Hello Xeno,

• Regarding your problem, we would like to recommend you the following:
• Change the wifi network by manually selecting AX on 802.11 under the network adapter.
  • Right Click Wifi adapter
  • Click Properties
  • Click Configure
  • Go to the Advance tab
  • Select 801.11 AX Wireless mode
  • Click Ok
• If the issue was caused by updating the wireless driver, Rollback the driver to the previous working version.
  • For the Rolling Back driver version access the device manager page,
  • Under Network Adapters right click on Intel Wireless AX 210 and select properties.
  • It will open a new tab for device properties and click on the Drivers tab,
  • Click on Rollback Driver or Press R
  • A new prompt will pop up requesting to input the reason why Rollback Driver  was selected, Simply select Function was working with the previous version then click Ok
• In case the issue remains, you can perform a clean wireless driver. Corrupted files from previous installations of drivers can linger on a system which can cause driver updates to not work as expected. There are two different types of drivers, generics provided by Intel and Equipment Manufacturer drivers, that are customized to work with each specific system. The best thing to do is to use the drivers provided by the system manufacturer (OEM). Based on the Lenovo website, the latest version available for your device is version 22.10.0.7:

1. Go to Device Manager.
2. Expand the Network Adapters category.
3. Right-click your Intel Wireless Adapter and choose to uninstall it.
4. Make sure the option to Delete the driver software for this device is selected.
5. Repeat steps 1 through 4 until the option to Delete the driver software for this device is greyed out.
