S3 Wifi Authentication Error and Mobile Data Not Working

My wifi has stopped working. I type in the right password and then it comes up with 'authentication error occurred', but my computer and laptop connect to it fine! And now my mobile data won't work. I turn it on but when I click on the internet it says there is 'no internet connection' even when I have four bars! I have tried many things! I have looked on the internet on my computer and found that many people have had this problem since last year and I'm wondering why it hasn't been fixed! It's very annoying!!!
