TP-LINK TL-WN781ND RTL8188EE
TP-LINK TL-WN781ND V3 (version 3.0) wireless PCIe card with Realtek RTL8188EE chip works on Trisquel 9 out of the box. I'm quite pleased I bought it. The card was cheap, 12 € new.

For many TP-Link WLAN products, their earlier revisions used Atheros chipset but later revisions are Realtek based.
I have some older revision WN781ND PCIe cards (rev. 1.x) which are based on Atheros AR9285.

They should be candid and outspoken about the chip. The buyer only gets
to know afterwards when the purchase is done and over with. Trial and
error. But now we know that V3 works with free software.
It is because most users tend to neglect the (importance of) revision number.

I'd like to have Atheros. GNU/Linux & Intel Skylake with Realtek has a
bug.

WORKAROUND: add pci=noaer (or pci=nomsi) to your kernel command
line:
1) edit /etc/default/grub and and add pci=noaer to the line starting
with GRUB_CMDLINE_LINUX_DEFAULT. It will look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
2) run "sudo update-grub"
3) reboot
