Hello,
The most simple thing to do when you have this problem is in Command prompt type Release IP and hit enter. After that type renew ip and hit enter. Your work should be done.
Hope this was helpful. Please feel free to contact us for further assistance.

ok so u need your WEP key that it might ask for and that is located at the bottom bar code of your modem plug it in a nd that should solve your internet problems

ok basically the problem with your ipod is that you either are not entering ur WEP key correctly or that you got your ipod from some corner shop down the street :) anyway, ur WEP key is probably not what you think it is because you have to have a router or other such wireless device for u to have one that works. but if u have it then make sure you go to router settings and then security and make sure it allows external devices to access its network, so it doesnt block the ipod. hope this helps :P if it doesnt, u better hope u have a warranty.......

Try removing any WAP, WEP first and see if the ipod can connect. Does the ipod see the connection?

Go into Preferances, go to Wi-Fi, touch the blue cycle next to the Wi-Fi router you're conected to. Scroll to the bottom of the page and touch "Renew Lease", touch "Renew Lease" in the pop up. This may or may not work the first time. Either way, power off your iTouch by holding the "Power button" then sliding the slider. Turn it back on, go back to Preferences/Wi-Fi... Renew Lease... Try to open Safari. If it doesn't work the first time, no worries, try it all again. This is the solution, but if your iTouch gets glitchy, it can take a few tries. The most I've ever seen was 3 complete tries... "Renew Lease, Full Restart (slide to power off), Renew Lease"... one. Repeat!

Hey, i had the same problem. I you already have a wifi connection and it still says, "Safari is not connected to internet" Goto settings. Click the blue arrow next to the wifi name, scroll all the way down and click renew lease. It should probably get the IP address right and you'll be good.

Hi,   The easiest way to download to your iTouch is directly to your iTouch via the Apple Store. The Apple Store icon is already on your iTouch. Just make sure you are near an internet connection via Airport or Wi Fi. Click on "Download" on the selected app, and then wait a couple of seconds. Your iTouch will indicate when the download is done and the app is installed. You will see the new icon on your your screen page.
  If you install from your computer, you will have to plug your iTouch into the computer and use the  iTunes app to control what you download. 
  I hope that helps.   Shari Dyer

Hit "Forget this Network", go to Settings > General > Reset > Reset Network. Worked for me.
