Need help from a Samsung phone guru

I have a Samsung Galaxy J3 smart phone model SM-J337U. Up until recently, I've been able to access the internet while out and about on the phone. However, a while back, I was in Home Depot trying to use their app to locate something in the store and it said I didn't have an internet connection. Then last week same thing happened at Safeway and just today, I was at Best Buy and wanted to do a curbside pickup.

I opened the email (which I had opened before I left home) and clicked on the link in the email that should connect me to the store to tell them I was there and the same thing popped up... No Internet Connection.

I've obviously messed up my settings, but I can't, for the life of me, figure out what setting I need to change in order to get it back.

Can anyone out there help me?
