Windows 10: Intermittent internet connection issue with WiFi - How do I fix?

I have a Dell laptop connected by wifi to a Deco M5 mesh wifi box that is plugged into a VirginMedia router. Nothing has changed in my setup recently but I am not getting regular but intermittent occurrences where my laptop is still showing as connected to the wifi but cannot connect to the internet.

I initially used to reboot the laptop to solve the connection issue but more recently have gone into the 'Network and Sharing Centre', selected my wifi network, clicked on 'Diagnose' and it has fixed the problem. Today it has happened twice so far. The first time it said 'Wifi doesn't have a valid IP configuration' and the second time it said, 'The default gateway is not available'. I have also rebooted the Wifi and the Router but the problem persists.

Any help is greatly appreciated.

Hello Trevor,

Thank you for posting your query on Microsoft community.

There are some reasons that causes this error connection reset. Let’s try to identify the root cause and apply the appropriate solution to fix this.

I suggest you to run the network troubleshooter first, and check if the issue persists. To run the troubleshooter, follow the below steps:

1. Press ‘Windows + X’ key.
   
2. Select ‘Control panel’
   
3. In the search box, type ‘Troubleshooter’ and then click ‘Troubleshooting’
   
4. Under ‘Network and Internet’ click on ‘Network adapter’ and click on ‘Next’ button.
   

Try to update the network adapter and check if the issue persists.

1. Press ‘Windows + X’ key.
   
2. Expand the network and adapter’
   
3. Right click on the device, and select ‘Update driver software’
   
4. Restart the computer and check.
   
5. You can also check for updates from the system manufacturer site.
   

Check proxy settings by doing the below steps:

1. Go to Control panel – Internet options.

I also suggest you to reset IP Address by following the below steps.

1. Press Windows key, and type ‘Command prompt’
   
2. Right click on it and select ‘Run as administrator’
   
3. Type the following command without quotes, and press enter: ‘netsh winsock reset catalog’
   
4. Restart the system once and check if the issue persists.
   

Try to disable Kaspersky firewall and check if that helps

1. Open the Kaspersky Internet Security program.
   
2. Click the ‘Settings’ button.
   
3. Click the ‘Firewall component’ option under Protection Center.
   
4. Select the ‘Enable Firewall’ option to remove the check mark.
   

Hope it helps. Please reach back if the issue persists.
