Hi Tim,
I'm trying to make tl-wn823n v2.0 work on arch linux. I followed the this[1] guide. [1]https://bbs.archlinux.org/viewtopic.php?id=218152
Have you also been following this guide in the wiki? https://wiki.archlinux.org/index.php/Network_configuration/Wireless
I was able to install the driver:
$ lsmod | grep 8192 8192eu 1544192 0 cfg80211 851968 1 8192eu vmw_vmci 81920 0
The forum thread you reference is from 2016 and says Something interesting, support for this device will be in the 4.9 kernel using the rtl8xxxu driver, then you won't need any external drivers anymore It's not clear what parts you have done from that thread, and whether you'd be better off ignoring it and following the wiki. -- Cheers, Ralph.
