Welcome to the Cisco Home Community.
Wi-Fi Protected Setup Button - If you have client devices, such as wireless adapters, that support Wi-Fi Protected Setup, then you can use the Wi-Fi Protected Setup button to automatically configure wireless security for your wireless network.
You can turn to page 20 of your userguide or click this link.

The button is used to setup WPS which is an automatic way of securing your wireless connection by means of pressing that and one on your wireless adapter's software (which some Linksys devices have).
I think this article here would clear that up
Some devices have it, and some dont...
Since you already have wireless security on your network, pressing that would change the wireless security codes.
Therefore, I suggest you not to press it anymore...
