There are few things more frustrating than working, watching a video, playing a game, or browsing the web when your Windows 11 computer suddenly loses its internet connection.
The Wi-Fi icon may show that you’re disconnected, websites may stop loading, or the connection may disappear for a few seconds and then come back automatically.
Sometimes the problem is caused by your computer. In other cases, the issue may be related to your Wi-Fi router, network adapter, driver, ISP, DNS, signal strength, or Windows network settings.
The good news is that random internet disconnections can often be fixed without reinstalling Windows.
In this guide, we’ll look at the most common reasons why Windows 11 disconnects from the internet randomly and show you how to troubleshoot each one step by step.
Why Does Windows 11 Keep Disconnecting From the Internet?
Random internet disconnections can have many different causes.
Before changing anything, it’s important to determine whether the problem is with Windows 11 itself or the internet connection as a whole.
Common causes include:
- Weak Wi-Fi signal
- Router problems
- ISP outages
- Outdated network drivers
- Wi-Fi power-saving settings
- Windows network configuration problems
- DNS problems
- Network adapter issues
- VPN interference
- Wi-Fi interference
- DHCP or IP address problems
- Faulty cables
- Overheating networking equipment
First Check Whether Other Devices Disconnect
This is one of the most useful tests.
When your Windows 11 PC loses internet access, check your phone or another device connected to the same router.
If all devices lose internet access, the problem is probably related to your router, modem, ISP or wider network.
If only your Windows 11 PC disconnects, the problem is more likely related to Windows, your network adapter, drivers or the PC’s configuration.
Fix 1: Restart Your Router
Before making complicated changes to Windows, restart your router.
How to Restart Your Router
Turn off your router.
Wait for around 30 seconds.
Turn the router back on.
Wait until the internet connection becomes available again.
Then reconnect your Windows 11 computer.
Why Can This Help?
Routers can occasionally develop temporary problems involving:
- DHCP
- DNS
- Memory
- Wi-Fi services
- Network connections
- ISP authentication
A restart can clear temporary problems and establish a fresh connection.
If your internet keeps disconnecting again after a short period, continue with the troubleshooting steps below.
Fix 2: Check Your Wi-Fi Signal Strength
If you’re using Wi-Fi, a weak signal can cause intermittent disconnections.
Walls, floors, furniture and other wireless devices can affect the signal between your PC and router.
Check Your Connection
Click the Wi-Fi icon on the Windows 11 taskbar.
Look at the Wi-Fi signal strength.
If the signal is very weak, try moving closer to the router.
You can also test the connection from another location.
Improve Wi-Fi Signal
Try:
- Moving the router to a more central location
- Moving your PC closer to the router
- Removing large obstacles around the router
- Keeping the router away from certain electronic devices
- Using the 5 GHz or 6 GHz band when appropriate
- Using 2.4 GHz when longer range is more important
If the connection becomes stable when you’re closer to the router, signal strength or wireless interference may be the main problem.
Fix 3: Forget and Reconnect to the Wi-Fi Network
Sometimes the saved Wi-Fi configuration in Windows can become problematic.
Removing the network and reconnecting can create a fresh connection profile.
How to Forget a Wi-Fi Network
Open:
Settings → Network & Internet → Wi-Fi → Manage known networks
Find your Wi-Fi network.
Click:
Forget
Then return to the Wi-Fi menu and connect to the network again.
Enter your Wi-Fi password when prompted.
Why Can This Work?
Windows stores information about wireless networks.
If that stored configuration becomes corrupted or conflicts with a changed router configuration, forgetting and reconnecting can sometimes resolve the problem.
Fix 4: Restart Your Network Adapter
Your Wi-Fi or Ethernet adapter may occasionally stop working correctly.
Disabling and re-enabling it can refresh the connection.
How to Restart the Adapter
Go to:
Settings → Network & Internet → Advanced network settings
Find your network adapter.
Click:
Disable
Wait a few seconds.
Then click:
Enable
Try browsing the internet again.
Fix 5: Update Your Network Driver
An outdated, incompatible or corrupted network driver can cause random disconnections.
This is particularly worth checking if the problem started after a Windows update, driver update, or hardware change.
How to Update Your Driver
Right-click the Start button.
Select:
Device Manager
Expand:
Network adapters
Find your Wi-Fi or Ethernet adapter.
Right-click it and select:
Update driver
Then follow the instructions provided by Windows.
