Try different networks such as at your friend's house or Starbucks. If nothing is different, your tablet's wifi is not working, it's built on board, your only option is changing new main board. Depending on what model, used one is only around $50 to $60 on Ebay, or look for a working tablet with broken screen, if you're lucky, it's only around $40.
