I have the Asus rog strix z270e. I tried the built in wifi and it sucks so I bought a PCIe wifi card. The card keeps losing packets when plugged into the motherboard and when I check the signal strength it only gets 82 percent while the built in wifi gets 100 percent but is slow since it is a cheap built in card. So, do motherboards "bottleneck" PCIe wifi cards or do they just do better with the built in card? Anyone know a good motherboard that has a built in Intel wifi card that is around 200 bucks or less?
