We currenly offer wifi service via LTE backhawl on our campus shuttle buses. We have been using AP70s as RAPs for a while now but we kept running into an issue where the AP70s would loose their config.
So, we attempted to replace one of the APs with a AP225 and we still ran into the same issue after about 2 weeks of operation.
As for a physical setup, the AP is powered by a Axis T8122 POE injector getting 12V from the ignition of the bus. It should also be noted that the bus is turned on/off many times a day.
As for why we chose these AP70 models, we are using both ethernet ports, one for uplink, one for a raspberry pi with GPS tracking, and we use the USB port to power the raspberry pi.
So what I'm looking for is to understand why the AP is loosing its config. Something wrong with it going on/off so often? Bad voltage coming through the POE? Could the AP be getting turned off during boot and that could flush the config?
Thanks
