Why won't wi-fi work on my ipod touch?

Home More advice Computers & Tech

Normally my ipod touch just automatically joins the network router but last night i cleaned my ipod screen and i turned my ipod on today and on the top left the internet signal strength bar things aren't there. So i go onto settings to click on wi-fi but the words are just gray and nothing happens when i tpye it and by wi- fi where it normally would say connected it says no wi-fi, what do i do?!?
