with Murata module integrated to IMX8Mmini WPA3 client connectivity to Netgear-RAX50 failing

Static hostname: imx8mmevk

Operating System: NXP i.MX Release Distro 6.1-mickledore (mickledore)

Kernel: Linux 6.1.36+g787413eb2b1c

NXP Wlan Driver: PCIE9098--17.92.1.p136.131-MM6X17408.p2-GPL-(FP92)

Wpa_supplicant version: 2.10

Based on below supplicant logs, WPA3 authentication is failing

1677841994.237147: mlan0: WPA: Failed to select authenticated key management type

1677841994.237164: mlan0: WPA: Failed to set WPA key management and encryption suites

Supplicant conf file:

ctrl_interface=/var/run/wpa_supplicant

Dear @NaveenBodagala

The wpa_supplicant configuration you are using is slightly different from the one we advice in our documents.

Could you please test below reference WPA3 SAE configuration ?

ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 update_config=1 network={ ssid="NETGEAR20_5G" scan_ssid=1 key_mgmt=SAE proto=RSN pairwise=CCMP group=CCMP psk="1234567890" ieee80211w=2 }

Please also note that UM11512 (i.MX8Mnano specific documentation) is not maintained, and you should rather refer to:

- UM11483 Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Linux OS - User manual

- UM11490 Feature Configuration Guide for NXP-based Wireless Modules on i.MX 8M Quad EVK).

Olivier

Dear @NaveenBodagala

Could you also provide Wireshark sniffer captures too ? This is really important to investigate this kind of issues.

Olivier

Dear @NaveenBodagala

From your wpa_supplicant log, it seems that you are using driver 'wext' old interface, instead of nl80211.

Could you please check your moal driver parameters to make sure you have cfg80211_wext=0xf, and host_mlme=1 parameters set ?

In case you are using mod_para=nxp/wifi_mod_para.conf, then /lib/firmware/nxp/wifi_mod_para.conf should contain:

PCIE9098_0 = { cfg80211_wext=0xf max_vir_bss=1 cal_data_cfg=none ps_mode=1 auto_ds=1 host_mlme=1 fw_name=nxp/pcieuart9098_combo_v1.bin } PCIE9098_1 = { cfg80211_wext=0xf max_vir_bss=1 cal_data_cfg=none ps_mode=1 auto_ds=1 host_mlme=1 fw_name=nxp/pcieuart9098_combo_v1.bin }

Olivier
