Every device marked with an asterix is gigabit enabled. Unfortunately, The maximum MTU on my wireless device seems to be capped at 1500. I've enabled jumbo frames on my PC ethernet to 9014 and it seems to communicate fine when linked directly into Bubba. Faster, even.
I 'had' a problem with transfer speeds until I looked into this. I hope this helps someone else.

Also,
trying to activate jumbo frames while you have an active torrent, completely crashes the system, FYI.
