Wifi keeps disconnecting

Hello, I would like some help. I can provide any outputs for clarification.

I’m on KDE Neon on an older laptop, and I keep getting the Authorization supplicant disconnected after connecting to the wifi network for a few seconds. It will disconnect and reconnect in a loop, and all the networks will vanish and reappear on the list.

I can still connect wia USB tethering. I have tried downgrading the kernel multiple times, disabling power saving through a .conf file in the conf.d folder, using iwd, and disabling kde wallet.

This issue was present even in the USB live environment, but it was not present on mint running KDE 5.27 nor Kubuntu. I don’t know what to do anymore.
