Bad question.

Recently I had to choose and buy a USB WiFi adapter suitable for
making a software access point. And this is in a semi-rural area, so
almost no interference from neighbors. So I thought, let's make sure
that the USB bus is not a limiting factor. I.e., the requirements are:
USB3, 802.11ac or ax, can act as an access point in Linux, can
actually be bought here in Russia. Result: all (and yes I mean "all",
100%) of USB3 WiFi adapters available in Russia (according to
market.yandex.ru, which aggregates almost all major shops) are based
on various unsupported-in-mainline Realtek chipsets (RTL8812AU,
RTL8814AU, RTL8812BU). So there is no exception. You can check this
yourself by going through this product list, it's not that long:


The two adapters (TP-LINK Archer T4U Plus and D-link DWA-182/E1) that
are not known to wikidevi.wi-cat.ru can still be identified as
something Realtek-based by downloading Windows drivers.

I ordered a (Mediatek-based) Alfa Networks AWUS036ACM adapter from
Amazon, but it took way too long to arrive (it did, eventually, long
after I have given up, that's why the local shopping attempt).

So I ended up buying a TP-Link Archer T3U v3.2 in a local shop and
using it with a driver from https://github.com/cilynx/rtl88x2bu, and
it does yield throughput higher than the theoretical limit of USB 2.0.
