I have it on UPS and it has NOT been reset in 4+ months since I activated it! Delivers 90-100 Mbps and one land line. It has an additional land line jack, but I don't use it. Land line voice quality is very good, with no hum pickup or digital noise. I have it feeding into a a/c band wifi router and a gigabit wired switch that runs to all rooms in the house. The entire system runs without any baby sitting. Provider is Mediacom for those wondering about compatibility. (There was one service outage because a car rammed into the distribution box in the neighborhood, but the modem reconnected on its own -- I mention this because many know brand names need a manual reset). Review: Excellent Modem! - Excellent Product! This is the Exact same product/Modem that I was renting and being charged for with my Internet Services. It works the same and serves the same purpose as the one that I was being charged for with my Internet Services. The setup, speed, compatibility and connectivity is the same.

Thank You! ### ⭐ Trouble in a box. *by H***D on April 6, 2021* These units are refurbished whatever that means. To me, it means they don't work more than half the time. Absolutely garbage, & Optimum won't allow any new units to be sold if you want their phone service. So, either you rent one from them at $10/month which adds up fast, or you buy one for $70 or so, take your chances. I've gone through 4 now and they drop the signal every day. I have to turn it off, unscrew the very difficult & painful coax cable, & hit the reset button. EVERY DAY. I've returned 3 looks like it's going to be a 4th here & we're going to have to drop our phone service so we can buy a new modem. We're going to lose the functionality of our expensive all in one printer's Fax capability. This shouldn't be only choice but it is with Optimum. Unfortunately, Verizon is even worse. We dropped our cable & got Roku, which we actually love, but it requires, you guessed it, a streaming MODEM. This isn't a Sophie's choice, but it sucks & so do these modems. Don't buy them. Nothing but trouble. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/34242415-arris-tm822-series-tm822a-touchstone-docsis-3-0-8x4-ultra](https://www.desertcart.tn/products/34242415-arris-tm822-series-tm822a-touchstone-docsis-3-0-8x4-ultra) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-10*
