Persistent WiFi Disconnection on JetPack AGX Orin Developer Kit

[yahya3]

JetPack Version: JetPack 6.0 rev2
Hardware: AGX Orin Developer Kit
Storage: JetPack image flashed on NVMe (SSD)
Kernel Version: 5.15.136-tegra

Description:

I am experiencing a consistent issue with WiFi connectivity on my AGX Orin Developer Kit. The WiFi frequently disconnects, affecting the stability and performance of my applications.

Steps Taken:

• Reflashed the JetPack image on the NVMe SSD using SDKManager v2.1.0.11682.
• Ensured all system updates and dependencies are installed.
• Checked WiFi signal strength and network stability.

Despite these efforts, the problem persists, and my WiFi connection is still unstable and keeps disconnecting. Any assistance or suggestions to resolve this issue would be greatly appreciated.

Thank you.

Any dmesg to share after the error happened?

@WayneWWW Same issue and did try re-flashing but no luck. Attached is the kernel log, just the only difference is that I am running real_time patch.

Could we fallback to the simplest kernel and share your method to reproduce this issue?

I don’t see error log from wifi card in your log.

This is strange, as at this time the keyrings would not accept password for the WIFI until I restart, I can change the kernel to default and give you update once this happens.
This usually happens once in 2 or 3 days.

@WayneWWW This happened again today, currently on stock kernel. Please see kernel log.

Looks like kernel does not report any error again. This means this disconnection is a normal negotiation result. Maybe syslog will tell why the disconnection happened.

@WayneWWW

syslog

I just restarted the system, possible to still get the old syslog in /var/log ?

[WayneWWW]

Yes, syslog record should be there unless you deleted them.

[anath]

Please see syslog file.
syslog.txt (65.5 MB)

[WayneWWW]

Basically I won’t read that 65.5 MB file. This file size already told it is like a dictionary.

You have to locate which day and which time that disconnect first and parse that log out.

[anath]

Please see this new log, roughly about this time it went down

This log is still too long to tell.

At least identify whether you are talking about an issue happened around 10:35 or after the next reboot in 11:11.

I saw some disconnection from that “Fisher-USA” AP after 11:33 but not sure if this is the disconnection you are talking about.

[anath]

@WayneWWW Apologies on my end, yes there was disconnection at 11:33 and it never came back online again. Issue happened about 11:11

I am also using an AGX Orin Dev Kit 32GB and the exact same issue occurs. The wifi randomly disconnects, and then when attempting to reconnect, it doesn’t accept the wifi password. Rebooting the jetson solves it temporarily until it happens again (every 2 to 3 days).
