I found out the hard way that the WIFI receivers built into the motherboards of desktops and laptops almost always suck.
Very often they support only the 2.4 gig WIFI and not 5.0 ghz
The solution I found was the ASUS AC53 USB which should be a maximum of $40. I got mine for $32, and I've seen them for $25. There are at least half a dozen similar USB dongles, but the others sometimes only work with USB 3.0 Some have annoying little antennas the size of a finger attached.
It's sad to buy a motherboard with integrated sound, video, and WIFI.. only to have to go buy a better sound card, better video card, and USB WIFI.
The biggest disaster I ever had was buying one of the most expensive laptops made at the time for $3000. But it only had standard USB ports. The next month, USB 2.0 came out! So I was stuck with a laptop with ultra slow USB and really no fix for that. I had to combine 2 ports into one just to get the USB working at a usable speed.
Then they started with USB 3.0 which is also a problem, because a lot of devices do not function with USB 3.0 even though they claim that the USB 3.0 ports are backward compatible with USB 2.0. Quite often they are NOT compatible. To get around that, expensive motherboards have at least one USB 2.0 port along with the USB 3.0 ports.
