#27906 — Good PCIe wifi cards for Linux?

I've got a bunch of newer desktop PCs running Linux, some with AMD CPUs
and some Intel, that I need to setup with wifi. I'd prefer to use PCIe
wifi cards instead of USB adapters. I also want to use 5G if possible.

Can anyone recommend a good chipset or brand to look for, or ones to
avoid?

The PCs are mostly running Ubuntu, with a few running CentOS.

In the past I've figured that the Qualcomm and Intel wireless chipsets
were good, but someone was telling me that the Qualcomm ones have had
some problems with Linux recently, and that recent Intel ones only work
well with Intel CPUs. However, he hadn't used Qualcomm in the last 5
years or so and he's using an Intel one with an Intel CPU and hasn't
tried it with an AMD Ryzen one. So, his reservations about Qualcomm and
Intel are not backed by any facts that I can see.

Avoid Ralink. It sits in my AMD Debian laptop and kind of works. But
while in some public WIFI zones my Android logs in the laptop won't.

Also heard to avoid Ralink from another Linux user.

I loathe broadcomm too.

You can get much farther with a kind word and a gun than you can with a 
kind word alone.

No personal experience with it, but the list of supported distributions
is extensive. I prefer wired connections for desktops.

Thanks everyone!

I'll give this card from thinkpenguin a try, and I've also ordered a
couple of other cards that use the same Atheros AR9280 chipset to try as
well.

I had originally thought of just using USB Wifi adapters, but was told
that in the past those have "disappeared." :-) Cards actually in the
case are seen as less likely to walk off, although I wonder if the
screw-on antennas wouldn't be tempting? I guess we'll see.

Pretty much every other system is a laptop, with one of those Kensington
locks securing it, and of course no need for wifi cards or even
keyboards and mice.
