Additionally, here is the log from ku_rd on successful connection of the scale: [I] Apr 25 00:46:52 ndm: Network::Interface::Mtk::WifiMonitor: "WifiMaster0/AccessPoint1": STA(d0:49:00:2f:c1:91) had associated. [I] Apr 25 00:46:52 ndm: Network::Interface::Mtk::WifiMonitor: "WifiMaster0/AccessPoint1": STA(d0:49:00:2f:c1:91) set key done in WPA2/WPA2PSK.

A WiFi scale (probably ESP32 based) uses 2.4 GHz to sync. The problem is: the device connects successfully to the old Keenetic Ultra2, but can't connect to the modern Keenetic Challenger SE (KN-3911) with the same WiFi settings. ku_rd config fragment: interface WifiMaster0 country-code DE compatibility BGN rekey-interval 86400 up ! interface WifiMaster0/AccessPoint0 rename AccessPoint description "Wi-Fi access point" dyndns nobind mac access-list type none wps authentication wpa-psk ns3 xxxxx encryption enable encryption wpa2 ip dhcp client dns-routes ip name-servers ssid Deutschland25 wmm rrm up ! interface WifiMaster0/AccessPoint1 rename GuestWiFi dyndns nobind mac access-list type none authentication wpa-psk ns3 xxxxxx encryption enable encryption wpa2 ip dhcp client dns-routes ip name-servers ssid Umbreon rrm up !

It looks like some new features are incompatible with old legacy wifi clients. During non-successful attempts there are the next entries-set in the log: [I] Apr 21 23:18:28 ndm: Network::Interface::Mtk::WifiMonitor: "WifiMaster0/AccessPoint1": STA(d0:49:00:2f:c1:91) had associated.

[I] Apr 21 23:18:32 ndm: Core::Syslog: last message repeated 4 times. [I] Apr 21 23:18:33 ndm: Network::Interface::Mtk::WifiMonitor: "WifiMaster0/AccessPoint1": STA(d0:49:00:2f:c1:91) had deauthenticated by AP (reason: previous auth no longer valid). Can anyone suggest which setting add/remove to achieve compatibility?
