Step 1: The Golden Rule – Restart Everything
Before you delve into complex settings, always start with the simplest yet often most effective solution: a good old-fashioned restart.
1. Restart your Windows 11 PC: Go to Start > Power > Restart.
2. Restart your Router and Modem: Unplug both your Wi-Fi router and your internet modem from their power outlets. Wait for about 30-60 seconds, then plug the modem back in first. Wait for all its indicator lights to stabilize (usually a minute or two), then plug your router back in and wait for its lights to stabilize.
* Why this works: Restarting clears temporary glitches, refreshes IP addresses, and re-establishes connections between all your network devices.

Step 2: Basic Checks & Quick Fixes
Sometimes the issue isn’t software deep but a simple oversight.
1. Check for Airplane Mode:
* Click the Network icon (Wi-Fi symbol) on your taskbar.
* Ensure Airplane mode is turned Off. If it’s on, click it to toggle it off.
* Also, ensure Wi-Fi itself is turned On.
2. Forget and Reconnect to the Network:
* Go to Settings > Network & internet > Wi-Fi.
* Click Manage known networks.
* Find your problematic network, click on it, and select Forget.
* Go back to the Wi-Fi list, find your network again, and reconnect by entering your password.
* Why this works: This forces Windows to drop any corrupted connection profiles and establish a fresh connection.
3. Check Physical Connections (for wired networks): If you’re using an Ethernet cable, ensure it’s securely plugged into both your PC and your router. Try a different cable or port if possible.
4. Try Another Device: Is the Wi-Fi issue specific to your Windows 11 PC, or are other devices (phone, tablet, other laptops) also unable to connect or experiencing problems?
If only* your PC has issues, the problem is likely with your PC.
If all* devices have issues, the problem is likely with your router, modem, or ISP.

Step 4: Driver-Related Solutions (The Most Common Culprit)
Outdated, corrupted, or incompatible Wi-Fi drivers are a frequent cause of network problems.
1. Update Your Wi-Fi Adapter Driver:
* Press `Win + X` and select Device Manager.
* Expand Network adapters.
* Right-click on your Wi-Fi adapter (it might have “Wireless,” “WLAN,” or “802.11” in its name) and select Update driver.
* Choose Search automatically for drivers. If Windows finds a newer driver, install it.
* Crucially: If Windows doesn’t find one, visit your PC manufacturer’s support website (e.g., Dell, HP, Lenovo, Microsoft Surface) or the Wi-Fi adapter manufacturer’s website (e.g., Intel, Realtek, Broadcom). Download the latest Windows 11 driver for your specific model and install it manually. Restart your PC afterward.
* Why this works: Manufacturer-specific drivers are often more stable and feature-rich than generic Windows drivers.
2. Roll Back the Wi-Fi Adapter Driver: If your Wi-Fi stopped working after a recent Windows update or driver installation, rolling back might help.
* In Device Manager, right-click your Wi-Fi adapter and select Properties.
* Go to the Driver tab and click Roll Back Driver (if available).
* Why this works: Reverts to a previously working driver version.
3. Uninstall and Reinstall the Wi-Fi Adapter Driver:
* In Device Manager, right-click your Wi-Fi adapter and select Uninstall device.
* Check the box that says “Attempt to remove the driver for this device” if available.
* Click Uninstall.
* Restart your PC. Windows 11 will usually automatically detect and reinstall the driver upon reboot. If not, manually install the driver you downloaded from the manufacturer’s website.
* Why this works: Cleans out any corrupted driver files and forces a fresh installation.
4. Disable/Enable the Wi-Fi Adapter:
* In Device Manager, right-click your Wi-Fi adapter and select Disable device.
* Wait a few seconds, then right-click it again and select Enable device.
* Why this works: Can sometimes reset the adapter and clear temporary hang-ups without a full driver reinstallation.

Step 5: Advanced Network Resets & Commands
If the basic and driver steps haven’t worked, it’s time to reset Windows’ network components.
1. Reset Network Settings: This is a more drastic step that reinstalls all network adapters and resets all network components to their default settings. You will need to re-enter your Wi-Fi passwords and reconnect to all your networks.
* Go to Settings > Network & internet > Advanced network settings.
* Click Network reset.
* Click Reset now and confirm. Your PC will restart.
* Why this works: This often fixes deep-seated configuration issues by giving Windows a clean slate for its network stack.
2. Flush DNS and Reset IP Configuration:
* Press `Win + R`, type `cmd`, and press `Ctrl + Shift + Enter` to open Command Prompt as administrator.
* Type the following commands, pressing `Enter` after each one:
* `ipconfig /release` (Releases your current IP address)
* `ipconfig /renew` (Requests a new IP address)
* `ipconfig /flushdns` (Clears cached DNS entries)
* Close Command Prompt and test your connection.
* Why this works: Clears out old, potentially conflicting IP assignments and DNS caches that can prevent internet access.
3. Reset Winsock and IP Stack:
* Open Command Prompt as administrator (as above).
* Type the following commands, pressing `Enter` after each one:
* `netsh winsock reset`
* `netsh int ip reset`
* Restart your PC after running these commands.
* Why this works: Winsock (Windows Sockets) is a programming interface for network applications. Resetting it can resolve issues where applications can’t access the network correctly. Resetting the IP stack can fix problems with the TCP/IP protocol.

Step 9: Hardware or Router-Specific Issues
If all Windows-related solutions fail, the problem might lie outside your PC.
1. Update Router Firmware: Check your router manufacturer’s website for firmware updates. Outdated router firmware can cause compatibility issues with newer devices or operating systems.
2. Change Wi-Fi Channel/Frequency: Log into your router’s admin interface. Try changing the Wi-Fi channel (especially for 2.4GHz networks) to avoid interference from neighboring networks. You might also try switching between 2.4GHz and 5GHz bands if your router supports both.
3. Contact Your ISP: If multiple devices are affected and you’ve exhausted router troubleshooting, contact your Internet Service Provider. There might be an outage or an issue with your modem or their service line.
4. Hardware Failure: In rare cases, your Wi-Fi adapter itself might be faulty. If it’s an external USB adapter, try a new one. If it’s internal, you might consider a USB Wi-Fi dongle as a temporary or permanent solution.
