I have an EX220 with a Deco X50 set up in AP mode (plus 2 other wirelessly linked X50s)

I want to switch the X50 back to Router mode.

As I have never done this, I don't know what will happen next: -

Does it simply restart the Deco and all the clients pick up on wi-fi again?

If this works, should I then attempt to remove my EX220 and simply move the ethernet cable directly to the network provider WAN port - I'm happy to lose the ethernet ports on the back of the EX220 by doing this
