Hi Ingrid.
I'm David, and I'm happy to help you.
See if one of the procedures below helps fix this issue.
Reset the network settings:
- Press "Windows + I" and select "Network & Internet > Advanced network settings";
- Select "Network Reset";
- Select "Reset Now", and at the confirmation screen, select "Yes";
Note: The PC will need to be restarted.
- Now open Start and type cmd;
- Right-click on "Command Prompt" in the result list and select "Run as administrator";
- At the Command Prompt, type the following commands one at a time and press Enter:
netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
- Restart your PC and see if the issue is resolved.
If it persists, reinstall the Wi-Fi driver.
Before starting the procedure, go to the support area of the Lenovo website and download the latest Wi-Fi driver.
(If you cannot find it, let me know the exact model of your Lenovo laptop)
Uninstall the current driver:
- Open "Device Manager" (Windows + X and select Device Manager);
- Expand "Network adapters";
- Right-click on the Wi-Fi adapter and select "Uninstall device";
(It may have more than one adapter, if you don't identify the correct one, send a screenshot "Windows + Shift + S")
- On the confirmation screen, check "Attempt to remove the driver for this device" and click "Ok";
- Restart the PC.
Install the driver you downloaded from the manufacturer.
I hope this helps. Feel free to ask back any questions.
