Sorry to hear your having issues with your Samsung device, to confirm your having issues connecting the phone to the WIFI (you are not trying to use 3G or 4G)?
Good evening its been some time since I have heard back from you.
I would start by restarting the router, and then see if you can connect to your WIFI in some cases the router can lock up and stop new devices joining.
Do let me know if you need anything further.
