Can a Raspberry Pi be, simultaneously:
- a client connected to a 3rd party Wi-Fi access point, and
- an access point that other computers can connect to and be assigned an IP address (so that they can SSH into the Pi without being connected to the 3rd party Wi-Fi network)?
To be clear, there's no need for the computer connecting to the Pi to have access to the internet via the 3rd party access point. My use case is literally so that a computer can open a web page hosted by the Pi, not to use the Pi as a full-service Access Point. I just would rather that my Pi not have to lose access to the internet just to be an AP.
It would also be great if I could turn the Access Point functionality on and off by running a script on the Pi, and tell whether the Access Point is currently on by running another script on the Pi.
