Android Question

Just bought Samsung Galaxy S4 and it's amazing.
My question is why won't it read my wi fi at home?
I have a desktop computer through Charter communications.
Wasn't an issue with my old samsung.
Thanks you!
Make sure you're trying to connect to your wifi, not a neighbor's. If your router has WPS (or automatic setup or anything with a name like that), press the button and the phone will connect right up (if it's working correctly).
