HP LaserJet P1102w_wifi inst. - Printer installation - connection via wifi. Prin

Good morning,

I'm trying to connect the HP P1102w printer via wifi. Software and drivers installed without problem, but a test page did not print. The problem is, I was unable to connect the printer to the wifi network. A blue light is blinking on the printer, which (apparently) indicates that there is no connection. I tried to connect via WPS but without success. The printer is not in the list of devices connected to the router.
I don't know much about computer science, so I am asking for tips on how to solve the problem in a simple way.

Thank you in advance for your help.

Unfortunately, I didn't have a CD. The printer is in use. Software downloaded from hp and installed. There was no problem at this stage. The problem is with the connection of the printer to the router

Thank you, but I did it before ;)

The problem was solved by changing the security settings of the Wifi network.
Changed from WPA-PSK / WPA2-PSK to WPA2-PSK.
