Hi. I just replaced the battery on an iPod Touch 1st generation that was working fine before, but now, after it's put all back together it works great except the Wi Fi option is just grayed out, saying "No Wi Fi". I suppose I must have bumped something when reassembling, but how do I fix it? Is it the small antenna wire at the top that is causing this or something else? Do you think I just need to re-align the antenna or is there something else that might have gotten mixed up?

Thanks for the help!
