How to Fix Windows 11 Wi‑Fi Keeps Disconnecting (2026 Guide)

If your Windows 11 Wi‑Fi drops every few minutes, it’s usually a driver, power setting, or router/DNS issue. Follow these fixes in order.

1) Quick checks

• Restart your router/modem and PC
• Forget the network and reconnect
• Run Windows Update

2) Disable power saving on the Wi‑Fi adapter

1. Press Win + X → Device Manager
2. Network adapters → your Wi‑Fi card → Properties
3. Power Management → uncheck “Allow the computer to turn off this device”

3) Update or reinstall the Wi‑Fi driver

• Device Manager → Update driver
• If still unstable: Uninstall device → reboot → install latest from the laptop/vendor website

4) Reset network stack

Open Command Prompt (Admin) and run:

• netsh winsock reset
• netsh int ip reset

Restart your PC.

5) Switch to a stable DNS

• Cloudflare: 1.1.1.1 and 1.0.0.1

Tip: If only one device disconnects, it’s usually drivers. If all devices drop, it’s router/ISP.
