I have just bought an ipod touch, but I am having problems connecting it to my router. I have entered the correct password, but cannot use the internet on the ipod. I go to the wi-fi settings on the ipod and the IP address and Subnet Mask are entered, but the Router and DNS boxes are blank. I don't know what to enter in the boxes. I am using a netgear router, with WEP 128-bit security.
