Problem with SimpleWebServerWiFi example

Hello,

I'm traying to connect my Arduino UNO R3 with a WiFi shield. I'm doing a probbe with the SimpleWebServerWiFi. I notice that the connection its OK, but I can't see the Web.

The message in the console is:
Please upgrade the firmware
Attempting to connect to Network named: JAZZTEL_U

IP Address: 192.168.1.131
signal strength (RSSI):-51 dBm
To see this page in action, open a browser to http://192.168.1.131

When I'm traying to open http://192.168.1.131, it doesn't work. I don't know who to upgrade the firmware. ┬┐How can I do that?

How can I do that?

Have you even tried to search? I didn't think,so.
