In order to help the meshing of different WiFi as WAN compatible devices, it would interesting to have a fully secured WiFi as WAN deployment working as following:
In incontrol, activation of the request and level of security.
create a specific wifi for meshing (with autogrenerated passwords etc)
configure the WiFi WAN to log on such SSID if found
update routing tables to allow the mesh as backup if cellular or local WAN are not sufficient
This would be highly useful for events or quick emergency response deployments
Please ask if anything is unclear.
