Floodlight Cam Wired Plus cannot see 5Ghz no matter what

I have a TP-Link network and outside I have an EAP610-Outdoor wifi access point. I had my wifi network with one SSID broadcasting in 2.4 & 5Ghz and the cameras connected to it. I realized they were only connecting to the 2.4 Ghz radio though and I have 4 of them outside so that band was fully utilized. I separated the SSID's into two and made one broadcast in 2.4 only the other in 5Ghz only. Now my cameras cannot see the 5Ghz network at all. I have done a lot of searching and tried all of the tips I can find. I made sure my channel was above 52 (I have tried all of them above 52). I have reset the cameras using the setup button. I have tried changing the type of security. I used an iPad and a different iPhone. Tried connecting to a network I can't log into so it would fail first the tried again. No luck. I also realized when it was searching for networks it was not seeing any 5Ghz networks anywhere in my neighborhood so I turned my Xfinity wifi on and the cameras could not see the 5Ghz from it either. I've tried changing the radio's power, bandwidth, etc. The outdoor antenna is close to all cameras and has amazing coverage. I've even tried turning that one off and using one further away and none of my cameras can see it. One camera is brand new and the other three are just over a year old. All have the latest firmware. I've even tried entering the network info, including the exact channel, like it was a hidden network and that did not work. What is going on and what can I do to fix this? These are not cheap devices and should connect to 5Ghz.
