2.4 GHz suddenly stops working


#1

Since about 2-3 weeks I am having issues with the 2.4 GHz Wifi
It suddenly stops working… I barely notice it myself because I only use it for home automation, but iwinfo wlan1 a becomes empty (usually I have 6-10 IoT devices connected and active at any time).
using wifi wlan1 to reinitialize devices works fine for another ~24h until it breaks again…

Has anyone else had this or a similar issue?

config wifi-device 'radio1'
	option type 'mac80211'
	option country 'DE'
	option hwmode '11g'
	option path 'soc/soc:pcie-controller/pci0000:00/0000:00:03.0/0000:03:00.0'
	option disabled '0'
	option channel '11'
	option noscan '1'
	option htmode 'HT20'

config wifi-iface
	option device 'radio1'
	option network 'lan'
	option mode 'ap'
	option ssid 'XXX'
	option disabled '0'
	option encryption 'psk2'
	option key 'XXX'

You are editing config via the Luci menu, or edit the config file directly ?

config wifi-device 'radio1'
	option type 'mac80211'
	option country 'CZ'
	option hwmode '11g'
	option macaddr 'xx:xx:xx:xx:2e:4d'
	option htmode 'HT20'
	option disabled '0'
	option channel '1'
	option txpower '16'

config wifi-iface
	option device 'radio1'
	option network 'lan'
	option mode 'ap'
	option disabled '0'
	option ssid 'Buchtikovi'
	option encryption 'psk2+ccmp'
	option wpa_group_rekey '86400'
	option key 'xxxxxxxxxxxxxxxxxxxx'
	option ieee80211w '0'
	option wmm '0'

Mixed…
But it works all fine, until, at some point it stops working


#4

Did you look into system’s log whether there are entries pertinent to the drop out periods?


#5

nothing in the logs, turris-os thinks everything is fine…

So it seems to be intermittent cycle that would be rather curious by a hardware failure of the TO. Any changes in the network (living space) landscape, new neighbours or some new radio equipment in the vicinity?
