sgtthompspn10, you might want to try this first. Some people have had issues with it like you are and found that this worked. At least its a try before you have to replace any parts.
1st - Goto Settings > General > Safari : and erase History, cookies and cache
Just as Chris Green mentioned in the first answer.
if none of these have worked for you
-reset network
-changing DNS
-factory reset
then try to instead of hitting the name of your network, in the settings... go to Other. Then type in the name of your network... for security click on WEP.
Of course you could also try to restore your ipod as well. Here is another way to attempt to reconnect. http://www.ipodtouchfans.com/forums/showthread.php?t=286385
Here is some more info http://discussions.info.apple.com/message.jspa?messageID=11689411#11689411 and http://www.mac-forums.com/forums/ipod-hardware-accessories/81240-ipod-touch-says-no-wifi.html
Of course these are just attempts to fix it, if it is software related. If none of these works you will have to open it up and make sure that all cables are connected. I believe that The wifi antenna is a part of the mainboard, so you would have to replace the entire board to replace the wifi. Good luck and let us know.
