Adding BE63/65 on existing XE75 Pro network
I have a setup with three XE75 Pros, in AP mode - all three connected via Ethernet to my ISP Gateway. My ISP Gateway only has one 2.5G port and three Gigabit ports. The 2.5G port is connected to a 10G Switch, and hence the XE75 Pros are all connected to Gigabit ports.
I am adding a Deco BE63/65 with 4 x 2.5G ports, and want to run the BE63/65 as the Router, connecting one of the ports to the Gateway as WAN, one to the 10G Switch, and the remaining two to the XE75 Pros. The third XE75 Pro will be connected to the Switch. I absolutely hate the ISP Gateway, it is clunky, slow, and with limited functionality. Hence, I want to bridge the ISP Gateway, and use the BE63/65 as the Router providing DHCP/NAT etc.
I know I have to revert the setup to WiFi Router mode, but I want the BE63/65 to be that Router, as it will be the Deco connected to the Gateway WAN.
Do I simply add the BE63/65 to the existing network, or do I need to reset the XE75 Pros?
Do I need to delete the XE75Pros from the app, reset and add them back, after setting up the new BE63/65?
What is the order of doing things?
