I have the first version of the iPad and lost my wifi.

I couldn't understand why I lost my wifi on my first version ipad. I did a hard reboot and I attempted to sync it to my new mac computer. I soon realized all my old apps and wifi option on my ipad disappeared. My old computer has a virus and I attempted to sync to the itunes on that account but I cannot update the itunes account on that computer for some reason so I cannot sync it to the old computer. what do I do to have the ability to even enter a wifi account on this ipad. Under settings....the wifi says...no wifi and doesn't even let me select the option. I tried going under general...then network and once again....it says VPN...not connected....then wi-fi Says no wi-fi. My apple computer has the wifi account listed...cannot sync to it. Very frustrated.
