Printer began to not work with "Printer off line" comment. Diagnostics don't reveal an

[Handlebar2319]

I have a LaserJet M148.  Wireless devices like Apple AirPrint cannot find the printer.  Desktop Windows 10 computer cannot find the printer.  Monday I factory reset the printer and reattached to home network and uninstalled/reinstalled print software with the USB cable and it started working again.  The printer was moved back to its stand where the USB cable does not reach.  I worked wirelessly for two days.  Now same problem, devices cannot find the printer.  Windows says printer is offline.  My home router shows the printer is connected to the network, same network all other devices are connected to.
