Service Set Identifier (SSID) is a unique name that identifies a particular Wireless LAN. It is set by the administrator and all clients need SSID to connect to the wifi network. But, the SSID can be discovered by network sniffing/scanning. All wireless devices on a WLAN must employ the same SSID in order to communicate with each other.
Common examples of pre-defined SSIDs are simple names like wirless, netgear, belkin, linksys, wireless etc but SSID’s can be changed at any time, as long as the change is also made on all wireless clients.
Here are some tips to choose a secure SSID
- Never use your name, address, birthdate, passwords or other personal information as part of the SSID.
- Choose SSID that contains both letters and numbers
- Choose an SSID as long or nearly as long as the maximum length allowed.
- Change your SSID every few months.

- In the administrative console navigate to Wireless Settings page and enter your new SSID in the Wireless Network Name field.
