TP-LInk Archer T2U V3 not working on latest SNAPSHOT

redpineapple · January 5, 2020, 7:53am

I have installed the latest SNAPSHOT of OpenWRT x86 and the TP-Link Archer T2U V3 does not work. The module is kmod-rtl8812au-ct
The modules looks like it loads on boot but the dongle green light never goes active.
Have tested in on my laptop where it works fine.

Fixed the install but still no joy. Not even visible in iw list!

Hi, same question on 23.05.5. Package kmod-rtl8812au-ct is installed, but still nothing shows up in "wireless". Or is even package rtl8821au needed? The last one seems to be missing in 23.05.

## USB WiFi chipset information for Linux

Updated as of 2024-12-17.

This document is a summary that includes information about many modern USB WiFi chipsets. If you see errors in this information, please post in Issues.

Not all USB WiFi adapters are created equally.  While the chipset and driver
dictate which WiFi features are supported (e.g. which frequency bands), the
vendor of the adapter is free to decide on the performance of the antenna(s),
the quality of the amp and whether the device requires mode switching and so on.

Try 24.10, and rtw88, if not working, wait for Openwrt kernel to catch up.
