I was cursing my MacBook Air's lack of a dedicated Ethernet port today as I was troubleshooting network issues.  I have 5 or 6 different Ethernet dongles (home, office, vacation home, suitcase, grab-bag/briefcase, and maybe another one on a shelf...).  They are all named "Thunderbolt Ethernet Adapter n". I tried to change the names, but it gets even more confusing.

My challenge is the one for the office is configured for 4 different VLANs, and undoing that (especially with 5 duplicate devices) can really be a pain in the ass.  

Next laptop will have a built-in Ethernet port.