Download Drivers From the Manufacturer
If Windows doesn’t find a suitable driver, check the official website of your:
- Laptop manufacturer
- Motherboard manufacturer
- Wi-Fi adapter manufacturer
- Ethernet adapter manufacturer
For the best compatibility, use a driver intended specifically for your hardware and Windows version.
Fix 6: Disable Wi-Fi Power Saving
Windows may use power-management features that can affect a wireless adapter.
This is particularly worth checking on laptops.
How to Check Power Management
Open:
Device Manager
Expand:
Network adapters
Right-click your Wi-Fi adapter.
Select:
Properties
Open the:
Power Management
tab.
If you see:
Allow the computer to turn off this device to save power
you can test whether disabling this option improves connection stability.
Uncheck the option and click OK.
When Is This Useful?
If your Wi-Fi disconnects:
- After the computer becomes idle
- When waking from sleep
- When running on battery
- At seemingly random intervals
power-management settings are worth investigating.
Fix 7: Change Wi-Fi Power Settings
Windows power settings can influence how networking hardware operates.
Check Your Power Mode
Go to:
Settings → System → Power & battery
Look at your current power mode.
If you’re troubleshooting a laptop, temporarily testing a less aggressive power-saving configuration can help determine whether power management is involved.
If the problem disappears, you can adjust the settings further to find a balance between battery life and connection stability.
Fix 8: Flush the DNS Cache
DNS problems don’t normally cause the physical Wi-Fi connection to disappear, but they can make it appear as though the internet has stopped working because websites cannot be resolved.
How to Flush DNS
Open Command Prompt.
Run:
ipconfig /flushdns
Press Enter.
Windows should confirm that the DNS Resolver Cache has been flushed.
Then test your internet connection again.
Fix 9: Renew Your IP Address
Your computer receives an IP address from your router or another DHCP server.
Problems with DHCP or IP configuration can sometimes cause connectivity issues.
Release the Current IP Address
Open Command Prompt as administrator.
Run:
ipconfig /release
Your network connection may temporarily disappear.
Request a New IP Address
Then run:
ipconfig /renew
Windows will request a new IP address.
Try using the internet again.
Fix 10: Reset Winsock
Windows uses Winsock to handle network communication between applications and the network stack.
If its configuration becomes corrupted, resetting it can help with certain connectivity problems.
Reset Winsock
Open Command Prompt as administrator.
Run:
netsh winsock reset
Then restart your computer.
After Windows starts again, check whether the random disconnections continue.
Fix 11: Reset TCP/IP
Problems with the Windows TCP/IP configuration can also cause network connectivity issues.
Reset TCP/IP
Open Command Prompt as administrator.
Run:
netsh int ip reset
Restart your computer afterward.
This resets parts of the Windows IP networking configuration.
Fix 12: Check Your DNS Server
If your computer stays connected to Wi-Fi but websites randomly stop loading, your DNS server could be involved.
Test DNS
Open Command Prompt and run:
nslookup google.com
If the lookup fails repeatedly, your DNS configuration may need attention.
You can also test another DNS server directly.
For Cloudflare:
nslookup google.com 1.1.1.1
For Google:
nslookup google.com 8.8.8.8
If another DNS resolver works consistently while your normal resolver doesn’t, DNS may be contributing to the problem.
Fix 13: Try a Different DNS Server
If your ISP’s DNS server is unreliable, changing DNS may improve reliability.
Popular DNS Options
Cloudflare DNS
1.1.1.1
1.0.0.1
Google Public DNS
8.8.8.8
8.8.4.4
Quad9
9.9.9.9
149.112.112.112
You can change DNS through:
Settings → Network & Internet → Wi-Fi/Ethernet → DNS server assignment → Edit
Then select Manual and enter your chosen DNS servers.
Fix 14: Check Whether Your VPN Is Causing the Problem
VPN applications can modify network routing and DNS settings.
If your internet connection becomes unstable only when a VPN is enabled, the VPN may be contributing to the problem.
Test Your Connection Without the VPN
Temporarily disconnect your VPN.
Use the internet normally for a while.
If the disconnections stop, check your VPN application’s settings or try another VPN server.
You can also update the VPN application to its latest version.
Don’t permanently disable your VPN if you rely on it for privacy or security; this is simply a troubleshooting test.
