Ethernet Remote Desktop gets disconnected frequently

Autonomous Machines Jetson & Embedded Systems Jetson Orin Nano

Hi,

I have configured static IP on the Jetson Orin Nano Developer Kit and I am accessing the Jetson via Remote Desktop. Sometimes, the connection gets disrupted and then reconnects after sometime on its own. I have also checked the cables, and the connections are fine. The dmesg log after disconnecting and reconnecting is below.

As I have been using this for more than six months now, could it be because of the ethernet connector on the board becoming loose?

Thanks.

Hi,
Please share which Jetpack version you are using. If you use Jetpack 5 or 6.0GA, you would need to apply the patch to r8168 driver:
Ethernet Disconnects with "r8168: eth0: link up" Message in kern.log During Deep Stream RTSP Streaming - #5 by WayneWWW

Hi, I’m using Jetpack5.1.3. Please share the patch for this version as the linked post is for rel-36 (Jetpack 6.0).

Thank you.

Hi,
We would suggest upgrade to Jetpack 6.1. If you have to stay on 5.1.3, please manually to integrate the patches to r8168 driver.
