Installing and Using OpenWrt
1

I noticing the frequent CTRL-EVENT-BEACON-LOSS for the system log. and I'm using OpenWrt 19.07.2, r10947-65030d81f3

and my wifi configuration as below:

config wifi-device 'radio0'
	option type 'mac80211'
	option hwmode '11g'
	option path 'platform/ar933x_wmac'
	option txpower '14'
	option channel 'auto'
	option country 'CA'

config wifi-iface 'default_radio0'
	option device 'radio0'
	option mode 'ap'
	option key '*******'
	option ssid 'OPWRT_505_N2'
	option encryption 'psk-mixed'
	option network 'lan'
	option disabled '0'

config wifi-iface 'wifinet2'
	option ssid 'OPWRT_505_N1'
	option device 'radio0'
	option mode 'sta'
	option key '*******'
	option network 'wwan'
	option encryption 'psk2'
	option disabled '0'

My network Topology is OPWRT_505_N2<--->OPWRT_505_N1<--->1st level router to ISP.(Connection between router are wireless)

anyone know what's wrong?

I have the same issue between WR740N (Access Point) 2GHz -> Archer C7 v5 (Client) 2GHz Doesn't seem to interrupt the connection and it only occurs while in transfer which got me thinking the link gets hammered and beacons go missing?

I'm faced with the same problem between two TP-Link TL-WR841N (V8 as Client and v10 as the Master)
Here logs for such situation. When it happens on router, there is no Internet on devices connected to Client router.

Hi, I'm having the exact same problem in a client + AP router:

wpa_supplicant[3035]: wlan1: CTRL-EVENT-BEACON-LOSS

I think it's probably because the AP is too far away from the client? It's just a guess, but it was working properly without the warning in my previous router ( 940N) Right now I'm using an Archer C6.

My config looks like this:

config wifi-iface 'default_radio1'
        option device 'radio1'
        option network 'lan'
        option mode 'ap'
        option ssid '****'
        option encryption 'sae-mixed'
        option key '*****'
        option disabled '0'

config wifi-iface
        option device 'radio1'
        option network 'trm_wwan'
        option mode 'sta'
        option ssid '****'
        option bssid '******'
        option encryption 'psk-mixed+aes'
        option key '****'
        option disabled '0'

try setting beacon interval to 2999 on the repeater master AP.

Thanks for the advice, I already did (I increased the beacon interval of the router my OpenWrt device is connected to), I'll see how it goes.

I have the same problem did you guys fix it somehow?
