My wifi and blue tooth stopped working.

I've had this ipod touch 2nd gen 8g for 3-4 years and it has worked great. There was a stage were I put it away and used my phone, but now I want to use it again. For some reason my wifi and bluetooth won't work. I have done a reset and restore with no luck. Wifi if grayed out and BT says unavailable. Can someone help me?
