Answer:
Check the hardware switch on the wireless antenna card that activates the service.
Explanation:
The person works for uCertify Inc as an IT Technician. David, a regular, has just buy a laptop. He still says that he will not link to a wireless connection, although his laptop seems to have an inner wireless app. So, by checking the hardware switch on the wireless antenna card that activates the service, that person resolves the issue.
