If this was working for a long time and then quit it's likely because it went to sleep and when it turned back on I got a different IP address from the router.

if no smartphone the wps pushbutton method is described on page 56 of the users manual. i think you have only 2 minutes to get back to the printer and set it up once you press the wps button on the modem.

Let me know if you have a flex system (WiFi boosters or repeaters) as the setup is much more complicated.

Once you get it connected and working then log into it and see if you can set it so it does not sleep.

The printer is waking up from sleep and getting a different IP address than it had and your PC cannot communicate with it anymore. A quick fix is to set the sleep to off or never. Access the printers embedded web page and set sleep to off or never.

If the printer keeps changing it's IP address then a change to the modem is necessary. The printer needs to be assigned a fixed IP address that is reserved and does not change. This is necessary on flex networks (multiple wifi booster / repeaters)

Assigning a fixed or reserved IP address is done in the modem as part of DHCP configuration.

First get a network report from the printer so you know its IP address or Mac address
Log into the modem and look for the DHCP server. Find the IP or Mac address of the printer and make it a fixed IP address.
