Samsung Galaxy Tab 3 wifi connection

My tablet automatically connected to wifi until yesterday. It stopped mid-sentence. Now it says authentication error occurred. What is this and how do I get back to normal?

The only way to verify if it works normal: try different network like at your neighbor or Starbucks.
If it's the same, the last resource is reset. If it's still not work at the first screen at setting up, your wifi chips are defective and you have to change mainboard.
Tab 3 has different models and screen sizes, I have no clue which one you have.
