The printer has ceased to be visible on all computers via wi-fi through a router - what to do?

Question

ASUS

The Samsung printer is connected to the Asus router, the printer is configured over the air on several computers. Further, everything is as always: "Well, yesterday everything worked, but today everything fell off."
Reboots didn't work. What else could there be? The printer via usb directly to the computer works. Wi-Fi separately also works with computers.
Can't do anything physically? I'm not in the office. He advised me to turn off the router and restart the Asus printer installation program on each computer.
Maybe there are other pitfalls?

Answer 1

If the printer is not visible on the network, then the problem may not be with the network, but with the printer. Does it ping by IP? Try resetting the printer to default and setting it up again :)

Answer 2

try the install disk again

Answer 3

Reset settings (update printer software if possible). Reinstall the drivers using the network printer search.

Answer 4

I asked. Possibly broken. Refresh. By. WPS must connect. Check on your smartphone via Wi-Fi Direct
