Wirelless enabled but AP does not shows up

Installing and Using OpenWrt
1

Hello.
I'm using an router with openwrt for about a year and it was last updated about 2 months ago. I use it as an Access Point and it worked well for most of the time, in the last month or so it sometimes stopped showing up on my phone and i would restart the router and the connection would be back up for a good time. As of 2 days the same thing happened and after the reboot the wifi returned, but it got back down in about a day. And now it goes downs only a few minutes after restart, i tried restarting the access points via the wireless settings on luci but it did not come back, and now the 2 ssid's appear as disabled. All of these times the wireless connections worked flawlessly. I accept any help, thanks.
The router is a TP-Link Archer C6 v3, with Firmware version: OpenWrt 23.05.2 r23630-842932a63d / LuCI openwrt-23.05 branch git-23.306.39416-c86c256.
These are the log messages when restarting the 2ghz channel:

Remove legacy rates and noscan.

Remove all of the 802.11r and change to psk2 (wpa2). Do this for all ssids defined on your device.

Remove this - it does nothing.

Reboot and test again.

This may be something else but I have seen exactly the same symptoms on numerous manufacturer's devices. In every case it was a slowly degrading/failing power supply.
The current pulses perhaps lasting a fraction of a millisecond caused when the wireless transmits become enough to lower the voltage below a threshold that causes problems. The first sign is often the ssid randomly dropping. As it gets really bad the whole device can crash or lock up.

If you have a suitable spare supply it might be worth trying it.

Removed and rebooted, unfortunately i have to keep the old encryption because of compatibility with some devices. I know it's a security risk but otherwise i would have to buy a new phone which i can't now.
The wifi is up again after a reboot, but i don't know how long it will stay up.

Will try it, the power supply is the provided with the router, probably a very cheap one. Will change it for a better one and see if it stops.

After some hours it has gone down again, just changed the power supply and rebooted.

Fingers crossed. Is the replacement power supply at least the same rating?
It is possible, depending on design, for an electrolytic smoothing capacitor inside the case of the router to be failing and give the same results. I don't know what an Archer C6 v3 has inside, but electrolytic caps usually last for at least 5 years, but who knows... How old is the router?

The same age as it's openwrt installation, about a year. I changed the power supply for a higher current one and it seens to be working, wifi did not stop until now. Do i mark the post as solved?

It helps a lot when threads are closed and the proper reply is marked as solving it.

it helps people looking through threads matching their search and, quickly, identify what has worked before.
