Built-In WiFi and Phone Service

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.

Arris TG862G Compatibility

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.
