Hello everyone.
I have a Linksys EA6350 v4 router on which I have installed OpenWrt 23.05.5 r24106-10cc5fcd00 (it's like the third version of OpenWRT that I've installed since I've been using it, a newer version every time it's reinstalled), there are also two Netgear WAC104 wireless access points. On all the devices I have DAWN installed and configured, the WiFi interfaces of the three devices are configured the same, with the same parameters for both WiFi and DAWN.
On the Netgear WAC104 DAWN the WiFi interfaces work well and DAWN works normally, however I have had problems with the WiFi interfaces of the Linksys EA6350 v4 router, as they stopped working. The first few times I installed OpenWRT on the Linksys EA6350 v4 router everything worked fine, however, as the Linksys EA6350 v4 router has the drawback that, if it is rebooted more than three times due to power problems, the web administration interface reverts to the original Linksys firmware, so I have to reinstall and configure OpenWRT from scratch, which has happened to me three or four times. This process has been done just as it was done the first times, as I have a text file with all the steps and configurations that are required and that worked the first times.
The last few times it has happened to me, after installing and configuring the router, the WiFi interfaces do not come up, they remain disabled.
If I scan the networks on the Linksys EA6350 v4, they find the neighboring access points, both in the 2.4GHz and 5GHz bands.
This tells me that the WiFi interfaces are not damaged and are fully functional. However, after performing the scan, they remain in the following state.
And they just don't provide service.
If I do a channel scan on the Linksys EA6350 v4 it shows me this:
Here comes the strange part, why are there two 2.4GHz network interfaces? As you can see in the images above, there is a 2.4GHz interface, radio0 and radio1, which is not true, there should be only one, radio0. And as you can see, the 2.4GHz radio1 interface does not show any channel, what I see is that there are two interfaces with the same name, radio1 2.4GHz and radio1 5GHz. I don't know if this is what causes both interfaces not to work.
The etc/config/wireless file is like this:
config wifi-device 'radio0'
option type 'mac80211'
option path '1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0'

option reassociation_deadline '1000'
option ft_over_ds '0'
option ft_psk_generate_local '1'

I don't know what else I can do or configure, it seems to be an OpenWRT problem and not a router problem.
I would greatly appreciate it if you could help me solve this problem.
