Ripped and replaced a pair of UBNT APs with a pair of MR44s. I recreated the 2 SSIDs with the same PSKs and all of my Apple Phones, MacBooks, PCs, and Echo devices all connected immediately with no issues.
None of my Roku, Chromecast, LG TVs, or Amazon IoT plugs connected. When I try to directly configure any of those devices, they are not able to see either SSID to try connecting. I tried adjusting settings and also creating a test SSID with open auth 2.4 and 5Ghz, and all speeds allowed but no love. I am running the latest firmware on those APs.
Since this behavior is seen across multiple older clients after the change, I have to believe it is a setting of some sort preventing connection but I can't seem to figure out what it would be. Any suggestions or ideas?