Fix 15: Check for Wi-Fi Interference
Wireless interference can cause unstable connections, especially in areas with many nearby Wi-Fi networks.
Common Sources of Interference
Possible sources include:
- Nearby Wi-Fi routers
- Bluetooth devices
- Wireless peripherals
- Certain household electronics
- Physical obstacles
- Congested Wi-Fi channels
If many networks are operating close to each other, your router may experience interference.
Try Another Wi-Fi Band
If your router supports multiple bands, test:
2.4 GHz
5 GHz
or, where supported:
6 GHz
2.4 GHz generally provides better range, while higher-frequency bands can offer higher performance at shorter distances.
Fix 16: Restart Windows Network Services
Windows relies on multiple services for networking.
If a network-related service becomes stuck, restarting the computer often resolves it.
Restart Windows
If the problem occurs repeatedly, perform a normal Windows restart.
This can reload:
- Network drivers
- Network services
- TCP/IP components
- Wireless services
- DHCP components
If restarting temporarily fixes the problem but it returns frequently, continue investigating the underlying cause.
Fix 17: Check Your Ethernet Cable
If you’re using Ethernet rather than Wi-Fi, don’t overlook the physical connection.
A damaged or loose cable can cause intermittent disconnections.
Try Another Cable
Disconnect the Ethernet cable.
Inspect the connectors.
Reconnect it securely.
If possible, test with another Ethernet cable.
Also try another Ethernet port on the router.
If the problem disappears, the cable or router port may have been responsible.
Fix 18: Check Your Router Firmware
Your router’s software may contain bugs or compatibility issues.
Check for Router Updates
Log in to your router’s administration interface.
Look for a section such as:
Firmware Update
or:
System Update
If a newer official firmware version is available, follow the manufacturer’s instructions to update the router.
Avoid interrupting the router during a firmware update.
Fix 19: Check Windows Update
Microsoft regularly releases updates that can include networking fixes, driver changes and security improvements.
Check for Updates
Go to:
Settings → Windows Update
Click:
Check for updates
Install applicable updates and restart the computer if Windows asks you to.
What If the Problem Started After an Update?
If the random disconnections began immediately after a Windows or driver update, the update could be relevant.
In that situation, check whether your PC manufacturer’s website has a newer network driver designed for the current Windows version.
If the problem is widespread, Microsoft may also release a subsequent update containing a fix.
Fix 20: Run Windows Network Troubleshooting
Windows 11 includes troubleshooting features that can help identify network problems.
Run the Built-In Troubleshooter
Open:
Settings → System → Troubleshoot → Other troubleshooters
Look for the available network-related troubleshooting options.
Follow the instructions and allow Windows to check the connection.
The exact troubleshooting options can vary depending on your Windows 11 version and configuration.
Fix 21: Use Windows Network Reset
If you’ve tried everything else and Windows networking still behaves strangely, you can use Network reset.
How to Reset Network Settings
Go to:
Settings → Network & Internet → Advanced network settings → Network reset
Select:
Reset now
Windows will reinstall network adapters and reset network-related settings.
After the computer restarts, you’ll need to reconnect to your Wi-Fi network.
When Should You Use Network Reset?
Use this as a later troubleshooting step rather than the first thing you try.
That’s because it can remove network-related configurations and may require you to set up your connections again.
How to Find Out What Is Actually Causing the Problem
Instead of trying random fixes, you can perform a few simple tests.
Test 1: Check Other Devices
When Windows disconnects, check your phone or another device.
Other devices also disconnect → Router/ISP/network issue is more likely.
Only Windows disconnects → Windows/adapter/driver issue is more likely.
Test 2: Check Wi-Fi vs Internet
Look at the Wi-Fi icon.
If Windows remains connected to the router but websites don’t load, investigate DNS, IP configuration and the wider internet connection.
If the Wi-Fi connection itself disappears, investigate:
- Wi-Fi signal
- Driver
- Adapter
- Power management
- Router
- Wireless interference
Test 3: Use Ping
Open Command Prompt and run:
ping 1.1.1.1 -t
Let it run for a while.
If you see repeated successful replies, your computer can reach that IP address.
If you see:
Request timed out.
during the disconnection, the problem may involve the network connection rather than DNS alone.
Press:
Ctrl + C
to stop the test.
A Useful Test: Ping Your Router
You can also test the connection between your PC and router.
