wifi cycles and then crashes the tablet.

My tablet suddenly started crashing/freezing. I have narrowed it down to something to do with the wifi. After a factory reset the only thing i did was try to connect to a wifi. It connects and the connection last for a few seconds then the wifi turns off on its own and begins to cycle. Shortly after that if not right away the whole thing freezes up and is unusable. Do you know of anyone i can take it to to get it fixed? Is it fixable?
