Pretty much any device you have can be connected to a RJ45 ethernet connection with a suitable adapter. I have them foy all my Apple equipment to connect to either... USB3, USB-c, T'bolt, Firewire or Lightning - all connect flawlessly. Get one for your laptop and test it.
What I am trying to ascertain is whether there is a faukt on your Hub/Network connection - or just poor or interference on wifi from say... microwaves, DAB radio, external radio sources etc.
Different solutions apply to those two possibiities.
What Hub model is it and what VM BB Package are you on?
