I have just moved to a house where I can't get an Ethernet connection to the broadband 'modem' so I need to finally adopt a wifi setup to connect my two desktops and random Raspberry Pi and Arduinos to the 'modem' & the internet. That raises two problems: I don't know anything about wifi except for my Acer Nitro 5 just asked for a password then worked. The only brand of wifi hardware sold by any of the local shops is TP-Link brand. I have one of their Archer T3U AC1300 dongles that is listed as might work. I tried to build it on the laptop with aur but the package errors with 'ERROR: Missing xxx kernel headers for module rtl88x2bu/5.13.1r179.a2ac3b2' where xxx is one of a list including sys, srv, boot, home, etc, bin, rootfs-pkgs.txt, desktopfs-pkgs.txt, run, usr, lib, dev, lost+found, lib64, tmp, opt, proc, mnt, sbin, var, root I tried to build the driver on the desktop but makepkg immediately crashed because I have no internet connection. The laptop is 6 months more up-to-date than the desktops that have been in storage. What I'm looking for is 1. a way to build the driver for the Archer T3U and/or 2. the make/model of a dongle that will work and/or 3. other options? I have tried Ether of Power setup but the basement my daughter has relegated me to is on a different circuit to the rest of the house. please help mick in the dungeon
