Are you following instructions or a tutorial? Are you able to link to it?

Do you have any other wireless networks configured before you did this? The error maybe implies you don’t.
If you post your /etc/config/wireless contents someone can offer additional advice to change the commands to suit your setup.
Make sure you redact any passwords.

I follow these instructions: https://openwrt.org/docs/guide-user/network/wifi/guestwifi/guest-wlan

Because I have previously created interfaces and wireless networks manually, I suspect that these standard instructions did not work for me.

But I didn't realize that there was such a config file. I cleaned it up because it contained outdated entries, although these were no longer visible in the frontend (Luci).

Now everything works!

Thanks :slight_smile:

You can ignore the "WIFI_DEV" variable and just use uci set wireless.guest.device="radio0" or uci set wireless.guest.device="radio1" in its place, depending on whether you have wifi on 2 frequencies and which one you want to use (e.g. 2.4 GHz or 5 GHz).
