Samsung S3 wifi and mobile data not working. - Samsung S3

My wifi has stopped working and I write in the RIGHT password and then it comes up with 'authentication error occurred', my computer and laptop connect to it fine! And now my mobile data wont 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! And have look on the internet on my computer and have find that many people are having this problem since last year and im wondering why it hasn't been fixed! Its very annoying!!!
