Problem with Wi-Fi Connection!!!

[ilovenapoli85]

Hello everyone I have a problem with my BB 8900 Curve and the WiFi connection (I have no data plan with my carrier).
Let me explain the problem.
The connection works wonders. Everything from the browser to the various applications that have as an option the possibility to use the wifi.
Only after a certain time not specified (+ or - 30-40 minutes) applications that use the wifi do not work anymore, indicating the connection failure while the browser continues to function properly!
The only way to reoperation for other applications 30 40 minutes to restart the phone!
How do I fix this problem?
I did the "telnet" test and the screen is black ... I have the bullet markers of gray wifi, hotspot browser set to (only choice). I also tried other connection in the office at the home of friends on the road but all give the same problem.
Below I copy the the wifi diagnostics:

Strange, I think you need a data plan for WiFi to work.
Surprisingly everyone with wifi errors has a d link router. Change ur router.
