Can't Connect First Gen Ipod to Wifi; WPA2-PSK stuff

I got this ipod two years ago and left it for awhile, since it wouldn't connect to my internet at home, but now I need it

Its a first gen, 3.1.3 version

So the reason why I sumbitted this question was because, under setting and wifi, "Other..." does not have the option of WPA2-PSK but it does have WPA and WPA2 and the enterprises

I do this because my witeress router does not show up, sadly.

I do not want to change my secruty of my router, since that would mean I would have to change my parents computers alot, which takes alot time and they get mad if I touch the router (Also I tried doing this before for my old ds but it didn't work, and I had my smart friend do it and he couldn't do it either!)

So... Is there any other way of doing it? Perhaps a jailbroken software/app to add more internet connection options??

Please help!
