THE PROBLEM – What’s Actually Happening
Common Symptoms
- WiFi disconnects randomly
- Laptop keeps dropping internet
- “No Internet, Secured” message
- WiFi icon disappears from taskbar
- Auto reconnect… then drops again
- Happens after sleep or a system update
When It Usually Starts

Who This Guide Is For
This fix works if you’re using:
- HP, Dell, Lenovo, or ASUS laptops
- Intel or Realtek wireless adapters
- Home, office, or public WiFi
If your system matches even one of these — you’re in the right place.
WHY THIS HAPPENS (Real Technical Causes – No Myths)
Let’s cut the guesswork. These are the actual triggers:
1. Broken or Outdated WiFi Driver
After a Windows update, your existing driver can become unstable — not missing — just glitchy.
2. Aggressive Power Saving
Windows turns off your wireless adapter to “save battery” — and kills your connection in the process.
3. Network Stack Corruption
Your TCP/IP and DNS settings get scrambled during updates.
4. Router Band Switching (2.4GHz ↔ 5GHz)
Your laptop keeps jumping between bands and drops the connection mid-switch.
5. Background Network Conflicts
VPNs, virtual adapters, or old configs interfere silently.
QUICK FIX (Featured Snippet Ready)
If your WiFi keeps disconnecting on Windows 11:
- Update the wireless driver
- Turn off power saving for the WiFi adapter
- Run the network troubleshooter
- Perform a full network reset
These four steps fix the issue for most users.

It resets core services automatically.

Settings → Network & Internet → Advanced → Network reset.
This reinstalls:

Open Command Prompt as Admin:
ipconfig /flushdns
netsh int ip reset
netsh winsock reset
This clears hidden network corruption.
