Hello guys, on my UR10e robot, when I plug the ethernet cable (RG45) the robot does not emit any signal (the orange light which appears on the router), I have changed the cable, the router but it doesn’t work (while the cable and router works on other devices which means the problem is on the robot).
Could you please help me to find out what would be the problem?
Thanks

Have you enabled Ethernet connection in:
Hamburger menu → Settings → System → Network
?

I have connected UR with network couple of times and had never any problems with this. I have no more ideas what can be wrong with your connection ☹

Hello everyone !
As part of my research work, I started working with an UR10e, and I’m currently facing to very same problem : when I plug the Ethernet cable, neither the Ethernet port, nor the switch I’m using are showing any light… On top of that, I also get the “Not connected to network!” error message, and I cannot even change the IP address when switching to static mode 😕
Did you manage to find a solution to this issue with your UR10e ? If so, could you please explain how ?
Thank you in advance for your answer !
Best regards,
Caroline.
