I recently assembled a PC with a PRO B760M-P DDR4 motherboard, which doesn't have built-in wireless capabilities. To get Wi-Fi, I installed a TP-Link Archer TXE75E AXE5400 PCI card. However, when I try to update the drivers, the software doesn't detect the card at all. I've heard that my motherboard only supports PCIe 4.0 while the card is PCIe 5.0, so I'm considering setting it to 4.0 in the BIOS. Are there any other troubleshooting steps I should take? Thanks for your help!

Have you looked for it in the device manager? Sometimes, Windows tries to install a generic driver that doesn't work with the card. Make sure it's showing up there; if it is, you might want to uninstall the current driver and try installing the specific one again afterward.
Generally, PCIe devices are backward compatible, so they should work even at lower speeds. Have you checked if the card is properly connected? Don’t forget to plug in the USB header; a lot of Wi-Fi PCI cards need that little 3 or 4 pin cable connected to the motherboard for full functionality.
I did check device manager and found a PCI entry with a yellow exclamation mark. I thought updating the driver would resolve it, but it just disappeared and I still have no Wi-Fi. Any thoughts on what to do next?
