Welcome to Android Central! Reverting back to a previous version of Android is a complicated process that requires rooting your phone, so I wouldn't recommend it. Can you give us more details about what's wrong with the wifi?

In the meantime, try booting into Recovery and clearing the system cache partition. You won't lose any personal data: Reset: Samsung Galaxy S 4 | T-Mobile Support
