> I have no idea what an "invalid group cipher 0x8" is and how to debug that. The message is printed because the Wi-Fi Access point is using TKIP as group cipher. Unfortunately Wi-Fi alliance does not recommends TKIP because it no longer provides sufficient security. https://www.wi-fi.org/download.php?file=/sites/default/files/private/Wi-Fi_Alliance_Technical_Note_TKIP_v1.0.pdf So we recommed to configure the Wi-Fi Accesss point not use TKIP for group cipher. Or, you can rebuild wpa_supplicant without CONFIG_NO_TKIP.
