Hi there,
A few months ago, I added a new device from TP-Link, and it would be nice if OpenWrt officially supported it. Therefore, I will post updates here on adding support for it.
Info & photos https://wikidevi.wi-cat.ru/TP-LINK_TL-WR850N_v2
This router is very similar to TP-Link TL-WR840 v4 and TP-Link TL-WR841 v13
tl-wr850n-v2.patch for current master:
