I recently purchased a PCIe WiFi card that claims to be compatible with Linux. I installed it in my Debian computer, but it didn't come with any instructions, which has made the process tricky. After I booted the system, I tried running a few commands like "ip link show" and "lspci -nnk | grep -iA3 net" and found the hardware listed as Mediatek. I followed a link to download the drivers, but it said I wasn't authorized to access it. I managed to get to the site somehow through my browser, but it appears they only provide drivers for Windows, not Linux. I'm stuck and not sure what to do next!

You might not need a driver specifically for Linux. Just make sure your kernel version is 6.7 or higher, as that could solve the problem for you.
It would help to see the full output of your lspci command to get a better idea of what’s happening. Can you share that?
I had a similar issue, but I ended up using a USB WiFi adapter, which worked perfectly on my Zorin OS. If you have one available, it might save you a lot of hassle!
Check if your motherboard has an onboard LAN card. If it does, using an ethernet connection could be a quick fix while you sort out the WiFi card issues.

I can't remember it exactly, but it was something about MediaTek and mentioned WiFi. Why do you need that information?
