network connection

We are connected to the internet physically but our apps will not recognize the connection.

We have flushed and reset the dns and networking caches.

Hi, @dwallace1@indy.rr.com

If you haven’t tried it yet, first, restart the PC and your router/modem, then test the apps again.

If the issue still persists, to help narrow down the issue:

What type of connection are you using, Wi-Fi or Ethernet?

Is this a home network, or are you connected through a work or school environment?

Do other devices on the same network connect to the internet normally?

Also, which apps are showing that there is no connection?

Since DNS and network command resets were already tried, the next supported steps are:

Run the built-in Network troubleshooter:
- Go to Start > Settings > Network and Internet > Status.
- Select Network troubleshooter.
- Follow the on-screen steps and check whether apps start detecting the connection.
Test the same network on another device:
- If another Windows PC can connect normally on the same Ethernet network, the issue is likely on the original PC.
- If the second device also fails, the problem is more likely the router, ISP, or Ethernet adapter.
If the PC has Wi-Fi available, connect to Wi-Fi temporarily:
- This helps confirm whether the issue is limited to Ethernet.
- If Wi-Fi works and Ethernet does not, focus on the Ethernet adapter or its driver.
Reinstall the Ethernet adapter driver.
- Risk: this temporarily removes network connectivity until Windows reinstalls the driver or a backup driver is installed.
- Before uninstalling, download the latest network adapter driver from the PC manufacturer on another device if needed.
- Open Device Manager.
- Expand Network adapters.
- Right-click the Ethernet adapter > Uninstall device.
- If shown, select Attempt to remove the driver for this device > Uninstall.
- Restart the PC.
- After restart, Windows should reinstall the adapter driver automatically.
Use Network reset as the last step.
- Risk: this removes and reinstalls network adapters and resets their settings to defaults. VPN clients, Hyper-V virtual switches, and similar networking software might need to be reinstalled or reconfigured afterward.
- In Windows 11: Start > Settings > Network & internet > Advanced network settings > Network reset > Reset now.
- In Windows 10: Start > Settings > Network & internet > Status > Network reset > Reset now.
- Restart and test the apps again.

If the apps lose connectivity only under a local proxy tool, one documented cause is a system proxy intercepting traffic; some apps reject that traffic because of certificate pinning.
