Created attachment 285451 [details] zip file of iwlwifi tracing log Hi, I'm using backport driver for Intel AX200 on Nvidia Jetson Nano. After I installed the driver, the wifi can be detected but cannot connect to the hotspot. My Jetson Nano Developer Kit SD Card Image is 4.2.2 . The dmesg log result show as below: [ 3.676319] Loading modules backported from iwlwifi [ 3.676323] iwlwifi-stack-public:release/core45:7841:bcd11ac8 [ 4.558600] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002) [ 4.572557] iwlwifi 0000:01:00.0: Direct firmware load for iwl-dbg-cfg.ini failed with error -2 [ 4.581634] iwlwifi 0000:01:00.0: Falling back to user helper [ 64.651799] iwlwifi 0000:01:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 43.2.23.17 [ 64.651811] iwlwifi 0000:01:00.0: Found debug destination: EXTERNAL_DRAM [ 64.651814] iwlwifi 0000:01:00.0: Found debug configuration: 0 [ 64.652867] iwlwifi 0000:01:00.0: loaded firmware version 48.4fa0041f.0 op_mode iwlmvm [ 65.255728] iwlwifi 0000:01:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340 [ 65.269591] iwlwifi 0000:01:00.0: Applying debug destination EXTERNAL_DRAM [ 65.270520] iwlwifi 0000:01:00.0: Allocated 0x00400000 bytes for firmware monitor.
