ros2 wireless alternatives
Hi all,
I am working on a a project with the turtlebot3. Both my laptop and the RPi4 on the tb3 have ROS2 Foxy and Ubuntu 20.04.
The issue I am having is that while I am able to do ROS related projects at home, I cannot do it on a college campus. I have worked with IT to get a dedicated IP address to my devices but multicasting is restricted as it is deemed a security issue.
As an alternative, I tried to get a Wireless Access Point (https://www.netgear.com/business/wifi...) as a point of connecting ROS devices with less limitations (and internet). The problem here is that my laptop will not connect to this WAC unless there is internet access through it although the pi4 is able to connect to it even without internet. Now if I connect the WAC to a router and provide it internet, my laptop will connect to it. The funny thing is that I can then disconnect the WAC from the router and cut its internet connect and my laptop will still be connected to it. In addition to not having internet, I am able to communicate with ROS devices through the WAC which tells me that it is possible to use ROS through the WAC and without internet. Unfortunately, I am not allowed to plug the WAC into the campus internet since it is again deemed a security issue, even for a minute.
To cut to the chase, I was wondering if anyone knows why I am not able to connect to the WAC on my laptop when the WAC does not have internet and is there a bypass for this? I am able to do this through windows but prefer not to run ROS through windows. I have also tried to connect to the WAC via ethernet as well without success and I think for the same reason as it refusing to connect via wifi.
If there is no solution for the question above, are there any suggestions to have wireless communication between ROS devices without a router?
Thanks in advance.
