Not sure what causes a page setup already created and previously used to not be able to be selected at a later time.  When selecting it, it reverts back to <none>.  Does this mean the plotter changed/is not available?  The network name for the plotter did not change, but the model of the plotter changed slightly.  Is this the problem?  I have the same setup saved in 100's of drawings and assumed that as long as the network name for the plotter remained the same, the setup would continue to work.

Yes, I believe this is because the plotter changed.

Toy  may need to redefine the page setup with the new plotter.

Pain in the butt if you have a bunch of drawings that have the old page setup.

You can save the new page setup in a template file and use a lisp to import the new setup into your old drawings

The only way to get around this is to name the new plotter the exact same name as the old one.
