I bought my Galaxy J7 back in late November 2015. Starting last week, it wasn't connecting to my home WiFi. It said it was connected, but the internet wouldn't work. The past couple days I noticed that it's having trouble connecting to other WiFi signals as well, such as my school and work. I've tried restarting the phone, restarting the home WiFi router, turning off WiFi saving, and I have even done a factory reset on my phone. Still, the WiFi won't work. Any suggestions?

Sorry, I'm not sure what to do if it's grayed out. I would think if it's grayed out either it's not on or your provider doesn't allow to turn it off. Mine just had an on/off button.
