Hi all,
We’re experiencing a recurring issue with the Intel Dual Band Wireless-AC 8265 Wi-Fi module on the Jetson Nano Developer Kit (JetPack 4.x). The chip frequently restarts during operation, leading to Wi-Fi disconnections and runtime kernel errors.
System Details:
- Platform: Jetson Nano Developer Kit
- Wi-Fi Chipset: Intel Dual Band Wireless-AC 8265
- Driver: iwlwifi
- Kernel: [4.9.201-tegra]
- JetPack Version: [JetPack 4.5.1]
1. Runtime Logs
We see the following kernel logs during runtime when disconnection occurs (note: this is not every time when disconnection happens):
