My Itouch doesnt have a wifi address anymore :\ how do i get a new address?

i didnt jailbreak it it happened when i went into the app from apple for liek controlling your computer or somethign and heres an edited version of what i said sorry i was really frustrated and didnt think of spelling

how do i get a new wifi address?...also it wont let me into the wifi section in the settings...and it like charges really fast when i was online b4 it lost the wifi and it wasnt being charged with the charger and it like lost the charge while being charged and right now it got full charge somehow and now it is down to 20% and it is plugged into my computer..................this all started after i went into one of the apps for it and it got bricked for like a couple minutes......as in the site for the apps that APPLE APPROVES...any help? plz lol

edit: also i have alredy restored it and reseted settings and all that crap and when ever it turns off it restarts automatically and i dont have a case on it and i am not touching the power button....this is gettign me mad<---hope that helps

ok here it is in simple terms ok. I didnt jailbreak it i used one of the applications that apple has on its site for the updates. It bricked my itouch for like a couple minutes. It started charging w/o a charger being plugged into it and when a charger was it would lose charge. It also turned back on as soon as i turned it off. Now it will not let me into the Wi-Fi area in settings as in the button for it is grayed out and reads No Wi-Fi in the about my itouch it shows it has no Wi-Fi address. How do i get another Wi-Fi address??? everything else works fine. What is wrong with it and i have already restored it using Itunes, reseted it through settings and i can not let it run dead because it will not run out of battery becuase it will not run dead with the charger in it because it wont let it past 10% and with it off( the charger off of it) the battery charges...So what can I do to GET A NEW WIFI ADDRESS IS ALL IM ASKING IS THAT SO HARD???? THE REST IS EXPLAINING MY PROBLEM OK????
