Ipod Touch Internet Glitch, Help!?

Hello everyone! I am having a big issue with my ipod touch 2nd generation right now. I turned it off, the other day which caused it to forget my internet network. So then today i tried to reconnect to the network. I must have typed in the password (WEP key) in several times, and i make sure that there are no misspellings in the password, it WILL NOT let me connect. My modem is fine too, all the lights on it are green like they are supposed to be. Im wondering if its something with the ipod? Does anyone know how to fix this? let me know! 10 points to the one who gets it! Thanks!
