How can I connect to a ROS master and the internet via two different networks?
Hello!
I am a student and we are currently working on a project where we use the RethinkRobotics Baxter robot. Our self-made ROS-nodes run on a computer that is connected with the Baxter via a router (the Baxter robot is the ROS master). We also need an inte^rnet connection for our application. Therefore, we connect the computer to a wireless network with an internet connection. This second wireless network is necessary because the University does not allow to connect routers to their existing network.
To sum things up, we have one wired connection to a router to be connected with the ROS-master (Baxter robot) and a wireless network connection to get internet access. Our problem is that we are not able to communicate with the Baxter robot if we are connected with both networks. If we disconnect with the wireless network, everything works fine.
Can anybody help is in that case? Is this a ROS-problem or simply a network setting in ubuntu? We already tried many things but we did not solve the problem.
We are using ROS-kinetic and Ubuntu 16 LTS.
Best regards, Gerald
