Been a long term user of Linux, mainly Debian type distros but I am new to Open-WRT.
Installed it on a Raspberry-pi 3B as a project, all working fine, ethernet connected to network and onboard wifi acts as an Access Point.
To inprove range I bought a TP-Link AC600 Archer T2U plus, it seems to use the rtl8812au driver and I have installed that using the luci interface. Still not recognised.
Do I have to install any firmware? There doesn't seem to be anything specific for this driver.
