Absolutely not outdated.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Outdated for Linux Intel, still valid for Broadcom, probably not so bad for somewhat recent Realtek and AMD/Mediatek (last I’ve read is that Mediatek WiFi hardware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.

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.
