Printer WiFi Connection Drops

I have a Epson ET-4850 printer with a wireless connection to my computers. After a period of time, the printer is apparently dropped from the wifi network. Connection is restored only if I power cycle the printer off & back on. This was never an issue with my previous printer of 15 years. If the issue is related to the power saving function of the printer, the maximum "awake" time is only 60 minutes.
Software & firmware are all up to date. Deleting & adding the printer back to the computer is of no help.

I would really appreciate any suggestions to resolve this problem. Thank you so much.
