To my knowledge, the only password that could be set/changed is when you log into to your DI524 web configuration page. Once the WiFi router is setup and running, you can also changed. There is no password required for your wireless clients (users). There is however a provision for Security key which could be WEP, WPA or WPA-PSK. All of these could be accessed upon entry to the web configuration page of the DLink DI-524.
This page is an emulator that can help you be familiar how things are done to configure your WiFi router.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
