Wifi is lost on battery power after 30% has been consumed

[palmaxzero]

I have noticed that whenever I am on battery power and I have used around 30% of my battery: for example, starting from 100% charge, if battery drops to 70%,

my pc automatically disconnects from the connected wifi. Not even that, it is unable to find any more wifi networks. I tried disabling and reenabling wifi, wifi adapter, switching to high performance mode, turning off power saving for wifi adapter, but nothing works. The only way I can reconnect is to restart the PC. Then it works again for the next 30%. I believe this is a problem with realtek adapters on windows 11, because it works flawlessly on my other system with intel adapter or on this system, when using linux.

Here's why 5G Wireless mode from driver properties for reference.

Any solution is much appreciated because I am not interested in keeping my laptop always connected to a wall charger or in high-performance mode forever.

I think you misunderstand me. My problem is not my battery, but my Wifi. My Wifi disconnects randomly, when on battery power.

For example, it is perfectly fine right now. But when my battery reaches around 60%, it will disconnect
