USB wi-fi adapter drivers. HELP! [duplicate]

New linux user here, and i have no idea how drivers work, specially ones that are not included in the kernel. I am on Ubuntu 20.04 and the lsusb gives me

Bus 001 Device 004: ID 2357:0115 TP-Link 802.11ac NIC

So the issue is with the official linux driver provided by the manufacturer: https://www.tp-link.com/us/support/download/archer-t4u/#Driver Following the installation guide: https://static.tp-link.com/2018/201812/20181207/Installation%20Guide%20for%20Linux.pdf i get 2 errors after the make command:

is there a way to correct the 2 errors ? since it doesn't create any .ko file as it should

and also if successful copying the resulted file to /lib/modules/[kernel version]/kernel/drivers/net/wireless/ is the way to go ?

You can install drivers from Cilynx's GitHub repo for RTL88x2BU that has worked well for me.

As detailed in the repo, I've installed the drivers using DKMS installation method:

git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu
