Enabling radio1 on boot (BCM2711/Raspberry Pi 4)

I've successfully got OpenWrt running on my Raspberry Pi 4 and my intentions is to turn it into a travel router. How can I automatically enable radio1 to turn on during boot? Ideally, it's a plug-and-play, if possible.

Using Fenvi FU-AX1800 (mt7921u) for my USB WiFi adapter.

Do you see the device in Network/Interfaces/Devices?

Yes. Is there a setting that I missed and need to configure in there to make it work? Thanks!

Well, that is good news.
It should, also, be showing up in Network/Wireless and it may just need to be enabled but that is not going to be the ideal setup.

What instructions (i.e. who's tutorial) did you use?

Before we start chasing rabbits through a warren, you need to do some things to help us help you:
Did you ensure the Pi has the latest bootloader installed? If not, please follow all these instructions:

Then show us what is configured using ssh.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button by highlighting the paste then clicking this:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Just for academics: you can run OpwnWrt on a pi zero w or pi zero 2 if this is truly just a travel router...

But, regardless, we need to get on the same page first.
