Clients unable to connect to WiFi SSID when using dual 2.5 & 5g. Only able to connect to 2.5 alone.
Essentially, I have been running to WiFi SSID's. SSID A runs with 2.4 & 5g bands. SSID B runs with 2.4 only. Up till a few weeks ago, there were no issues with connections to either ID. I have A for most clients. B is for those items that can only function on the 2.4 channels.
Suddenly, I am having issues with clients being unable to connect to the dual bands SSID. Using a WiFi analyzer I have noticed a hidden SSID that matches the exact frequency of the dual channel ID.
The only new variable I can think of would be that I ran a new line for eithernet to an office. In order to run this line I needed to add a new switch to provide PoE for the AP while delivering access via cable to the office.
I'm using a EAP660HD(US) v 1.0 on the main floor and an EAP610(US) v2.0 on the subfloor.
I only have about 20 or so clients running on the WiFi so it's not overloaded.
Network layout for is as follows
Router -----> Unmanaged PoE Switch (Switch also connects to other clients but they are all hard wired)
