Lost connection to printer, computer can't find it

Have been  using my Dell Color Cloud MFP H825cdw for a couple of years now. Running Windows 10, with all updates "up to date". Once again, my computer has "lost" the printer. Nothing prints, icon in Control Panel is solid (not greyed out) even though it says "not connected" at the bottom of the screen. After making sure all updates were installed, restarting both the printer and the computer several times each, I deleted the printer from the control panel and took the following steps:

• Turned on printer, made sure wireless "button" is lit up (turned on) and not flashing
• Made sure no other cables were connected to the printer
• Changed "sleep mode" to 30 minutes so printer wouldn't fall asleep during installation
• Downloaded installation software from Dell for this printer and ran it using admin mode, selecting wireless installation, making sure printer "window" stated the printer is connected to my WiFi 
• Dell Printer Easy Install popped up, searched for printer, progress bar reached the far right, then indicated the printer had NOT been found. 
• Made one more pass, then restarted the computer and printer once again
• Ran Dell install software again, trying for "ethernet" connection this time after plugging in cable and restarting printer...still doesn't find the printer 
• Unplugged ethernet cable, restarted printer, ran software again
• The software never finds the printer

My computer is a Dell Inspiron 17R, running Windows 10 64 bit, 8gb Ram, Intel i5-323OM CUP @ 2.6GHz. 

Where to go from here?
