WPS (Wi-Fi Protected Setup) Settings

Router's PIN

This is the PIN number you use on a registrar (for example from the Network Explorer on a Vista Windows PC) to configure the router's wireless settings through WPS.
You can also find the PIN on the router's product label.

Disable Router's PIN

Only when the router's PIN is enabled can you configure the router's wireless settings or add a wireless client through WPS with the router's PIN number. This Router's PIN function may be temporarily disabled when the router detects suspicous attempts to break into the router's wireless settings by using the router's PIN through WPS. Users can manually enable this function by unchecking the option and clicking the Apply button.

Keep Existing Wireless Settings

This indicates whether or not the router is in the WPS Configured state.
If this option is not checked, adding a new wireless client will change the router's wireless settings to an automatically generated random SSID and security key. Please note that if this option is checked, some external registrars (e.g. Network Explorer on Vista Windows) may not see the router.
Configuring basic wireless settings from the router's management interface results in this option being checked.
