Check if the printer is turned on and connected to the same wireless network as your router. Below are some additional recommendations to resolve the issue:

1. Check that the printer has the latest firmware and software updates installed.
2. Check if the router is blocking specific connections through firewall and other security measures.
3. Reboot the network router to see if this will resolve the issue.
4. Manually enter the printer’s credentials into the list of connected devices.
5. Connect multiple devices to the network and check for any conflicts.
6. Consider adding an extender to the network to help improve the signal.
