Hello Bagas, The distro I am using is: Jetson Linux 35.4.1 which is is part of JetPack 5.1.2 Supported Linux Kernel version: 5.10 LTS aarch64 sample root fs built from: Ubuntu 20.04 When I asked Nvidia directly, their response was "Most likely it could be wifi driver issue because it gives." These are the drivers being loaded: rt2800usb 36864 0 rt2x00usb 24576 1 rt2800usb rt2800lib 122880 1 rt2800usb rt2x00lib 77824 3 rt2800usb,rt2x00usb,rt2800lib mac80211 811008 3 rt2x00lib,rt2x00usb,rt2800lib cfg80211 724992 2 rt2x00lib,mac80211 I've not worked with driver code before, so I am out of my element here. I saw in the git history for rt2800usb some changes went in since I was using the USB wifi adapter on an older system that has a linux version older than 2019 (when the OS was compiled and flashed on the machine). And maybe something else is broken somewhere. Just not sure how to help figure out where this is all broken.
