I did somehow manage to install nano a couple of weeks back but forgotten how I did it. This reference to W I must admit to being confused by. Obviously openwrt doesn't have a BASH history for me to refer back to.
Got to admit that although I am pretty familiar with APT, PACMAN and DNF compiling is a mystery to me. Are you saying my drivers for the TP-Link adapter will need to be compiled on a conventional system and then transferred to the openwrt on my R-Pi?
I bought this adapter as I read that TP-Link devices were well supported by Linux, I inadvertently took that to mean it would be recognised. So far easy enough with Ubuntu and Mate, each on different computers.
Sure, you are talking about desktop distros with gigabytes of various drivers, but just for x86_64. They have the possibility of storing/using several concurrent versions of a library etc. And a single CPU architecture to compile for.
OpenWrt typically needs to fit everything into something like 6-10 megabytes fo flash space, and does that separately for 30+ mobile/embedded processor architectures. That means a highly tailored toolchain for cross-compiling stuff differently for each CPU variant.
Now you need a driver for Raspberry Pi (of which various versions use slightly different CPUs), compiled to match the exact kernel in the OpenWrt revision you are using, plus the exact C library version used in kernel and user-space compilation. Totally different than the x86_64 with no limit on storage space. Sadly.
It is all a learning curve. The openwrt for the R-Pi recognises nicely the Pi onboard wifi and I used the setup as a project to make a wifi router. Worked nicely but the Pi WiFi module has obviously limited range.
The TP-Link adapter is merely an experimental project to see if and how much better range I end up getting.
Where did you see these references? I can't see the reference to rtl8814au and can't find it in the Luci software database. Installed kmod-mt76x0u via Luci but adapter still not working but, as mentioned, shows up with lsusb.
Annoyingly I bought this device as I read up and saw a report that TP-Link support Linux well. Think the RaspberryPi (which is what I have opeen-wrt installed on) use Broadcom chipsets so the wifi shows up no problem.
