Yes, sure!

I have installed the following firmware but keep getting the error (016–426).

The laptop cannot find the printer online.
I have a PC that accesses the internet using the phone's hotspot.
The PC is connected to the Xerox printer with an ethernet cable.
There are no cables between the laptop and Xerox.
The laptop has Windows 11 while the PC Windows 10, both very up to date.
After this update I can print from PC but not from laptop.
The WiFi receiver is properly installed behind the device.
I'm not very experienced. Can you help me?

Hello there,

Do you have the wifi adapter installed at the back of the device like in the video?

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)
Released: 07/12/2022

The printer works perfectly with the ethernet cable.
