Sorry if wrong catagory, the AC1200 doesnt appear in the 'model' slot for the forum. I just bought the AC1200 pci expansion for my PC and the speed are slow. My laptop gets 200-300Mbs whereas my PC gets 15 even tho they are both as close as they can be to the router. I feel my card isnt even attempting to use 5ghz signal but i am unsure. Its got the latest drivers

Hi, Thank you very much for your time and patience.

I think the model number might be Archer T4E-https://www.tp-link.com/en/home-networking/pci-adapter/archer-t4e/

It is suggested to refer to this link to check the current wireless link speed first:

Then please install the following driver to see whether it helped or not:
