Ultimate Guide to Fixing Windows 11 Network Problems 2026
Windows 11 runs on more than 400 million active devices worldwide based on recent industry estimates. A large percentage of support requests relate to network issues. Slow internet, WiFi disconnects, Ethernet errors, and DNS failures affect daily work, streaming, and online meetings.
This guide gives you direct and practical steps to fix Windows 11 network problems. Follow the sections that match your issue. Apply each step in order. Test your connection after each fix.
Common Windows 11 Network Problems
You may face one or more of these issues:
• WiFi connected but no internet access
• No Internet, Secured error
• Ethernet not working
• DNS_PROBE_FINISHED_NO_INTERNET
• Slow download speeds
• Frequent WiFi disconnections
• Bluetooth network interference
• Limited access or unidentified network
Microsoft support data shows that driver issues and router misconfiguration cause a large share of home network problems. Software updates also trigger temporary connectivity errors.
Step 1. Restart Your Network Devices
Restarting fixes many network errors.
Do this first:
1. Turn off your PC.
2. Unplug your router and modem from power.
3. Wait 60 seconds.
4. Plug in the modem and wait until all lights stabilize.
5. Plug in the router.
6. Turn on your PC.
This resets the connection between your device and your internet service provider. Many temporary IP conflicts disappear after this step.
Step 2. Check Physical Connections
If you use Ethernet, inspect the cable.
• Ensure the cable clicks firmly into the port.
• Try a different Ethernet cable.
• Test another router port.
If you use WiFi, move closer to the router. Thick walls and metal surfaces reduce signal strength. A weak signal causes unstable internet.
Open Settings.
Go to Network and Internet.
Check connection status.
If Windows shows No internet, continue to the next steps.
Step 3. Run Windows Network Troubleshooter
Windows 11 includes a built in troubleshooter.
Open Settings.
Click System.
Select Troubleshoot.
Click Other troubleshooters.
Run Internet Connections.
The tool checks adapter configuration, gateway access, and DNS response. It often fixes IP conflicts automatically.
Step 4. Reset Network Adapter
Network adapters sometimes stop responding after updates.
Press Windows plus X.
Select Device Manager.
Expand Network adapters.
Right click your WiFi or Ethernet adapter.
Click Disable.
Wait 10 seconds.
Click Enable.
This refreshes the driver without a full reinstall.
Step 5. Update Network Drivers
Outdated drivers cause connection drops and slow speeds.
Open Device Manager.
Right click your network adapter.
Select Update driver.
Choose Search automatically for drivers.
You can also download drivers from your laptop manufacturer website. Updated drivers improve compatibility with Windows 11 updates.
Intel reports that driver updates improve WiFi stability and throughput on supported chipsets. Keeping drivers current reduces packet loss.
Step 6. Reset TCP IP and Flush DNS
Corrupted network settings block internet access.
Open Command Prompt as administrator.
Type the following commands one by one and press Enter after each:
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Restart your computer.
This process resets your IP configuration and clears DNS cache. It fixes many DNS_PROBE errors.
Step 7. Fix No Internet Secured Error
If Windows shows No Internet, Secured, your device connects to the router but fails to reach the internet.
Follow these steps:
• Restart router and PC.
• Update network drivers.
• Disable VPN temporarily.
• Forget WiFi network and reconnect.
To forget a network:
Open Settings.
Go to Network and Internet.
Click WiFi.
Select Manage known networks.
Choose your network.
Click Forget.
Reconnect by entering the password.
Step 8. Set DNS Manually
Your ISP DNS server may respond slowly.
Change DNS settings:
Open Control Panel.
Click Network and Internet.
Select Network and Sharing Center.
Click Change adapter settings.
Right click your connection.
Select Properties.
Click Internet Protocol Version 4.
Click Properties.
Select Use the following DNS server addresses.
Enter:
Preferred DNS server 8.8.8.8
Alternate DNS server 8.8.4.4
Save changes and restart your browser.
Public DNS servers often respond faster and resolve domain errors.
Step 9. Reset Network Completely
If problems persist, reset the entire network configuration.
Open Settings.
Go to Network and Internet.
Click Advanced network settings.
Select Network reset.
Click Reset now.
Windows removes all network adapters and reinstalls them. You will need to reconnect to WiFi afterward.
This step fixes deep configuration conflicts.
Step 10. Fix Slow Internet Speeds
If your connection works but feels slow, test your speed using an online speed test.
Compare the result with your internet plan. If you pay for 100 Mbps and receive 15 Mbps, identify the cause.
Common reasons:
• Background downloads
• Windows updates
• Weak WiFi signal
• Router congestion
• Old router hardware
Improve speed with these actions:
• Move closer to router.
• Use Ethernet instead of WiFi.
• Restart router weekly.
• Limit background apps.
Open Task Manager.
Click Processes.
Check network usage column.
Disable unnecessary apps that consume bandwidth.
Step 11. Check Windows Update Issues
Some Windows updates affect network drivers.
Open Settings.
Go to Windows Update.
Click Update history.
If network problems started after an update, uninstall the recent update.
Click Uninstall updates.
Select the latest update.
Click Uninstall.
Restart your PC and test connection.
Step 12. Disable Power Saving for Network Adapter
Windows sometimes turns off adapters to save power.
Open Device Manager.
Right click network adapter.
Select Properties.
Go to Power Management tab.
Uncheck Allow the computer to turn off this device to save power.
Click OK.
This reduces random disconnections.
Step 13. Fix Ethernet Not Working
If Ethernet shows Unidentified network:
• Try a different cable.
• Test another device on the same cable.
• Reset TCP IP.
• Update Ethernet driver.
If another device connects successfully, focus on your PC configuration.
Step 14. Check Router Settings
Log into your router using its IP address, often 192.168.1.1 or 192.168.0.1.
Check:
• Firmware updates
• DHCP enabled
• No MAC filtering blocking your device
• No bandwidth limits
Router firmware updates fix stability issues and security flaws. Many manufacturers release updates several times per year.
Step 15. Fix Frequent WiFi Disconnects
Frequent drops usually relate to interference or driver issues.
Change WiFi channel inside router settings.
Use 5 GHz band if supported.
Update WiFi driver.
Disable Bluetooth temporarily to test interference.
Place router in a central location away from metal objects and microwaves.
Step 16. Scan for Malware
Malware affects network traffic and DNS settings.
Open Windows Security.
Click Virus and threat protection.
Run a full scan.
Remove any detected threats. Restart your PC.
Step 17. Check Firewall and Antivirus Settings
Third party security software sometimes blocks internet access.
Temporarily disable firewall in your antivirus program.
Test connection.
If internet works, adjust firewall rules instead of keeping it disabled.
Step 18. Contact Your Internet Service Provider
If none of the above steps restore internet, contact your ISP.
Provide:
• Your speed test result
• Time of issue
• Router model
• Error message displayed
ISPs check line stability and signal strength remotely. They confirm outages in your area.
Prevent Future Network Problems
Follow these habits to reduce future issues:
• Restart router once per week.
• Keep Windows updated.
• Update network drivers regularly.
• Use strong WiFi password.
• Place router in open space.
• Replace router every five to seven years.
Modern routers support higher speeds and better stability.
Quick Reference Checklist
If your Windows 11 internet stops working, follow this order:
• Restart router and PC
• Run troubleshooter
• Reset adapter
• Update drivers
• Flush DNS
• Set manual DNS
• Reset network
• Check router firmware
Applying these steps resolves most Windows 11 network problems reported by home users.
This guide gives you a structured process. Move step by step. Test after each fix. Focus on configuration, drivers, and router health. Stable internet depends on all three.
