Well it seems to be a Pro problem... as all else is fine.
So.... what model Pro is it ? - what year/size and what OS Is it running? Have you tried connecting it to the Hub on an ethernet cable ?
To do so, you might need an ethernet->port adapter if the Pro has no ethernet port - I connect my 2012 Pro via a thunderbolt-RJ45 adapter and it works great.
