Unable to set up Wifi on Raspberry Pi 4

I have a Raspberry Pi 4 with OpenWrt SNAPSHOT r17693-c2222f74c8
I want to make a dumb AP, I follow the guides out there, but the network does not show.
Appreciate if some one can help me with wifi on raspberry pi. Its not working.
Here are my settings:
etc/config/wireless

        option type 'mac80211'
        option path 'platform/soc/fe300000.mmcnr/mmc_host/mmc1/mmc1:0001/mmc1:0001:1'
        option band '5g'
        option htmode 'VHT80'
        option cell_density '0'
        option channel '36'
        option country 'ES'

config wifi-iface 'wifinet0'
        option device 'radio0'
        option mode 'ap'
        option ssid 'OpenWrt'
        option encryption 'psk2'
        option key '***'
        option network 'lan'

etc/config/network

config interface 'loopback'
        option device 'lo'
        option proto 'static'

        option ula_prefix 'fdb3:51c0:4d85::/48'

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'eth0'

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option ipaddr '192.168.1.172'
        option gateway '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

Does your client support the channel specified?

mk24 · October 12, 2021, 4:13pm

Is that the whole /etc/config/wireless file? The first block needs to be under a header of config wifi-device 'radio0'.

Try channel 149 instead of 36 as the group 3 channels have unrestricted use in Spain.

fwiw, I presume the actual wifi password is at least 8 characters long ?

galxy_star · October 12, 2021, 5:32pm

yes , is longer than 8 characters

galxy_star · October 12, 2021, 5:37pm

I forgot to paste the header block in the forum but I have it in the configuration, same happens with channel 149

I want to conect a wireless pc and and my iphone

Open a ssh session and run logread -f to watch the log. Then in another terminal attempt to (re)start wifi by running the command wifi or on the gui disable and re-enable wifi. Post the log entries. If there's no error you should see AP-ENABLED as one of the messages.

If I restart the RPI
but the Ap doesnt show

Try option htmode ‘HT20’ or ‘HT40’, VHT80 seems to be very finicky on the pi4.

galxy_star · October 12, 2021, 6:28pm

Thanks a lot!! It worked with htmode 'HT20'
