Hi,
perhaps it's an easy issue, but I can't find it
device is an Lenovo Newifi Mini Y1
OpenWRT 19.07.5 is installed and running
there are 2 radios in the device
radio0 = 5 GHz
radio1 = 2.4 GHz
on both radios I have configured an 802.11s mesh with encryption, and both meshed do work (batctl shows the neighbours and the other mesh points do see this device as well)
so in principle wpa_supplicant is working.
wpad-mesh-openssl is installed
APs without encryption do work on both radios, the the wifi-device settings seem to be OK
Now for the error:
when I set up APs with encryption on the radios, this only works on the 5 GHz radio, using
option encryption 'sae-mixed'
but it does not work on 2.4 GHz (radio1)
I started with an encrypted AP and added one option after the other. Everything worked until I added
option encryption
option key
As soon as I try that, the interface does not come up anymore.
neither 'sae-mixed' nor 'psk2' work.
config wifi-device 'radio1'
option type 'mac80211'
option channel '9'
option hwmode '11g'
option path 'platform/10180000.wmac'
option htmode 'HT40'
option country 'DE'
option diversity '1'
option disabled '0'
this works fine
config wifi-iface 'default_radio1'
option device 'radio1'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt-test'
option encryption 'none'
option ieee80211w '1'
option ieee80211r '1'
option mobility_domain '6f68'
option disabled '0'
and this works fine as well, but this is on radio0 = 5 GHz
config wifi-iface 'prod_radio0'
option device 'radio0'
option mode 'ap'
option ssid 'Test'
option key '1111111111111111'
option network 'lan'
option ieee80211w '1'
option encryption 'sae-mixed'
option ieee80211r '1'
option mobility_domain '6f68'
option disabled '0'
and this does NOT work (radio1 = 2.4 GHz)
config wifi-iface 'prod_radio1'
option device 'radio1'
option mode 'ap'
option ssid 'Tst'
option key '1111111111111111'
option network 'lan'
option ieee80211w '1'
option encryption 'sae-mixed'
# option encryption 'psk2+tkip+aes'
option ieee80211r '1'
option mobility_domain '6f68'
option disabled '0'
the config for prod_radio1 has been copy&paste form prod_radio0 in nano and just changing the 0's to 1's ...
I have totally run out of ideas
