After a new USB Wi-Fi adapter is plugged into a municipal help-desk PC, Device Manager shows a yellow warning and no networks appear. What is the most likely connectivity fault class?
Select an answer to reveal the explanation.
Short Explanation
Yellow bang on a brand-new adapter usually means “no driver yet.” Until the OS can talk to the NIC, scanning the city’s SSIDs is a fantasy.
Full Explanation
Missing, corrupt, or uninstalled WLAN drivers prevent the adapter from operating, which blocks discovery and association. A Device Manager warning on a newly added adapter points to a driver issue rather than successful security config, cached captive portal pages, or unrelated remote SSIDs.
