Overview

Editorial opinion

The Beryl AX is a USB-C powered travel router on MediaTek's Filogic 820. It has been supported by official OpenWrt since the 23.05 release, uses the open-source mt76 driver, and installs from the stock web interface.

It also makes a capable small home router: the WAN port runs at 2.5 GbE, although there is only one LAN port.
