The Service Set Identifier (SSID) is the network name for a wireless LAN. When a user notices another wireless access point using the same SSID, changing the SSID to a unique name can help avoid confusion and ensure that devices connect to the correct network.

The importance of configuring wireless settings, including SSID customization to avoid network overlap, is discussed in CompTIA IT Fundamentals, particularly in sections related to wireless networking configurations.
