Hi, my name is Travis. The only Mac product I have is an Itouch. OK, to start off, after I did this update from the Itunes store a while ago, after that my Wifi stopped working...it has a grayed out "No-Wifi" and I can't touch the option to turn the wifi on either. I'm really getting frustrated with this problem...I tried to restart my network to default, restored my Itouch countless times. That didn't solve the issue either. I DO have a wireless Modem, and I can connect wireless with my laptop. My main computer is a Desktop. But, anyways I would really appreciate if someone could help me with this problem. Apple didn't help me much since I don't have a warranty anymore. So, just please reply to this thread, and give me some troubleshooter ideas.
