Customer Ratings & Reviews

This modem was exactly what I was looking for and I love the look of it as well as how the lights on the front aren’t super bright either. Runs pretty cool and gets me more than enough speed. I have a 600 MB plan and when doing an Xfinity speed test connected directly to my Linksys router, I actually get over 600 MB with the test. On my phone, I get up to 450 MB with an iPhone 11 Pro, Downloading anything is even faster now and much smoother no matter the file size. Setting up the modem was also relatively easy. At least for me, I was able to set it up through the Xfinity app without having to talk to anybody at all. There are 2 gigabit outputs on the back and the second one you do have to contact xfinity to get it activated. But at the moment, I have enough hook ups with my router so I didn’t bother with that yet. Also I don’t have an actual phone to hook up to it yet, but the phone icon is lit up on it and I have a phone number which it shows through the app, so I’m assuming I’m all ready to go if I want to hook a phone up to it. So it’s nice to know I have that option now if I ever need it. I don’t currently work from home, so I don’t need it at the moment. Definitely recommend though and worth the money. It’s also 3.1 DOCSIS so at least you’ll be set for awhile with this one even if you don’t need it right now. It will get you all the speed you need and comes with 2 VOIP phone jacks and 2 Gigabit ports which is nice.

Ever since it was installed, there was a big difference in speed over my old router. It has been very solid performer with my Comcast Extreme Pro speed (600 Mbps).

Difficult to establish Xfinity voice service, does not automatically set up with Xfinity as advertised, but once Comcast finally got it remotely configured with their system, rock solid, reliable, with excellent VOIP voice quality. I highly recommend, but you will have a 30+ minute service outage until Comcast gets it remotely set up. You also have two separate MAC addresses for the device - I apparently gave Comcast the wrong one which delayed my service.

I was able to get the speed i am paying for with comcast with this modem

Comcast upgraded my Blast! speeds from 200 Mbit to 300 Mbit so I needed a new eMTA. I wanted DOCSIS 3.1, so this was my best option. I am now getting the speeds that are advertised. I had to call Comcast to get it activated, but that didn't take much time. All I had to do was give them the MAC address from the bottom of the modem.

Easy to set up for a less than technical person. Ratings are good.

Good router overall but the specs are kinda deceiving. The router advertised 2gbps max download speed. To do this though, you have to enable what's called, link aggregation and have a router that supports both link aggregation and has a 2.5gbps ethernet port. You also then have to call Xfinity and have them enable the second ethernet port. Basically, since the modem only has 2 1gbps ethernet ports link aggregation syncs both ports so they work together to give your router 2gbps. Certainly not straightforward forward and the average user will have no idea how to do any of it. Had to find a specific version of the manual to even find out how to enable it in the modem settings. When I went to the settings there was no option to enable link aggregation for me or tweak the front panel lights like the manual showed. I got the modem to future-proof me for speed upgrades but I'm having doubts about getting link aggregation to work when the time comes. Overall though it's working fine and does the job.

Very satisfactory! Relatively easy to install and set up, works very well.

