Hi Sam,My name is***** will try my best to help you with your question.
First, try a reboot of the phone if you haven't already done so - power it off completely, wait a few minutes, then turn it on again.
If that doesn't work, do all other devices stay connected to your home wifi ok, except the S7 Edge?
If so, the phone likely has a software bug, glitch, or possibly even a virus; and you’re going to need to perform a full backup and reset on the device.
