I watched this video:
Under "tcp/ip" I don't have "WiFi setting". I have the layout in Italian.
I read this:
Impostazioni > Menu Ammin. > Rete/Porta > (Impostaz. TCP/IP, LPD, IPP, Bonjour, USB, Port 9100, WSD, SOAP, SNMP, Server DNS, Servizi Internet, Server WINS, Ethernet, Imp. filtro IP, Impostazioni SNTP, HTTP-SSL/TLS, Com. IPsec, IEEE 802. 1X)
I updated to this version without solving:
Phaser 6510 Service Pack 64.69.91 - (PL7-R10)
The printer works perfectly with the ethernet cable.
