I tried to create an ad-hoc network for my iPod touch by creating a new one on my Windows 7 laptop. I have broadband and I wish to create a wireless network so I can use wifi on my iPod touch. But every time I try to join it on my iPod touch, I get a "Unable to join the network 'Laptop'". The network has a WPA2-PSK password and a radio type of 802.11bg. Why is this happening???
