SP 4520DN drops off network

[MFPTech]

brand-new SP 4520DN drops off the network.
The printer goes to energy save mode and does not wake up when sending a print job to it.
The only way to print is by turning the machine off and on.
Checked the default network settings
Sleep Mode Timer is 60 minutes
Ethernet Speed:Auto Select: Disable 1Gbps
Any ideas please?
Thanks!

Is wake on LAN enabled? Does the network actually support wake on LAN?

Yes, and check the operation with "powercfg /lastwake"
And look for activity at your "Wake-on-LAN-event", it should be mentioned in the "System event log".

Can be a network issue...
Test It with a rj45 Direct to a laptop, try It with IP adress un port.
Check the driver, if It is a WSD, install the driver from Ricoh.
