Vox WiFi turns on and then off

Vox working fine yesterday. Today the Wi-Fi doesn't work. I turned the WiFi on, waited and then about 30 or 60 seconds later it turns itself off. It didn't allow me an opportunity to scan for networks or anything. No message.

My Palm TX and my laptop work just fine on my WiFi connection. I have power restarted my Wireless Access Point but no difference. Turning airplane mode on and off made no difference.

Any suggestions?
