Cox Approved Modem List 2026: Cox-Certified Modems That Work
The full Cox approved modem list for 2026. See every Cox-certified DOCSIS 3.1 modem and gateway, which one fits your plan, and how to activate it.
The Arris TG862G Touchstone Telephony Gateway is a DOCSIS 3.0 cable modem with a built-in WiFi router and two-line VoIP phone service in a single device. It supports download speeds up to 343 Mbps, four Gigabit Ethernet ports for wired connections, and 802.11b/g/n wireless for devices throughout your home or office.
This gateway also includes a Lithium-Ion battery backup that keeps your phone service running during power outages — a feature that's especially useful if you rely on VoIP as your primary phone line.
The TG862G combines three devices into one: a DOCSIS 3.0 cable modem, a single-band wireless router, and a two-line VoIP telephone adapter. The 802.11n WiFi handles everyday tasks like streaming video, browsing, and downloading files without needing a separate router. Two phone ports on the back of the unit let you connect standard phone handsets for VoIP service through your cable provider.
This model is compatible with Comcast Xfinity for plans with download speeds of 343 Mbps or less. It also supports Comcast phone service in most areas. However, some regions may require manual activation by Comcast tier 3 technical support due to firmware differences between this retail version and Comcast's rental version. Always call your provider before ordering to confirm this model works with your specific plan and service area.
