My Beaglebone seems to have stopped grabbing an IP from my network… :-/ Yay… Something to troubleshoot. 
@Chad_Olson kind of? I was still using the original version of angstrom it shipped with, so I ended up deciding it was time to flash the most recent build. That fixed it.
I probably should have spent more time figuring out what was wrong in the first place, but… I needed it up and running.
Dhcp… maybe it has issues?
