Hi, I don't think hostapd matters much, because NetworkManager uses wpa_supplicant's AP functionality (of course, wpa_supplicant and hostapd are the same project, so they share code). Is the quoted log from from wpa_supplicant? I'd suggest, to enable level=TRACE logging for NetworkManager (see [1]) and debug logging to wpa_supplicant, and look at the logs. If possible, provide them here. [1] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/contrib/fedora/rpm/NetworkManager.conf#n28 Sometimes, changing the MAC address trips up supplicant or the driver. You could disable that, see: https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/nm-conf.d/31-mac-addr-change.conf?id=8dfa903a9d6d558cac684c9a3b15bb685a369aad what's the output of `nmcli -f all device show "$WLAN_DEVICE"` ? best, Thomas
