Network Adapter PCIe suddenly not working

Open | Hardware

Have a Trendnet tew-807ech ac1200 PCIe adapter in my desktop.

I just moved and since unpacking my computer, it is unable to detect any networks. Before I moved, part was working perfectly. Move wasn't far and I packed and unpacked everything.

I've tried to clear CMOS by taking the motherboard battery out, then placing it back in.

I've also tried to clear CMOS by using a screwdriver to jump between the pins.

I noticed today that the green light on the PCIe is not on.

I took the PCIe off the mother board and looked for anything wrong with the traces or components on the PCIe board. Even took the heat sink off, couldnt see anything out of the ordinary.

I can't find anything online on this specific issue. Do I give up and buy a new PCIe?

I have a gigabyte a520m s2h motherboard.
