To use WPS, you must: 1) Press the button on your WiFi/WAP device 2) Select the configuration on your BB for WPS setup
You must do all of that within a limited timeframe...often not more than 2 minutes is allowed for WPS to remain active on your WAP. If you wait too long, the session will expire and your BB won't be able to find any active WPS sessions to attach to.
Occam's Razor nearly always applies when troubleshooting technology issues!
