Two things you need to make secure wireless connection work?

A

-encryption standard used
-SSID of access point

Service Set Identifier (SSID) of the AP and then the encryption being used (for example, WPA or WPA2). The SSID takes care of the “connection” portion, and the encryption takes care of the “secure” portion. After all computers are connected, consider disabling the SSID for increased security.
