Catalina Update

My laptop can't connect to wifi after Catalina update. none of the apps which needs to be connected to wifi could work. Although other phones and laptops in the house can. Any ideas on how I could fix it?

Repair the Drive for El Capitan or Later


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility and press the Continue button.
  3. Then select the indented (usually, Macintosh HD) volume entry from the side list. 
  4. Click on the First Aid button in the toolbar and wait for the Done button to activate. Click on it, then quit Disk Utility.
  5. Select Restart from the Apple menu.
