ASUS USB-C2500
Nominal speed of 2.5 Gb with no problem, stable on large transfers, to be connected to a USB 3 port at least to have the speed.
Under Windows, the driver offers an on-the-fly installation when first used.
Does not heat up,
I recommend, transportable, and adapted to Notebooks on which it is impossible to install a network card.
Of course, you must have switches and routers compatible with this speed.
The price is a bit high, but when it comes to multi-gig, the price suffers.
