I recently added an AP One AX Lite to my setup. I have a MAX BR1 Pro 5G that acts as the controller. So far twice when I powered up the AP only the 5GHz band was available.
Power-cycling the AP brought the 2.4Ghz band back but at the rate this is happening this is a problem, especially in a vehicle where power is cut an restored all the time.
The first time this happened the AP was on firmware 2.9.4 and I was using the 12VDC input, since then I updated to 3.9.4 and switched to PoE but it just happened again.
Has anyone else experienced this? Is there anything I should do?
Is your WiFi configured with 2.4GHz and 5GHz SSIDs being the same? Or do you have separate SSIDs for each frequency?
how are you determining if the 2.4GHz band is or is not working – are you asking the device itself over the GUI? Or are you testing using another device?
Some client devices will prefer the 5GHz frequency if it’s available (and others may do the opposite).
I’ve never used an AP One AX lite, just AP One Minis (and Balance One, and several BR1 models…) and I’ve never seen them boot up with a missing 2.4Ghz SSID, so this feels unusual.
you need to figure out if the radio is on or off. have you looked at the device logs? have you tried WiFiMan app? i have found some very old devices can’t handle wpa3 so when i updated my networks to wpa3 i had to make a separate ssid for old devices with wpa2.
