I have a Deco XE75 Pro setup for my fiber network. Connected to it are two Switches with 3 access points. As soon as I switch to a(nother) AP the Deco doesn't recognise my phone anymore and alerts me...

@Kevin_Z Many people, if not all, with the v1 or V2 router have this problem. I bought mine a year ago and had this problem from the beginning. Please create firmware to fix this. Thanks.
