@Alexandre. Thank you. In fact when I was in AP mode I didn't have any problems. But now I need a configuration working in router mode. I could also connect the printer to the 192.168.1.xxx network...

Wifi router is a Tp-Link Deco M5 (router mode, wireless network 192.168.68.xxx, isp router eth 192.168.1.140) My printer is an Epson xp 7100 connected via wireless to the Deco router (192.168.68.108)...
