great price great product
Customer Customer –
Great company, the modem came on time with fast delivery and it worked. I am a very happy customer.
ddsngoi Customer –
A+++
JR NY Customer –
Works as advertised on Optimum and registration was really easy. I removed one star since it didn’t arrive before my cable installation appointment, despite the word of the vendor that it would (in a direct message). I had to rent one from the cable company for a month.
bob-b Customer –
works great no problems
Bob W Customer –
A perfect replacement for that Optimum modem that you are renting every month.
bradjag Customer –
Worth the price to save me money from Optimum. Pays for itself in as little as 8 months.
Customer Customer –
It works perfect with my optimum internet. Highly recommend.
Brook607 Customer –
I bought this to eliminate the modem fee from Optimum. So yes, this is compatible with Optimum. I have Optimum voice, so I needed a modem that has a telephone port, which is called a telephony modem. That’s what this is. Hardly any retailers sell them, so you either buy it here, or buy it from Arris directly.I purchased it new from DOCSIS Networks. They’re ok, but their customer service isn’t the greatest. They’re not so helpful when it comes to tech support. Keep in mind that the “A” version of the TM822 is not supported or warrantied by Arris. Optimum rents the “G” version.The modem did not come in an Arris box, nor did it have an Arris warranty. It didn’t come with a user manual or quick start guide either. Makes me question if this was really new.I’ve been using it for a little over a month, and so far so good. I’ll update if I have any problems with it.
Nevermindme Customer –
Product arrived quick, in good condition and well cleaned from wherever it’s previous deployment was. Powered on nicely and has been running like new for roughly two months. As a nice bonus, it’s smaller than my original TM822 from Optimum. It got a little too warm for comfort when placed in a somewhat confined space but that was easily remedied by letting it breathe a bit. A great buy that saves on the internet bill 🙂
Customer Customer –
This product worked perfectly with the optimum service I already had in place.super impressed with how easy it was to hook up!
Thomas Lindsay Customer –
This modem was not needed. Cable vision switched to Altice. Had to return it unused. I gave it four stars for fast delivery and refund on return.
L.I. Mom Customer –
No problem hooking up to Optimum on Long Island. 15 minutes on the phone with cable customer service and the CMAC # and I was all set. Make sure you call cable company from your cell phone.
RB NYC Customer –
Saving me $5 monthly for cable company rental fees. So far works perfectly.
Jeff Hart Customer –
A++
Bernard Randall Customer –
Fully Comcast comparable… Running like a champ with speeds of 270/14.
Customer Customer –
works perfectly easy instalation
Rendasha Customer –
perfect! Works just like it should
Chip T. Customer –
Perfect replacement for Cablevision / Optimum customers with broadband speeds below 300 Mbps (which is most people)
Dawn Customer –
This modem integrated perfectly with my new Optimum high speed internet service. It was one that they recommended on their website. Speed tests for my 100 kbps service are showing higher than 100. Very happy.
almamy wague Customer –
Great price reliable!!!!
Nsheeheed Customer –
Works perfectly.
acoustic85 Customer –
This modem worked perfectly with Optimum Online 100mb/s internet in NJ. The modem’s number just needs to be registered to your account by the technician or you can probably do it online.
steve Customer –
works great
warren Heller Customer –
Up and running fine.
Dennis Poletto Customer –
Great item and price
Customer Customer –
I’ve been using this modem for a month now and it’s working flawlessly with no discernable difference with the Optimum modem it replaced. The only feature lacking is a battery backup for the voice over internet phone.
James manning Customer –
so far so good.. works with optimum cable (long island) just have to call cable and give them a few numbers off the new modem for them to register and send old one back by mail or drop off ..saves about $70 yrly off over inflated monopoly cable bill
Customer Customer –
Just what we needed to hook up Optimum in our new home without the monthly rental fee from the cable company! Be sure to check the list for YOUR provider.
Jeff D. Customer –
Works great and save me monthly charges
Gman Customer –
Have it for about a week now, can’t complain.. for the price I got ($35) it is a no brainer !!! Would easily get my ROI in 7 months where cable company charged 5$ a month for rent..:).. I hope it works the same way for a looooong time :)..
Vikram Mittal Customer –
worked perfect for replacing my dad’s Optimum cable modem. saves $10/month by buying this modem. Pay back in 3 1/2 months
seref baydemir Customer –
Excellent
joe natale Customer –
Replaced the cable co provided modem which i returned for a $10/Monthly discount. Not bad Invest $30. once and save $10 every month that I have cable it pays for itself over and over,
zap Customer –
works well with optimum. Five star!
Tazman Customer –
works like a charm, I hooked it up to my Cableivision Coax and with their easy setup it was a breeze.
Brian Customer –
Works with cablevision
Tommy Customer –
Working as it should be… good deal without having to pay the carrier a rental fee every month.
Profoto Customer –
Works fine with Optimum in NJ. Set up was easy and a call with Optimum service rep was all that was needed to be up and running.
John Customer –
Replaced my Optimum/Cablevision Modem with this and it works fine. First I called Optimum to register it but as my phone is through cable, I lost the guy helping me once I unplugged the old one (duh! -but he told me to unplug it!) You can also register it online, which it what I did, rather than call him back. My phone works with it as well since it has “telephony.” No rental fees for me but it will take a while for it to pay for itself, as it was over about a hundred dollars and I think the rental was five dollars per month.
Stefan Makuch Customer –
Worked great. Took less than 5 minutes to install.
Customer Customer –
Works very well
Hasan Customer –
Never realized that I have an option to own it and save some money instead of paying monthly rent to Optimum forever!
Ricardo D. Customer –
Helping me save money on my optimum bill. Works just fine.
Guillermo Casiano Customer –
GOOD
David Customer –
I purchased two of these, one for me and one for my mom because I’m tired of my cable company nickel and diming me. I’m saving a combined 10 dollars a month by purchasing these modems which will pay for themselves in 8 months. Very happy with these purchases. 👍🏼
valery Fosse Customer –
Work very good with optimum
Kim Hyun Suk Customer –
Works Fine with OPTIMUM internet
virgilio Tovar Customer –
Excellent. Worked without a hitch. It was all very easy to set up and cable co (Optimum) activate it over the phone.
Cheapskate Customer –
Has been reliable and has not had any major issues. Sometimes things slow down on my network but that mainly seems to be due to my ISP and not the modem itself. I am using this with buckeye broadband. Not sure what else it works for.
