install this before the deadline to return it, it reflects on Amazon’s refurbishment program that the device had serious problems when I got around to it (four months later). Could not connect to internet (after extensive diagnostics, including service provider’s technician spending an hour on it.) In addition, I couldn’t log in to the web-based settings framework. Ethernet didn’t register at all until after the first (of three) hardware resets. This couldn’t have all happened since Amazon shipped it, this strongly indicates that Amazon sent a broken product without properly testing it.The device itself has certain issues with the manufacturer – their web page for this product does not provide a link to the manual or firmware update(s). Arris has no excuse either.Lots of wasted hours by multiple people and interruption of an essential service – absolutely not acceptable.

Worth the price and a perfect size
I wanted to upgrade my WIFI router and was looking for something that would work with my service but this router works great and I can connect the ethernet when needed. The WIFI speeds have been great so far and no real issues have occurred. If you want to upgraded from your Internet provided I would recommend this WIFI Router which is a 2 in 1.

Call Arris first for correct cable modem for your needs -Finally a WIFI cable modem that works
I have Xfinity as my provider who first recommended I blow 200 bucks on an Arris G36. Lost 160 bucks on that as by the time I installed it, too late to return. Then they recommended an Arris T25. Still have that dust collector as same deal, can’t return and no one will give me 20 bucks for it. Finally called Arris who knew their stuff and they recommended this WIFI model that I purchased for 65 bucks refurbished and works great. Arris customer service dudes seem to be from India but work in downtown Philadelphia. Don’t care as the folks at Xfinity are nice, don’t give me a hard time when I want to purchase a piece of equipment of my own but I lost around 400 bucks until I finally called Arris and knew exactly the model I needed. Long term, I’d save 15 bucks a month. It appears Iâm not the only person out there whose provider doesn’t have a clue. Moral of the story is to call Arris, tell them your provider and what devices you need and they will save you hundreds of bucks unless you try to install it right away and can return it. Anyone out there want an Arris T25 in mint condition? JK as I’ll post it again on Facebook’s Marketplace for 15 bucks and see what happens.

Good product, should have come with a manual though
I am fairly tech savvy so the lack of a manual was not too much of a hindrance, but I still wound up having to call their tech support line to get it set up. The tech was very friendly and helpful, and within 20 minutes we had my Internet connection up and running (including hold time), so no real complaints there. The device performs as advertised, and puts out great wifi signals at both 2.4 and 5.0 ghz. We run two smart TVs, a Ring doorbell, an Alexa, two laptops, 2-3 cellphones at any given moment, and someone is streaming most evenings and I have yet to notice any issues with signal quality. It is as good as my Comcast/Xfinity cable modem and saves me $14/month that I do not have to pay the cable company to rent theirs. I would buy again and recommend to others (just please make sure you include the manual next time!).

Easy Setup. No problems with Puma chipset.
2/1/21 Update: I’m on my second refurb unit and the problem is the modem keeps disconnecting. MDD timeout happens every minute, probably because SINR and dbmV are too low. I’m certain the two refurb units are defective because my old modem works just fine with signals well within parameters and connection stable. Thank goodness for Amazon Prime return policy. Stick with buying a new one and not a refurb!So far so good for this refurb unit. Connectivity is a big improvement over my older surfboard SBG-6782. This newer 7400ac has more channels, appears more stable and responsive, and was easy to set up with Comcast/x-finity. I canât comment on the Wi-Fi performance because I use a separate Ruckus R610 WAP which outperforms any combo router/modem/ap in my opinion.Programming was simple and standard for any Arris router/modem. Program your LAN IP address, set port firewall/port forwarding for your surveillance NVR, initiate modem online with Comcast, and I was all set and running after about 20mins.The only issue i had was slow speeds initially. Thatâs because the modem failed to update its firmware on the first attempt. Comcast updated the firmware remotely and my speeds are now consistently over 100Mbps.Very happy with this budget refurb unit, but itâs only been running for a week. Hope reliability is good and will update this review.
