Run the Built-in Network Troubleshooter

Surprisingly, Microsoft’s own troubleshooter actually works for 24H2 Wi-Fi issues [4].

Step A: Press Win + I (Settings)
Step B: Navigate to System → Troubleshoot → Other troubleshooters
Step C: Click "Run" next to "Internet Connections"
Step D: Click "Run" next to "Network Adapter" and select Wi-Fi
Step E: Follow the on-screen prompts

Flush DNS & Reset IP Stack — Most Effective

This is the #1 fix for “connected but no internet” issues according to Microsoft engineers [3].

Open Command Prompt or PowerShell as Administrator:

# Step 1: Flush DNS cache
ipconfig /flushdns

# Step 2: Release current IP address
ipconfig /release

# Step 3: Renew IP address
ipconfig /renew

# Step 4: Reset Winsock catalog
netsh winsock reset

# Step 5: Reset TCP/IP stack
netsh int ip reset

# Step 6: Reset Windows Firewall (optional)
netsh advfirewall reset

After these commands, restart your PC completely.

Disable IPv6 (Temporary Fix for 24H2)

Windows 11 24H2 has a known IPv6 conflict with many routers, causing DNS failures [5].

Step A: Press Win + R → type "ncpa.cpl" → Enter
Step B: Right-click your Wi-Fi adapter → Properties
Step C: Scroll to "Internet Protocol Version 6 (TCP/IPv6)"
Step D: UNCHECK the box → Click OK
Step E: Restart your PC

✅ If this fixes the problem, keep IPv6 disabled until Microsoft releases a patch.
⚠️ Re-enable it after future Windows updates to check if the bug is resolved.

Remove WinHTTPAutoProxySvc Dependency — Advanced PowerShell Fix

This is the unique solution most other guides miss. According to PowerShell expert Harm Veenstra, the 24H2 Wi-Fi issue stems from a corrupted dependency chain where WinHTTPAutoProxySvc prevents the Windows Connection Manager from starting properly [2].

# Open PowerShell as Administrator

# Step 1: Check the current dependency
Get-Service Wcmsvc | Select-Object -ExpandProperty ServicesDependedOn

# Step 2: Remove the problematic dependency
sc config Wcmsvc depend= /"NSI"/"RpcSs"/"Dhcp"

# Step 3: Verify the fix worked
Get-Service Wcmsvc | Select-Object -ExpandProperty ServicesDependedOn

# Step 4: Restart the Windows Connection Manager
Restart-Service Wcmsvc -Force

Disable Fast Startup — Caches Broken Network States

Fast Startup saves system state (including broken network configurations) between shutdowns. Disabling it forces a clean start every time [4].

Step A: Control Panel → Power Options
Step B: Click "Choose what the power buttons do" (left sidebar)
Step C: Click "Change settings that are currently unavailable"
Step D: UNCHECK "Turn on fast startup (recommended)"
Step E: Click "Save changes" → Shutdown → Restart

Change DNS Server to Google or Cloudflare

Your ISP’s DNS servers may be failing after the 24H2 update. Switching to Google’s or Cloudflare’s public DNS fixes this [3].

Step A: Press Win + R → type "ncpa.cpl" → Enter
Step B: Right-click your Wi-Fi adapter → Properties
Step C: Double-click "Internet Protocol Version 4 (TCP/IPv4)"
Step D: Select "Use the following DNS server addresses"
Step E: Enter:
     Preferred DNS server: 8.8.8.8 (Google)
     Alternate DNS server: 8.8.4.4 (Google)
     
     OR using Cloudflare:
     Preferred DNS server: 1.1.1.1
     Alternate DNS server: 1.0.0.1
     
Step F: Click OK → Close → Restart your PC

Update or Reinstall Network Adapter Driver (Clean Install)

Corrupted drivers after the 24H2 update are a common cause. A clean installation removes all traces of the old driver [1].

Step A: Press Win + X → Device Manager
Step B: Expand "Network adapters"
Step C: Right-click your Wi-Fi adapter → Uninstall device
Step D: ✅ CHECK "Delete the driver software for this device"
Step E: Click Uninstall → Restart your PC
Step F: Windows will automatically reinstall the driver

Network Reset (Last Resort Before Reinstall)

This removes and reinstalls all network adapters and resets networking components to their original settings [6].

Step A: Press Win + I → Network & internet
Step B: Click "Advanced network settings"
Step C: Click "Network reset"
Step D: Click "Reset now" → Yes
Step E: Your PC will restart in 5 minutes

Power Cycle (Not Just Restart)

A full power drain resets the network chip’s firmware, unlike a normal Windows restart [4].

Laptop with non-removable battery / Desktop:
1. Shut down completely
2. Unplug the power cord
3. Hold the Power button for 20-30 seconds
4. Reconnect power
5. Boot normally

Laptop with removable battery:
1. Shut down and unplug power
2. Remove the battery
3. Press and hold Power button for 20 seconds
4. Reinsert battery, plug in, and turn on

Reset TCP/IP Stack via Command Line

A more aggressive version of the network reset using Command Line [3].

Open Command Prompt or PowerShell as Administrator:

# Reset TCP/IP stack to original state
netsh int ip reset C:\resetlog.txt

# Reset Winsock catalog
netsh winsock reset

# Clear DNS cache again
ipconfig /flushdns

# Renew IP address
ipconfig /renew

# Restart your PC

Registry Fix (For IT Admins / Advanced Users)

For enterprise environments and persistent cases, this registry modification can resolve DHCP failures [2].

Open Registry Editor (regedit) as Administrator:

Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WcmSvc

Check the "DependOnService" value:
- If it shows "WinHTTPAutoProxySvc," remove it
- Keep only: NSI, RpcSs, Dhcp

To fix via PowerShell:
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\WcmSvc" -Name "DependOnService" -Value @("NSI","RpcSs","Dhcp") -Type MultiString

Restart your PC.
