Well, it definitely was the wireless adapters. I managed to pry my 
daughter's computer from her hands for a while, and set up both laptops 
with cables to my router. Adjacency was immediate. When either 
connection was replaced by a wireless connection (to the same router) it 
went dead as far as DECnet was concerned.

Thanks for the pointer to retrocomputinggeek, nice stuff there
