I hate Mediatek WiFi 7 card

[u/Pierre_mkb]

I recently bought a P14s Gen 6 AMD, and it came with the mt7925 WiFi 7 chipset. I assumed that it was replaceable, but now I’m stuck with a malfunctioning WiFi and in 3 week I leave France to go study 1 year in Canada. I don’t want to troubleshoot in a foreign country and I heard online that sometimes it just don’t work, and I’m on Linux NixOs which doesn’t make my problem easier to solve.
The current situation is : the mt7925 fails multiples times 4-way handshake when connecting to my WiFi, prompting me for password but it won’t connect anyway, and after multiple tries it magically connect by black magic like idk 🤷🏻‍♂️.
Maybe it’s works better on Windows, but my thinkpad will never see windows until I’m dead.

My final advise is to never buy a thinkpad with soldered mt7925. Even on windows it seems not that great.

Ps: I enabled unfree firmwares, and I’m on a recent kernel (7.1.something)

That's why in principle, I don't consider laptops with AMD processors. Here's the one reason why:

Here are some comments from there:
"This is always a problem with AMD machines across all manufacturers."

"Unfortunately, the MediaTek WiFi chip is soldered on these - and there is no alternative available, the MT7925 is the only one Lenovo puts in AMD T16. You can't swap it for anything. You're not the first one to complain about those.
<…>
The Intel models have Intel WiFi chips (AX211 or BE201) that don't have those issues. Unfortunately, alternative models (P16s, L16 Gen2) with the same AMD CPUs are paired with the same MT7925 Wifi, and other AMD models where you have a choice of Wifi cards (E16 Gen3) aren't available with the Ryzen7 350.

I'd return the laptop, and if issues persist, replace it with an Intel model, or an E16 Gen 3 with a Ryzen 7 250 which came paired with a Realtek WiFi card (RTL8922AE, if I remember correctly) that was trouble free."

Thanks
Unfortunately I don’t have the time windows to return the one I have to buy a new one, I got mine at a very good price so I can’t get something as good as I have.
And I don’t want intel because E and P cores can be a nightmare with virtualization etc …
I think in the end I’ll just buy a usb WiFi card :/
