802.11r FT reconnect every few minutes

[alphamatic]

Hi,

I've setup 802.11r FT for the last few months on all of my AP.
All AP is dummy AP, only for wireless AP.
All AP running 22.03.3 version.
Some client are android and laptop (no issue)

But, there are 1 client having reconnection issue every few minutes, it's Android Asus Zenfone 5.
This client always try to reconnect again every few minutes. even if it already connect normally, it always disconnected and reconnect after few minutes. Even when the client is not mobile, this issue still appear. Sometimes the client connect to another AP (not the initial AP).

Here are the notification on the client every few minutes.

Here are the logs:

Here is my wifi config:

config wifi-device 'radio0'
	option type 'mac80211'
	option path 'pci0000:00/0000:00:00.0'
	option band '2g'
	option htmode 'HT40'
	option cell_density '0'
	option noscan '1'
	option channel '13'
	option country 'xx'

config wifi-iface 'wifinet0'
	option device 'radio0'
	option mode 'ap'
	option ssid 'xxx'
	option encryption 'psk2+tkip+ccmp'
	option hidden '1'
	option dtim_period '3'
	option key 'xxx'
	option ieee80211r '1'
	option nasid '99999'
	option mobility_domain 'FFFF'
	option ft_over_ds '0'
	option ft_psk_generate_local '1'
	option pmk_r1_push '1'
	option ieee80211w '1'
	option wpa_disable_eapol_key_retries '1'
	option network 'lan'
	option ieee80211k '1'
	option ieee80211v '1'
	option bss_transition '1'
	option time_advertisement '2'
	option time_zone 'UTC'
	option wnm_sleep_mode '1'
	option wnm_sleep_mode_no_keys '1'
	option max_inactivity '3600'

The client is dual band and I separate AP for 2G & 5G band, so there are 1 AP for 2G band and 1 AP for 5G band.

Anyone know what is the issue?
why there are RADIUS message on the log, even I don't setup any RADIUS?
how to resolve this reconnection problem?

I'm wondering about the same thing. I don't even understand what RADIUS is, but the messages appear in the log. I also have some clients dissassociated "due to inactivity" every few minutes. I don't have 802.11r ticked.

It's a normal log message but since you don't have a radius server for auth it doesn't send anything.

Reconnection problem seems is not an issue anymore, at least I don't see it every minutes anymore after I made some changes on the wireless setting.

Here is the config right now on all of my AP (3 pcs 2G band dumb AP & one 5G band dumb AP).

config wifi-device 'radio0'
	option type 'mac80211'
	option path 'pci0000:00/0000:00:00.0'
	option band '5g'
	option htmode 'HT40'
	option cell_density '0'
	option noscan '1'
	option log_level '1'
	option country 'xx'
	option channel '153'

config wifi-iface 'wifinet0'
	option device 'radio0'
	option mode 'ap'
	option ssid 'xxx'
	option encryption 'psk2+tkip+ccmp'
	option hidden '1'
	option dtim_period '3'
	option key 'xxx'
	option nasid 'xxx'
	option mobility_domain 'xxx'
	option ieee80211r '1'
	option ieee80211k '1'
	option ieee80211v '1'
	option ieee80211w '1'
	option ft_over_ds '0'
	option ft_psk_generate_local '1'
	option pmk_r1_push '1'
	option wpa_disable_eapol_key_retries '1'
	option network 'lan'
	option bss_transition '1'
	option time_zone 'xxx'
	option time_advertisement '2'
	option wnm_sleep_mode '1'
	option wnm_sleep_mode_no_keys '1'
	option proxy_arp '1'
	option wpa_group_rekey '13600'
	option r0_key_lifetime '10000'
	option reassociation_deadline '1000'
	option max_inactivity '100'
	option ieee80211w_max_timeout '3000'

Seems this config is fine for me.
