Hello,

I am trying to connect multiple ROS on 3 machines, all running ros melodic

I have the following network :

• ROS MASTER (192.168.31.8) connected to router (192.168.31.1) by ethernet cable
• ROS SLAVE 1 (192.168.31.9) connected to router (192.168.31.1) by wifi
• ROS SLAVE 2 (192.168.31.10) connected to router (192.168.31.1) by ethernet cable

ROS SLAVE 2 is publishing camera frames (1920x1080) at 30 fps on topic /cam/color/image_raw However, my ROS SLAVE 1 accessing this topics, get the frames at a rate at around 0.7fps : too slow to display it on a screen.

I am wondering if I link ROS SLAVE 1 and ROS SLAVE 2 using an ethernet cable and connect the ROS SLAVE 2 to router by wifi only, it would be possible for the ROS SLAVE 1 to access camera frames with a better rate ? and how to setup the network to achieve this ?

I find no topics on this question.

Thanks by advance.

PS : I tried uploading images to better show the network, without success. Images won't display
