After last night's update, my desk computer won't connect to the internet. All other devices do connect. Troubleshooting leads to problems with the internet adaptor. How can this be remedied?

Since the problem started right after updates and other devices still connect, the issue is likely on this PC or its network adapter.

Try these steps in order:

Run the Network troubleshooter
Go to Start > Settings > Network and Internet > Status > Network troubleshooter and follow the prompts.
Reset the network stack from an elevated Command Prompt
Open Search, type Command prompt, then select Run as administrator. Run these commands one at a time in this order:
```
   netsh winsock reset
   netsh int ip reset
   ipconfig /release
   ipconfig /renew
   ipconfig /flushdns
```
Then check whether the connection returns.
Reinstall the Ethernet network adapter driver
This is especially relevant when the problem starts after a recent update.
- Open Search, type Device Manager, and open it.
- Expand Network adapters.
- Find the Ethernet adapter.
- Right-click it and select Uninstall device.
- Select Attempt to remove the driver for this device, then Uninstall.
- Restart the PC.
Windows should automatically reinstall the adapter driver after restart. Before uninstalling, it is recommended to download the latest network adapter driver from the PC manufacturer on another device and copy it by USB, in case Windows does not reinstall it automatically.
If the adapter still fails, use Network reset as a last step
Go to Start > Settings > Network & internet > Advanced network settings > Network reset, then select Reset now > Yes. Warning: this removes and reinstalls network adapters and resets their settings to defaults. VPN client software or virtual switches may need to be reinstalled or set up again afterward.
Confirm whether the issue is only this PC
If possible, try connecting another Windows PC to the same network. If that other PC connects, the fault is likely with this computer. If it also fails, the problem may be with the router, ISP, or adapter.

Hi. I'm David, and I'm happy to help you.

It is necessary to investigate this issue to understand the reason for it.

Please clarify the following:

1 = Does your computer connect to the internet via cable (Ethernet) or Wi-Fi?

2 = What is the status of the network adapter?

Press "Windows + X" and select "Device Manager";
Click on the "View" menu and select "Show hidden devices";
Expand "Network adapters";
If the network adapter is listed, right-click and select "Properties". Check for an error in "Device Status". If you see an error under Device Status, please share a screenshot.

If you can't identify your PC's network adapter, share a screenshot of the network adapters.
Use the shortcut "Windows + Shift + S" to use the screenshot tool. Or take a picture of the screen using a camera or smartphone and share it.

Also, share a screenshot of your system information.

Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the screenshot tool. Or take a picture of the screen using a camera or smartphone and share it.

Looking forward to your reply.
