I can ssh and ping FROM my base desktop to the laptop.

I cannot ping or ssh to the desktop FROM the laptop.  The laptop also
cannot ping or ssh to other machines on the router/wifi.  The laptop
has no such trouble with external sites or the the Internet, to which
its connection is the same router they all use.

E.g:

<on desktop> ping <laptop> - succeeds
<on desktop> ssh <laptop> - succeeds.

<on laptop> ping <desktop> - fails ("Destination Host Unreachable")
<on laptop> ssh <desktop> - fails ("No route to host")

This was all working a couple weeks ago before OI had to go the hospital.

Hope that clarifies things.  Still so-acting.
