What happened?

I am think of getting the Wifi 7 & Bluetooth 5.4 BE6500Mbps PCIe x1 Tri-Band Wireless Network Adapter Card with MediaTek MT7925 chipset (Integrated Antennas) for my desktop with the POP_OS 22.04. If I am correct this should work? I am thinking of getting this to replace a malfunctioning built in Wifi card on my Motherboard. This is made by HCX-eu.com.

Hi @Bucephalus-44

If I am correct this should work?

POP_OS 22.04

It should work but let's check on some things. Post the results of the following commands:

$ ls -l /lib/firmware/mediatek | grep MT7925

$ ls -l /usr/lib/modules/$(uname -r)/kernel/drivers/net/wireless/mediatek/mt76/mt7921

You are using kernel 6.12 and the driver for the mt7925 was added to mainline starting with kernel 6.7 so you are good in that regard.

Can you provide a direct link to the adapter that you are considering?

FYI: I have a M.2 card based on the mt7925 chip and it works well in my Mini PC. I can't say much about WiFi 7 yet as the most modern wifi router that I have is WiFi 6 capable.
