Samsung S4: Can't Turn On Wifi

Hello. I have a Samsung S4 and it can't connect to my home wifi. When I try to turn wifi on my phone it automatically switches back to off. This problem happened after I turned off airplane mode. Before that it connected fine. Any ideas about how to fix this?

Welcome to Android Central! Does it persist after a reboot? How about a cache partition wipe? http://support.t-mobile.com/docs/DOC-5744
