I have a 11" macbook air and have been working a lot of word and excel documents lately. So now my 27" thunderbolt display came in, I'm happy as can be. But, when I connect my thunderbolt port, how can I prioritize the ethernet connection? It stays connected through my wifi, but if I'm cabling my MBA anyway, I prefer the gigabit ethernet connection (there are well over 70 wifi networks in range around here). Does anybody have an idea? Google and MRoogle didn't help me on this.
