My new Ipod TOUCH won't connect to my internet. I did "connect" to my wireless internet (I put in the password and everything) but for some reason it will only pick up the IP address and Sebnet mask, not the required Router and DNS. Will someone please help me?

1) Go to settings, Wi-Fi, choose the network and hit the blue button. Touch "Forget this network" and confirm.
2) Now go back into Wi-Fi settings, choose the network again and join it.
3) Now hit the blue button and go down to the DNS line. Select the line and drag your finger to the left until you find the first DNS entry (entries are separated by commas). In my case, for instance, the first entry was 192.168.1.99--a local address on my network.
4) Use the backspace button to delete the first DNS entry.
5) Touch "Wi-Fi Networks" to go back.
6) Open safari and try visiting a site by URL: Apple for example.
