Have you tried it? It's horribly slow.

I've tried it.

I've had it be horribly slow, wickedly fast, and also absolutely fail to work at all.

The wickedly fast method seems to involve the two devices forming an ad-hoc WiFi network -- just for themselves. 802.11ac/ax is pretty darned fast when there's no competition, on a network with exactly two nodes, and when those two nodes are separated by only a couple of feet.

IIRC, this is not the default mode of operation.

I use it all the time. I guess I'm just patient :-)
