Hi, Sean,
Sorry to hear you're experiencing this issue.
Your computer may have been locked because of a driver update, especially a Bios update and this update may have the wifi driver stop to working. Downloading and installing the latest version of the Wifi driver from your laptop manufacturer's website should fix this problem.
If the problem persists or you cannot find the correct driver on the manufacturer's website, provide the full model of your laptop and a screenshot of the system information and the version of the driver installed and I'll be glad to help you find the correct driver.