Find Your Default Gateway
Run:
ipconfig
Look for:
Default Gateway
It may look similar to:
192.168.1.1
Then run:
ping 192.168.1.1 -t
Use the actual gateway address shown on your computer.
How to Interpret the Result
If your router responds consistently but 1.1.1.1 stops responding, the problem may be beyond your local network.
If your router itself stops responding, investigate:
- Wi-Fi signal
- Network adapter
- Router
- Ethernet cable
- Local network configuration
This simple test can help narrow down where the problem is happening.
What If Only One Website Disconnects?
If one website stops working while other websites continue working, your internet connection may be fine.
The problem could be related to:
- The website’s server
- DNS records
- CDN
- Your browser
- The website itself
- Regional routing
Test Another Website
Try several unrelated websites.
If they all work except one, don’t immediately change your Windows network configuration.
The problem may not be on your computer.
What If Wi-Fi Disconnects Every Few Minutes?
Frequent disconnections every few minutes can point toward a specific set of problems.
Things to Check
Start with:
1. Wi-Fi signal strength
2. Power management
3. Network driver
4. Router
5. Wi-Fi interference
6. Windows network settings
7. VPN
8. Hardware
If the same computer disconnects on multiple different Wi-Fi networks, the computer’s Wi-Fi adapter or Windows configuration becomes more suspicious.
If it disconnects only on one particular router, the router or its configuration may be responsible.
What If Ethernet Also Disconnects?
If both Wi-Fi and Ethernet randomly lose internet access on the same Windows 11 PC, the problem may be broader than a single wireless adapter.
Check These Areas
Look at:
- Router
- ISP
- Windows networking
- DNS
- TCP/IP
- VPN
- Security software
- Windows updates
If another device connected to the same router experiences the same issue, focus on the router or ISP first.
When Should You Contact Your ISP?
Sometimes the problem has nothing to do with Windows 11.
Contact Your ISP If:
- Multiple devices lose internet access
- Wi-Fi and Ethernet both stop working
- The router repeatedly loses its internet connection
- Your connection drops at specific times
- Your ISP’s DNS repeatedly fails
- The modem/router shows an internet or WAN error
- The problem continues after testing different devices
Your ISP can check whether there is an outage or an issue with your connection.
When Could It Be a Hardware Problem?
If you’ve tried different networks and Windows continues disconnecting, the network adapter itself could be having a problem.
Possible Hardware Issues
These can include:
- Failing Wi-Fi adapter
- Faulty Ethernet port
- Damaged Ethernet cable
- Loose internal connection
- Overheating adapter
- Router hardware failure
If the problem happens on multiple networks, consider testing the computer with a different network adapter.
The Best Troubleshooting Order
You don’t need to try every solution at once.
Start With These Steps
1. Check whether other devices are affected.
2. Restart the router and PC.
3. Check Wi-Fi signal strength.
4. Forget and reconnect to Wi-Fi.
5. Restart the network adapter.
6. Update the network driver.
7. Check Wi-Fi power management.
8. Flush DNS.
9. Renew your IP address.
10. Test DNS using nslookup.
11. Temporarily disconnect your VPN.
12. Test another Wi-Fi band or Ethernet connection.
13. Reset Winsock and TCP/IP.
14. Check Windows and router updates.
15. Use Network Reset as a final Windows troubleshooting step.
This approach helps you identify the cause instead of changing many settings unnecessarily.
Final Thoughts
Random internet disconnections in Windows 11 don’t always mean your internet service is bad.
The problem can come from many different places, including your Wi-Fi signal, network adapter, driver, router, DNS configuration, IP settings, VPN, power management or ISP.
The most important first step is to determine whether other devices are also losing their internet connection.
If every device disconnects, investigate your router and ISP.
If only your Windows 11 PC disconnects, focus on the computer’s network adapter, drivers and Windows networking settings.
Simple solutions such as restarting your router, reconnecting to Wi-Fi, updating your network driver and restarting the adapter can often solve temporary problems. If the issue continues, commands such as ipconfig /flushdns, ipconfig /renew, netsh winsock reset and netsh int ip reset can help troubleshoot deeper network configuration problems.
And if you want to find the actual cause, don’t just keep changing settings. Use simple tests such as pinging your router, pinging an external IP address and testing DNS with nslookup.
With a systematic approach, you can usually narrow down whether the problem is coming from your PC, your local network, your router, or your ISP.
