I have the Ryzen variant and it comes with the MediaTek Wi-Fi card which honestly makes me annoyed with the Wi-Fi connections getting disconnected all the time. I'm done with this unstable Wi-Fi connectivity issues. I checked the user manual and it mentioned that there are a few Wi-Fi cards I can upgrade one of which is Qualcomm wcn6856-dbs card but I can't seem to find it anywhere to buy. Can someone help me suggest a resolution around this?

The other available card for the 5425 was the Realtek RTL8821CE available here at Parts-People.
I know about the Realtek card but it seems like a downgrade rather than an upgrade if I could get the Qualcomm card somehow that would be perfect.
Then as an alternative to the card you have now this Intel card at Amazon should be a fit as I believe the slot in your 5425 is M.2.
