How do I connect my HP printer to a wireless network?

Question

HP

There is a printer: HP LaserJet Pro MFP M177fw
There is a working wi-fi mesh built on the basis of a zyxel keenetic giga router.
The problem is this: I find a wi-fi network on the printer, connect to it, enter the network password, the printer seems to be connecting, in the information about the network connections of the printer, I see its ip-address, network ssid and mac-address of the device, BUT in Although there is a printer on the router interface (under the same ip and mac), it is grayed out, like a device that seems to be registered on the network, but is currently not within the connection radius. HP drivers do not find the printer, neither by automatic search, nor by search through a specific ip, adding a device through the router interface (entering Ip and mac manually) did not help either.
Resetting the settings on the printer also does not help, reset it twice to default, including network settings.
What to do, how to set up the work?
ps I connected to the printer via cable, everything printed fine

After several weeks of torment with the HP1120w self-disconnecting from wifi, my CEO decided logically that since he doesn’t carry the printer with him (it’s still tied to the power cable), then let the device stand quietly in the corner, connected with a USB cable to the print server and quietly print with the usual way, without hemorrhoids with the much-desired wireless technology.
