Saves money (eliminates monthly modem rental fee). *by N***E on May 29, 2018* 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 :) ### ⭐⭐⭐⭐⭐ Stable and reliable *by A***R on May 5, 2019* Very stable. 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). --- ## 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.sn/products/34242415-tm822-series-tm822a-touchstone-docsis-3-0-8x4-ultra-high](https://www.desertcart.sn/products/34242415-tm822-series-tm822a-touchstone-docsis-3-0-8x4-ultra-high) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
