summoning both of you since this was mentioned in another thread
There are some edits to be made on https://openwrt.org/toh/tp-link/tl-wa801nd
Specifically: about v5:
- It does have the required flash/ram to run openwrt 19.7 and future versions. The main warning here is misleading, it should only apply to v1 to v4
- It is also now supported in the main branch, starting with 19.7-rc1. I have just upgrades my router sucessfully using https://downloads.openwrt.org/releases/19.07.0-rc1/targets/ramips/mt76x8/openwrt-19.07.0-rc1-ramips-mt76x8-tplink_tl-wa801nd-v5-squashfs-sysupgrade.bin . Building from source is no longer necessary. (I had to do this previously)
I just wanted to make the changes, but was denied.
