50 Chapter 3 Wireless LAN Network

3 When the wireless client finds an OTIST-enabled AP, you must still click Start in the AP

OTIST web configurator screen or hold in the Reset button (for one or two seconds) for

the AP to transfer settings.

4 If you change the SSID or the keys on the AP after using OTIST, you need to run OTIST

again or enter them manually in the wireless client(s).

5 If you configure OTIST to generate a WPA-PSK key, this key changes each time you run

OTIST. Therefore, if a new wireless client joins your wireless network, you need to run

OTIST on the AP and ALL the wireless clients again.
