How to Fix Windows Not Detecting WiFi
Windows computers failing to detect WiFi is a common issue that can prevent internet access, affecting both work and entertainment. This article will introduce several effective solutions to help you quickly restore WiFi connectivity.
1. Update Device Drivers
Outdated or corrupted drivers may cause Windows to be unable to detect WiFi. Ensuring your drivers are up to date can effectively prevent this issue. It is recommended to use Driver Sentry to automatically detect and update drivers, saving time and reducing the risk of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry, install and open the software, then click "Scan".
After the scan is complete, the software will display any missing or outdated drivers. Locate the wireless network driver in the list and click the "Upgrade" button.
Once the update is complete, restart your computer to ensure the new driver takes effect.
2. Check Basic Settings
Ensure WiFi is Enabled:
Press Win + A to open the Action Center and check if WiFi is turned on.
Some laptops have a WiFi switch or a function key (Fn + WiFi key)—make sure it is enabled.
Restart Your Router and Computer:
Turn off the WiFi router, wait 1-2 minutes, and turn it back on.
Restart your Windows computer to reload the network settings.
3. Restart the WLAN AutoConfig Service

In the Services window, locate "WLAN AutoConfig".
Right-click the service and select "Start". If it is already running, choose "Restart".

Check if your computer can now detect WiFi.
4. Reset Network Settings
Open Settings and go to "Network & Internet".
Select Status from the left menu and click "Network Reset".
On the Network Reset page, click "Reset Now".
After the reset, your computer will restart automatically. Once it reboots, reconnect to WiFi.
5. Run Windows Network Troubleshooter
Open Settings and go to "Update & Security".
Select Troubleshoot from the left menu, then click "Additional Troubleshooters".
Find "Internet Connections" and click "Run the Troubleshooter".
The system will automatically scan and fix possible network issues.
Restart your computer and check if the WiFi connection is restored.
6. Modify DNS Settings
Press Win + R, type "ncpa.cpl", and press Enter.
Right-click the Wi-Fi adapter and select "Properties".
Choose Internet Protocol Version 4 (TCP/IPv4) and click "Properties".
Select Use the following DNS server addresses and enter the following DNS:
Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4
Click "OK", then restart your computer.
By following the steps above, you should be able to diagnose and fix the issue of Windows not detecting WiFi and restore your connection. If the problem persists, consider seeking assistance from a professional technician for further troubleshooting.
