Configure a WLC with a new WLAN, specifying the SSID and security parameters.
Troubleshoot a client unable to connect due to an SSID mismatch.
❓ Frequently Asked Questions
Does hiding the SSID secure my network?
No, it just stops broadcasting the name in beacons. The SSID is still sent in plain text during connection attempts.
Can multiple APs use the same SSID?
Yes, this is how roaming is achieved in enterprise environments. Clients transition between APs broadcasting the same SSID.
