1. Checking the Physical Connection and Computer Hardware
Before starting with software troubleshooting, ensure your hardware is functioning correctly:
- If using Ethernet, make sure your Ethernet cable is securely plugged into both the computer and router/modem.
- If using Wi-Fi, ensure that the adapter or built-in Wi-Fi card is enabled. On laptops, physically check for Wi-Fi switches or shortcut keys (such as Fn + F2, Fn + F8, or similar depending on the manufacturer).
- Restart your router/modem to rule out connectivity issues.
2. Running the Network Troubleshooter:
Windows 11 has a built-in networking troubleshooter, useful for diagnosing basic issues:
- Press
Win + I
to open Settings. - Click on System, then select Troubleshoot, followed by Other troubleshooters.
- Locate Network Adapter troubleshooter from the list, then click Run.
- Follow the on-screen instructions.
This step may automatically fix your adapter issue or provide additional diagnostic info.
3. Checking the Network Adapter in Device Manager:
The next step is checking device management:
- Right-click the Start button and select Device Manager.
- Expand the Network adapters section to see if your adapter is listed.
- Check if the adapter is disabled (indicated by a downward arrow sign). If so, right-click and select Enable device.
- If the adapter is showing with a yellow exclamation mark, it represents a driver conflict or issue.
If no adapter shows, move to driver troubleshooting and BIOS checks.

9. Performing a System Restore (If Needed):
If the adapter recently disappeared after installing software or updates, system restore could help:
