Hi PeterY61 ,
try these options:
1) Uninstall / reinstall the wi-fi adapter by following this procedure:

**NOTE:**This is a non Microsoft website. The page appears to provide accurate and secure information. Beware of ads on the site that may advertise products often classified as PUPs (potentially unwanted products).
Ignore advertising tips, do not use third-party driver installation programs.
2) Try changing the driver by looking for it on your computer:
- Go to Device Manager> Network Adapters, right click on your network adapter> Update Driver.
- Select "Search my computer for drivers"
- Select "Choose from a list of drivers available on your computer"
- Windows will propose 2 or more compatible drivers for the network adapter in use, select a driver other than the one currently in use> Next. The driver will be installed automatically. Restart the PC.
Otherwise, download and reinstall the latest driver version available from the pc manufacturer's website
