Wi-Fi Not Working On Lenovo? Try Troubleshooting Methods

If your Wi-Fi is not working on a Lenovo Laptop or if it refuses to connect to the network, it may be due to incorrect network settings. This may also happen when you try to connect your device to a new network or if you have recently changed/upgraded the hardware. 

As the problem can be triggered by both software and hardware issues, we’ll check the fixes for both problems to get your device’s Wi-Fi up and running again.

Perform these basic troubleshooting steps first to see if they solve the issue

  • Press the Fn + F5 or F8 keys to Enable Wi-Fi
  • Disable Airplane mode from the Action center
  • Toggle the Wi-Fi hardware switch to ON (available on select Lenovo models)
  • Perform a cold boot on your Lenovo device
  • Restart the Wi-Fi router
  • Disable any VPNs and/or proxy settings

Run the Network Troubleshooter

The first solution is to run the network troubleshooter. The troubleshooter tries to detect any issues with the hardware and tries to solve it. If the troubleshooter fails to solve the problems, it will then suggest solutions to help fix the issue.

  1. Press the Windows key + I to open Settings
  2. From the System tab, go to
    Troubleshoot> Other troubleshooters
  3. On the Network adapter, click on Run
    run network troubleshoot
  4. On the troubleshoot window, select the Wi-Fi adapter and click on Next
    wifi adapter troubleshoot
  5. Follow the on-screen prompts and solve any issues
  6. Restart your device if prompted and see if the Wi-Fi works again

Reconnect Devices

Another solution is to disconnect and forget the device from the network. The process will remove all the configurations and settings of the network. After then, reconnect it to fix the issue. 

To disconnect the device,

  1. Open Settings and click on the Network & Internet tab
    wifi settings
  2. Now click on
    Wi-Fi> Manage Known Networks 
    manage known networks
  3. From the list, click on Forget to remove the network information from your device
    forget known networks
  4. Enter the security key and SSID (if necessary) to reconnect to the network

Turn off Location Services

If the Wi-Fi signal on your Lenovo device is fluctuating and is not stable, it might be due to errors caused by Location Settings. Some users have reported that turning the service off has solved the Wi-Fi stability issue.

  1. Open Settings and click on the Privacy & Security tab
  2. Scroll down and from the App permissions, click on Location
    location settings
  3. Inside, click on the Location services toggle to deactivate the service
    disable location settings
  4. See if the network reliability issue is solved

Enable Wireless Adapter

The wireless module communicates and sends/receives signals on your device. If it is disabled, the device will fail to connect and communicate wirelessly. To fix this, enable the wireless adapter from the control panel or the device manager

  1. Press Windows key + R to open Run
  2. Type control to open Control panel
    control panel
  3. Now, Click on the following options
    Network and Internet> Network and Sharing Centre
    network and sharing
  4. On the left, click on Change adapter settings
    change adapter settings
  5.  Right click on the wireless network and click on Enable. You will need administrator privileges to change this setting
    enable wireless adapter

To enable the Wireless adapter from the Device Manager

  1. Open Run and type devmgmt.msc to open the Device Manager
  2. On the Device manager, double-click on Network Adapters to expand it
  3. Right-click on the wireless adapter and then click on Enable
    enable wireless device
  4. Try to connect to a network and see if it works

Enable WLAN Services

If the WLAN service is disabled, it can cause your Lenovo device to stop discovering and connecting to any wireless networks. This effectively stops the network services and posts this error. To remedy this problem, you will need to enable the WLAN service from Windows Services 

  1. Open Run and type services.msc to open Windows Services
  2. From the list, search for WLAN AutoConfig and double-click to open it
    wlan auto config
  3. On General, click on Start to enable the service. Also set the Startup type to Automatic
    wlan configuration
  4. Click on Apply and OK to save changes 

Reset TCP/IP Stack

Another method to solve this error is to reset the TCP/IP stack. This process resets the DHCP and the TCP/IP configuration from the system registry by restoring the values to default.

  1. Open Run and type cmd 
  2. Press the Shift + Ctrl + Enter keys to open the command prompt with elevated access
  3. On the command console, type the following and press the Enter key after each line
    ipconfig /release
    ipconfig /flushdns
    ipconfig /renew
    netsh int ip reset
    netsh winsock reset
    netsh int ip reset <File directory:\>resetlog.txt
    [eg: netsh int ip reset C:\resetlog.txt]
    int ip reset log
  4. Close the command prompt and restart your device to complete the process

Update/Reinstall Drivers

For this fix, first, update any existing Network adapter drivers. If that fails to solve the issue, uninstall the drivers and install them again.

To update the drivers,

  1. Open Run and type devmgmt.msc to open the Device manager
  2. From the list, double-click on Network adapters to expand it
  3. Right-click on the wireless network adapter and select Update device
    update driver
  4. Select if you want to perform a manual or automatic update
    driver update automatic manual
  5. Restart the device after the process completes

To uninstall the drivers, 

  1. On the Device manager, right-click on the driver and click on Uninstall device
    uninstall driver
  2. If a confirmation box appears, click on Uninstall again to proceed
    uninstall confirm
  3. Restart your device to complete the process

If the drivers are not installed automatically after a restart, you will need to download them from the adapter manufacturer’s support page.

Reset Network

Another common solution is to reset the network from Windows Settings. This setting will then forget any saved network and device information. 

  1. Press the Windows key + I to open Settings
  2. From the Network & internet tab, click on the Advance network settings
    network and internet
  3. Scroll down and click on Network reset
    network reset
  4. Click on Reset now and on the confirmation, click on Yes to proceed
    reset now
  5. Wait for the restart process to complete and then see if the issue is solved

Reset BIOS Settings

The final software fix is to reset any changes made to the BIOS. By changing the BIOS settings to default, you will also revert any configurations made to the hardware. Naturally, this process will also restore any settings made to the network hardware as well.

  1.  Restart your device and repeatedly press the BIOS key to gain access 
  2. On the BIOS, search for setting that restores the BIOS to its default setting
    reset bios
  3. Press the associated key and reboot your device normally
  4. See if the Wi-Fi works on your Lenovo device now 

Check Hardware

The last solution is to check the hardware. If the devices are loose or are inserted incorrectly, reseat them and restart your device to see if they work properly. 

For desktops,

  1. Turn off your PC and remove the power cables

  2. Press the power button for at least 10 seconds to remove any residual power

  3. Remove the side panel to gain access to the internals 
  4. If you have a Network expansion card installed, reseat it 

For laptops,

  1. Turn off your laptop and remove the battery

  2. If the battery is non-removable, remove the back cover and disconnect the battery from the motherboard
  3. Press the power button for at least 10 seconds to remove any residual charges

  4. Disconnect any cables attached to the wireless module and remove it from the slot
  5. Reconnect the wires and reseat the wireless module
