Overview

Editorial opinion

The Marble is a small desktop Wi-Fi 6 router built on Qualcomm's IPQ5018 with a QCN6102 5 GHz radio. Official OpenWrt images can be flashed from GL.iNet's web interface, and the same images work from either firmware.

Its dual-core 1 GHz CPU is modest: without hardware offloading in upstream OpenWrt it suits typical gigabit connections, but not demanding VPN or SQM loads.
