Resolving Windows 11 Wi-Fi Connectivity Issues Through Network Reset

Experiencing Wi-Fi or internet connectivity problems on your Windows 11 PC? Resetting your network settings can often resolve these issues. This guide details the process and what to expect.

Understanding Network Reset

A network reset in Windows 11 reinstalls all network adapters (Wi-Fi, Ethernet, VPN), removes saved Wi-Fi networks, and clears custom DNS, proxy, and IP configurations. If you have many saved networks, consider exporting them beforehand (instructions below).

When to Reset Network Settings

A network reset is beneficial for various network problems, including:

• Difficulty connecting to the internet.
• Frequent Wi-Fi disconnections.
• Interference from VPN or proxy settings.
• Switching networks and needing a fresh start.

Performing a Network Reset

1. Open Windows Settings (Windows key + I).
2. Navigate to "Network & Internet" then "Advanced network settings".
3. Select "Network reset" under "More settings".
4. Click "Reset now" and confirm when prompted. Windows will then reset your network configuration.

Post-Reset Steps

After the reset, reconnect to your Wi-Fi networks, re-enter passwords, and reinstall any VPNs. Re-enter any static IP addresses or custom DNS settings if previously used.

Exporting Saved Wi-Fi Networks

To avoid re-entering Wi-Fi passwords after a reset, export your saved networks:

1. Create a folder (e.g., "C:\WiFiBackup").
2. Open Command Prompt (search for "cmd" and run as administrator).
3. Execute this command: netsh wlan export profile folder="C:\WiFiBackup" key=clear
4. XML files containing your network profiles (including passwords) will be created in the folder.

To import these profiles later:

1. Open Command Prompt (as administrator).
2. Run this command: for %f in ("C:\WiFiBackup*.xml") do netsh wlan add profile filename="%f"

Troubleshooting Persistent Issues

If problems persist after a reset, consider these possibilities:

• Faulty hardware: Check your network adapter.
• ISP issues: Contact your internet service provider.
• Malware/firewall: Run a malware scan and review firewall settings.
• Network problem: Test with another device to isolate the issue (PC or network). Consult a network technician if necessary.

If the network reset doesn't solve the problem, a factory reset of your Windows 11 PC may be the next step.
