Greetings - I have the Netgear WNDR4300 as my primary router, broadcasting a 5G network a guest 5G network, a non 5G network and a guest non 5G network. My secondary router set-up as an AP is a Belkin N F5D8236-4, and I have a powerline ethernet adapter plugged into port 4 of my Netgear and the second powerline ethernet adapter plugged into port 1 (the 1st port not labeled modem) of my Belkin. I have the same SSID, encryption type, channel and password setp-up as my Netgear however no devices will ever switch to the AP even though it has a stronger signal. If I change the SSID of of my AP to something different than my Netgear then devices will switch to it no problem!
What is it that is preventing my devices from switching over to the AP when it has a stronger signal?
