The ARRIS SURFboard T25 performs very well and was simple to setup if you install Xfinity's app on your phone and select the new equipment option. The modem seems expensive because the internet and voice service.

This looked like a great modem, and I saw many positive reviews. I was replacing my Netgear CM500V because Xfinity upgraded my speeds all the way to 800Mbps for no extra charge. I was wrong about the whole thing.I got it, activated it, set it up with my Deco M3 system and it worked fine for a while. The M3 never properly accepted the modem change, showing an offline status. But, since I was still able to use the internet with Ethernet (and mostly Wifi), I thought nothing of it.Later that day, phone calls would frequently have drop-outs mid conversation and other quality issues would spark randomly. Additionally, I finally noticed that Wifi was being troublesome and the modem page (192.168.100.1) would frequently time-out and not let me view it. It would take 10 minutes to load a single page, not great when diagnosing something.I tried reactivating the modem with Xfinity, many reboots and factory resets later, I finally gave up.Turns out after googling, these modems still have the dreaded Puma chipset from Intel! Of course Arris hides this and doesn't show that anymore, but they still put them in regardless. There was never any hardware update to fix these issues with this flawed processer.I returned it after four days of endless troubleshooting and am not gonna bother replacing my modem for a while. My CM500V is still giving me solid speeds and reliability; I just wanted the extra tiny speed bump I was paying for. Little did I know that it would cause such pain.

I installed the Arris T25 modem about a week ago. It replaced an Arris Surfboard 6190. I bought the T25 to use Xfinity Voice which is part of my plan but which I never used. The modem has been operating since installation without any incidents. Internet download speeds went from 600Mbps to 900Mbps. The telephone line has performed perfectly.Installation was not as straightforward as I would have liked. Since I don't have an exceptionally strong cellular signal where I live I first tried connecting a laptop directly to the modem and using the Xfinity activate webpage from a browser. I got nowhere trying that. I always ended up back on a webpage that told me to download and use the Xfinity app on my smartphone. Despite the weak cell signal I decided to try the Xfinity app from my phone. Scroll down in the app to where it says, "Got new equipment to set up? Activate now." It worked fine. The app only asks for the modem's HFC MAC ID, not the MTA MAC ID. After a few minutes of watching the lights on the modem cycling the app reported that the modem was online and provided the telephone number assigned to it. That was it - internet working, telephone working, no call to Comcast required. I connected my Asus router to the modem and I was good to go.Update: A frequently asked question is whether the modem can be connected to extension phones in the home. The answer is yes. However, my first try wasn't successful. I connected the modem to a wall jack that's connected to all of the extension phones after first disconnecting the phones from my current landline supplier at their demarcation box. The phone light on the modem started blinking as if the line was in use, but it wasn't. The displays on my extension phones also showed "Line in Use." I disconnected the modem from the phone jack to think about what the issue could be. A few days later I tried again but this time thought to disconnect a printer/fax from its phone wall jack. All of the extension phones now worked perfectly. I'm not sure why the printer/fax would cause a conflict when it was not in use, but all of the extension phones are working fine now. I can live without the fax if I have to.Update March 14, 2024: I think it's helpful to update reviews after a product has been in use for some time. I've been using this modem for internet and phone since November of 2022, and its performance has remained absolutely solid. I have not had to reboot it once. Very happy.

I've had this modem for a couple of months now and it has been performing great, consistently able to get the maximum bandwidth for my plan from Xfinity (350Mb/s). (I'm sure it will perform to deliver gigabit speeds if the internet plan allows that as well, but I just haven't personally seen that.) No outages*. It was very easy to install, just hooked up the coax cable from Xfinity to it, and the Ethernet cable from it to my router. I started on the Xfinity web app for finishing the provisioning and set-up but unfortunately Xfinity had some bad data on my account, the app showed a modem that was from years ago, not the one I was replacing with this, so it kept throwing errors when I tried to go through the steps to provision the new one. So I did have to call Xfinity on my phone and complete the provisioning that way. It was quite easy, just 5 minutes on the phone, gave the tech the cable modem id number and it was up and running shortly thereafter.(*) I am giving this 5 stars despite an initial couple of glitches with it. In the first 2 days that I had the modem, it twice turned off by itself and, strangely, would not turn on again until I disconnected all cables, and then reconnected them, and then turned on the power. (Until I disconnected the cables and reconnected them, simply trying to toggle the power caused the LED lights to flash a few times and then stop.) This was very annoying but it only happened those two times and has not happened at all in all the time since then that I've had the modem and it has performed with rock-solid stability. I'm not sure what those glitches were caused by, possibly some provisioning issue at Xfinity still settling down? Or else just a total coincidence and some other event (power spikes or static discharges somewhere happened at those times? Regardless, since it has been performing without any problems at all for an extended period now, I feel sure enough to give this a 5-star rating.
