N2MH and I have both observed odd behavior with the hAP ac lite when using a 12v battery power supply. Specifically, it has been observed at times, if using the device on 5MHz channels and with a 12v Power Supply, it does not make a link. However, swapping to a 24v power supply it it is linking to other 2GHz mesh devices on 5MHz channel. Keep an eye out for any any weirdness and if you are using a 12v supply, swap to a 24v to see if any change of behavior.
