What type of PC or laptop do you have? Is the AX200 adapter original or was it added after you built or bought the PC? What type of wireless router or access point are you trying to connect to? Are there many objects such as walls or doors in the path between the router and the PC? Is it possible there are households close enough that their wireless devices could be interfering?
