Can anyone recommend a device for running OpenWrt in a car/camper?
Maybe look at a travel router like one of the GL inet devices
A cheap alternative: ZBT WE826
Or Teltonika RUT955, almost industrial quality.
you can use TP-Link TL-WR902AC
Thanks for pointing out the Teltonika RUT955... just bought one. Wondering how to connect it up in a car ie. power and aeriel ....
