If there any reason why there are no 802.11AX network adapters (except for Intel AX200)?
There are tons of routers available with 802.11AX already but nearly no client devices. From what I remember at the time of release 802.11AC, there were a bunch of adapters released along with the routers.
I specifically don't like the Intel devices because you can't use them as Access Point mode in 5G bands.
