My Spectrum sax1v1k is working just fine with 24.10.4 but after upgrading to any version starting with 24.10.5 including the latest 25.12-rc4 I can’t scan any 2.4GHz wifi and this is critical as my device is a wireless extender - I’ve tried with default config:
root@sax1v1k-WAP:~# cat /etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option path 'platform/soc@0/c000000.wifi'
option band '5g'
option channel '36'
option htmode 'HE80'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'open'
config wifi-device 'radio1'
option type 'mac80211'
option path 'platform/soc@0/c000000.wifi+1'
option band '2g'
option channel '1'
option htmode 'HE20'
config wifi-iface 'default_radio1'
option device 'radio1'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'open'
and logs after enabling this config:
