Why isn't my tablet's Wi-fi working?

AC Question

I have a Samsung Galaxy Tab E Lite. I've had it since Late January and it worked fine since then, but recently, I've had problems with the wifi. It says it's connected and working fine, but it isn't. Chrome doesn't work, nothing that requires wifi works. I've tried everything suggested but not one of them have worked. Please help, i'm getting extremely mad.
