Have a RB/2011UiAS-2HnD-IN in service bit over year. http://routerboard.com/RB2011UiAS-2HnD-IN
Other day it just quit. Replaced the router. Found out all Ethernet ports died on it. I could still get into it with wifi though to extract config. Anyone else seen this? I am guessing its just shot? Debating whether to replace it with same model or go with CRS109-8G-1S-2HnD-IN for few more dollars.
