Why each option

If a wireless network is not visible, the most probable cause is that the SSID broadcast feature has been disabled on the router, hiding the network name from standard wireless scans.

ASSID broadcast is disabledCorrect

SSID broadcast is a feature on wireless routers that makes the network's name (SSID) visible to devices scanning for available wireless networks. If the SSID broadcast is disabled, the network will not appear in the list of available networks, preventing users from connecting.

BWireless password has changed

A changed wireless password would prevent clients from connecting, but the network would still be visible in the list of available networks.

CFirmware update is required

A firmware update being required might cause various issues, but it's not the most direct or common reason for a network to be entirely invisible while other functions appear to be working.

DWPA2 is enabled

WPA2 is an encryption standard; enabling it would secure the network, but it would not make the network invisible; users would see the network and be prompted for a password.
