Extremely outdated, but would still work with fingerprint sensors or NFC readers

Absolutely not outdated. I had a horrible time getting my hands on a working driver for the WiFi card in my brand new laptop last year. Horrible enough to resort to Ubuntu and even that gave me the finger. When I finally had it working I had to manually rebuild the damned thing each kernel update because I couldn’t convince DKMS to do it automatically. Had to wait two or three kernel releases for the card to be supported ‘out of the box’.

So no, fuck WiFI drivers in Linux. If it is not in the kernel and the manufacturer doesn’t provide one, don’t expect fun times.

Outdated for Linux Intel, still valid for Broadcom, probably not so bad for somewhat recent Realtek and AMD/Mediatek (last I’ve read is that Mediatek WiFi hardware sucks in general and disconnects happen on Windows, so the same happening on Linux would be the fault of the Linux driver).

EDIT: Accidentally wrote Linux instead of Intel.

In my cause it was actually a newer type of Realtek chip. 😞

But was the cause the Linux driver or the hardware? If the fault is the hardware and the experience on Linux is the same as on Windows, it’s feature parity.

If in doubt, get an Intel WiFi card. Even in otherwise not upgradeable notebooks those are usually not soldered on. Also whatever is in a Steam Deck OLED looks like a good pick.

It was the driver, now that support is provided by the kernel it is rock-solid.
Realtek upstreamed their drivers in 2020 or 2021. I got rid of my last notebook with Realtek hardware for unrelated reasons.
Does Intel sell wifi cards that use USB rather than PCI slots? My motherboard doesn’t have the slot for a wifi PCIe card, and I’ve only seen Intel sell those :/

AFAIK the problem is that the chip itself was only developed with the PCI protocol in mind.

I see, that is a shame…
I installed linux on a new pc 2 days ago, had no problem with the wifi drivers. I don’t know if it’s the fact that the wifi is integrated on the motherboard, but it was up and running without any tweeking from me (unlike windows)
I can absolutely confirm it’s still valid for Realtek. I had one using the RTL8812AU chipset that basically no kernel version nor distro provided out of the box, so I constantly had to download a third-party driver from Github and manually patch it via dkms, or use a third-party repository containing the driver package… and then the driver broke so badly that it wouldn’t let me update at all unless I uninstalled it, which left me without the internet I needed to actually update, effectively leaving me unable to update until I could buy another one from Mediatek that’s compatible.

Yeah, and I was explicitly writing about recent chips. RTL8812AU isn’t recent. The very latest Windows driver is from 2018, so the chip itself was released a good while before that.

I know exactly what you had to go through because I had to do the same with mine a couple of years ago but since then for newer chips Realtek started contributing to Linux itself:

which left me without the internet I need

USB tethering your WiFi-connected phone would have worked as stop gap just as well. I had to do that a lot.

RTL8812AU Software - REALTEK

Ahh I see, thanks for clarifying. It seems that where I live mostly only has the older Realtek chips for sale, so I likely mostly had bad luck.

I tried USB tethering, but it wouldn’t work for some reason… I don’t remember exactly what happened, but I think either the phone or my computer couldn’t detect each other.

USB tethering should look on the PC just like plugging an Ethernet cable.
