Network config for wifi independence
I would like to set up a ros2 Galactic robot to be resistant against WiFi failure. The robot (Jetson Nano, Ubuntu 20.01) runs all essential nodes locally (e.g. NAV2). RViz or other non essential nodes are running on a laptop. They are connected via a wifi access point.
I want the robot to continue to work correctly also if the wifi connection fails. All local nodes on the robot should continue to work/communicate with each other. As soon as the connection is back, the laptop can pick up its work again. At the moment it seems the the communication between the local nodes on the robot fail to communicate when the WiFi connection drops.
What is the right approach to achieve this?
