After a Windows upgrade on a clerk's PC, Wi-Fi fails until a wireless driver update is installed. What does this incident illustrate for the technician?
Select an answer to reveal the explanation.
Short Explanation
After an OS upgrade, a stale wireless driver is like new city software talking to an old radio firmware—SSID name can be perfect and still get silence. The driver is what makes the NIC usable; update it before blaming the passphrase. Software stack first, then profiles.
Full Explanation
Client drivers make the wireless NIC usable to the operating system. After OS upgrades, outdated or missing drivers are a frequent cause of total Wi-Fi failure even when SSID and passphrase values never changed. Technicians separate driver/software stack issues from SSID naming or infrastructure passphrase rotation. Restore a working driver, then validate profile settings.
