Whelp I've got these old ASUS nodes running; so far the only thing I've found for sure is that node 2 had a broken antenna cable (now repaired) and now they're all working.
I'm wondering whether on site the broken antenna - which critically may be is the backhaul antenna - had been installed improperly but had not fully broken _until_ the node 2 case somehow opened itself right next to that antenna cable. Maybe that finished the cable off, tearing it. I don't know.
(Meanwhile, in node 3, which also opened its own case somehow, the same cable was bent up a bit and kind of wedged into the area where the case separated. that cable is, however, intact.)
