First: Learn to walk before you run.  Meaning, get things working with 
a wired network connection BEFORE you try to use a wireless solution.

Second: It seems that you might be using a somewhat recent version 
of simh since you've got a SHOW ETHERNET command, but it would be 
useful to see the output of a SHOW VERSION command.  The latest
Windows binaries are available at: 
https://github.com/simh/Win32-Development-Binaries

Third: Since you've disabled DECnet, that might mean that all you care 
about is IP so, you may be able to achieve that both wired and wirelessly
if you use a NAT: attachment for your XQ device.
