Overview

Also known as the Arris TR4400-AC and includes the SAC2V1A 1GB RAM variant.

The Arris TR4400 v2 is a dual band router provided by Spectrum to customers as the "Wave 2" with model number RAC2V1A. It uses a Qualcomm IPQ8065 SoC with 512 MB RAM and 256 MB NAND flash. There is also a SAC2V1A model variant for the same FCCID and WiFi Alliance certification (WFA71730) but with 1 GB RAM.

RAC2V1A OEM firmware uses OpenWrt Barrier Breaker r1121 build (other reported builds: 1418, 1602, 1782, 1806). The default radio SSID's are MySpectrumWifi{last 2 MAC characters}-2G and -5G. The SAC2V1A is based on Chaos Calmer 15.05.1 (r35193) and the back label references a QR code to use the Spectrum app for setup. The default radio SSID nomenclature changes to SpectrumSetup-{last 2 MAC characters} and OpenWrt installation is the same for the hardware and SSH access, but requires different steps using the serial port.

DFS support was added with an FCC Class II Permissive Change request on 12/20/2017.
