ipod Touch Wi-Fi problem
I have the very same problem. My ipod touch 16GB shows a "No Wi-Fi" message and does not allow me to enter the configuration page anymore. I have a domestic wi-fi system, and my laptops work just perfectly, and so did the ipod until a couple of weeks ago.
I have reset, updated firmware to 1.1.3, sinc'd again and nothing changes. Do you think the wi-fi damaged somehow?
