Fixing dropped connections on a Realtek RTL8852AE card on Windows

I recently bought a new laptop, which came with a Realtek RTL8852AE wireless card. Almost immediately, I noticed that when the laptop was on battery power, it would drop the wireless connection. When this happened, it would be impossible to re-enable the wireless connection without rebooting. Disabling and enabling wifi wouldn't fix it and running the Windows network troubleshooter would make the laptop blue screen. When I looked up the issue online, all the advice seemed to be that the card was fundamentally flawed and the only remedy was to replace it with an Intel wireless card. However, I have found a workaround that allows the card to be used without going through this hassle.

The fix

  1. Open Device Manager
  2. Find the card under "Network adapters", right click it and click "Properties"
  3. Click the "Advanced" tab. Change the "Leisure Power Save" setting from "Auto" or "High" to "Low".
  4. Click "OK".

If this didn't fix the problem, please do not contact me because I will unable to offer any additional advice.
