Windows 7 Problem with connecting to Ad Hoc Network

[hackalldevices]

So im running on Windows 7 and when i create an Ad Hoc network my ipod touch discovers it and connects but gets a 169 ip address and the DNS, subnet mask and router fields are empty. Under wireless connection properties i have ipv6 disabled and ipv4 enabled. Under ipv4 properties, if i have it set to optain all the information automatically i get the same problem. If i set the fields manually i still get a message when trying to open safari on my ipod saying 'cannot open page' safari cannot open page because it is not connected to the internet. Ive successfully connected to my ad hoc net work before with my ipod touch but now im not sure whats wrong. im using:
cricket broadband to connect to the internet
Atheros AR298X Wireless Network Adapter

ive tried all the solutions the internet has had to offer with google but ive had no luck. Could anyone help me out? I have ICS on.
