My Wi-Fi hasnt been working for the past few months. I have a first generation iPod touch and I just downloaded the 3.0 software. My house has a wireless network throughout the house, yet I don't get a signal or even a network listing under WiFi settings. I've tried coffee shops, airports, pretty much anywhere where there's wi-fi, and there still is not any signal or network listing. I read all the stickies, but all the threads just dealt with signal problems. Not with problems with networks not showing up on the iPod. Does anyone have any help on solving this problem?
