I’m in the process of moving in to a bus. I have a number of devices that want a permanent network in place, however I want the ability to connect the bus to OTHER wireless networks in order to receive internet access and pass that on.
Basically my ideal scenario is I have my phone autoconnect to wifi when it’s around the bus, allowing me to control lights/power/inverter etc, and can then access a web portal by which I point the bus router at another wifi network (for example while parked beside a friend’s house) and log in to that network and using it for web access.
I am a capable tinkerer, with enough coding knowledge to look at someone else’s code and tweak it to work, but probably not build anything new. Is there a raspberry pi/Linux package that allows something like this? Any obvious solution to look towards?
Wireless bridge it what you want.
It connects as a “client” to a wifi AP, and then has Ethernet ports for your router and other devices to connect to.
And sure, you could setup a raspberry pi to do that, or you could just get a commercially made one.
Most “travel routers” have such a function built in.
Many open source router firmware does too.
There are also devices made that are inherently designed with that as their primary functions.
