I have the exact same issue as this guy: https://forums.tomshardware.com/threads/tp-link-archer-ac1300-not-recognised-by-pc.2655741/ and like this guy, it's my first time posting here as well. However, the fix in the comments doesn't work because I can't install the drivers since neither device manager nor the driver software can detect my card. I have three unknown PCIe devices listed in device manager, none of which are the WiFi card (disconnected to check). I've tried two PCIe x1 slots and neither allow the card to be recognized. The green LED on the card is lit, so it is on. What could be the issue here other than it's defective?
