I have a network issue.

My brother printer has two network connection possibilties, WiFi or Wired, both have different MAC address. As all my devices use a range of IP addresses from XXX.XXX.002.001 to XXX.XXX.002.019, the printer can use either XXX.XXX.002.015 (WiFi) to XXX.XXX.002.016 (Wired).

On the "Address Reservation" page of the app I can see the WiFi printer in connected, but the Wired one is not, if I then use deco Labs to Ping the wired one it does not show up.

I have tested the physical network connection between the Main Deco and the printer, using a network cable tester all connections are good. This is the path the data takes:- PC > 8-Port Switch > Deco XE75 > 8-Port Switch > Printer.

When using a Brother Printer network diagnostic tool it found the printer but gave the IP address as XXX.XXX.002.216.which is avtually my Eufy Doorbell!!

Oh, one other adnomally - There are two PC's on the wired network, My Wifes and Mine, thankfully my wifes is okay, but more often than not my printer does not see the my NAS on the network. This is the path the data takes  PC > 8-Port Switch > NAS ( For both PC's)

Any suggestion where to look next would be appreciated.

Thanks in advance
