169 IP problem ......

As far as i have noticed this is the most common problem with an ipod not connected to wifi, and its a pain in the neck. i too have the same problem.

i have an ipod touch 3G with iOS 4.3.3. and i dont have a wireless router so i just create a ad-hoc connection from my laptop Sony Vaio running on Win 7. I was able to access the internet for a week, then i got the 169 IP adress problem. i had iOS 4.0 then. i have updated it to 4.3.3, i have reset the network connections, and on my laptop i have renewed my lease (or however you say it) I have tried it with 2 internet connections, but i have the same problem with both the connection. i keep getting the 169 ip address on my ipod. right now i think it is something with my laptop or my ipod.

can you please tell me a solution for this?

it would be MUCH appreciated !

thanx !