I totally agree, paying over $200 ($224) up front is alot but 10Gb future plans from it is a great deal. Almost went with Netgear CM1150V myself to try something different from Arris but again, at 2Gb. Not worth it while we get added stuff around Tech reaching nearing 48Gb 8K-10K hdmi cables. If there is really a notice difference from those besides if there's any market propaganda in there. The problem at the current moment at this time, No Router I've seen has contain 2GB Nic's built in except maybe a few Netgears Gaming router only having 1 at 10Gb Nics while the rest having 1Gb Nics (total of 6 nics maybe). 1Gb Nics been around since routers like Apple Extreme 5 Gen (current Apple Extreme 6 Gen Discontinued) - 6Gen Still contains 1Gb Nics. Which leads me to the other problem that I have notice on this products Aris T25 description. Says 10Gb's but with 2 -1Gb Nics. Now lets think about this clearly, How can it run at 10Gbps on this modem with 1Gb Nics? How can you distribute amazing 10Gbps on the coxial cable onto 1Gb Nics? And they say they support up to 2Gbps since ISP's are still rolling out 1-2GB plans to people around the country. Has anyone tested the Nic themselves from one pc to the other with a NIC card contain 10Gb to see if they really truly in fact have 10Gb speeds?? That's the real question there. Has anyone tried hooking 2 pc's together using this T25 Modem 2 Nics only without hooking to comcast yet with 10GB Nic cards added to there PCI slots to actually test that theory yet? What would the results be? And would it be the same after being hooked to comcast after unpluging the coxial cable? And the other problem with this modem is, what's the password under advance? Whats so secret that needs a Password Protected? Met to look further before I had set it up with Comcast and now its to late, Perhaps someone could let me know and post a screen shot for me and others to see bc there pdf file from arris doesn't mention about this section of this modem at all. If its for ISP, then what pre-tail is it? Private concerns. Phones aspects? Some say I'm just being paranoid and not worry about it or some kind of conspiracy or bad Advertising? But this is my honest Review for this product, Its how you take the information in. The Good, The Bad and the Ugly. (Ba-Dum-Ts) or is it? idk. idc. I hooked it up and was ready 5-10mins for checking speed plan. May take 20-30mins to really see the speed difference as it catches up. The Display page is very basic compared with other Arris modems of the past. Overall, 4 Stars. Probably really should give it 3 Stars. After typing all this down. or will this be review removed? Q. when will there be a Linux Rapsberry Pi type device with a coaxial for being the modem? haha, keep dreaming, LOL

This Arris T25 modem works perfectly for our Xfinity with Voice service. You will also need a separate router to have WiFi throughout your home. It still beats out renting a gateway from your provider in the long run! This was set up and activated by the Xfinity technician with our new service, so I cannot attest to the ease or difficulty of installation. However, I watched him and it seemed pretty straightforward.

The Geek squad at Best Buy were able to direct me to the exact product to buy, and it worked out well. I was able to restore all three tv's as well as have my home phone fully functional. I appreciate the ease it took to hook it up, as I am not electronically knowledgeable. I fully recommend it.

Great throughput!! Phone connection fit perfectly and setup was a breeze when calling in to Xfinity to activate.

I have had this up and running for only a short time but see the difference in my interest speed. I would definitely recommend it.

Trying to find a Docsis 3.1 modem with voice is a chore at best. But this one is it. Finally upgrading from my previous 3.0 modem allows me to get the speeds I’m paying for. The channel bonding is also very apparent by an increase of speed and packet transfer. I paired my modem with my Nighthawk seamlessly and I couldn’t be happier with my internet service.

easy to set up and make operational. WIFI in house is spotty without internet. recommend you download carrier app before cutting over

Super easy to set up, delivers the promised speed. The only caveat is that Comcast disables the second Ethernet output so you still need a switch or a router if you want to hardwire more than once.

Excellent modem for the money. The next best modem that offers a telephone connection is nearly double the price.

Quick and simple setup for Xfinity services. No issues that come along with typical Internet setup using your own equipment. Make sure you use the correct kind of coaxial cable or get from Xfinity. Modem has performed fine and no problems so far!

Good price, excellent product and customer service!

Just to save you the time that I wasted over the weekend. If you install this modem AND you have Xfinitiy's 1Gb Xfi Advantage -- that's the high-speed plan that includes unlimited data -- Comcast will remove the unlimited data feature from your account (plan details here: https://www.xfinity.com/support/articles/xfi-advantage-faqs). So, yes, you'll still have 1Gb speed, but you will be paying for data in excess of 1Tb each month. If that works for you, then go for it. My family exceeds that each month, so any savings I might have gotten by having my own modem would have been canceled out (and then some). Unfortunately, I didn't learn this until I went through the installation process, called Comcast support twice, waited on hold and finally spoke with a helpful rep who told me the bad news.
