You could try forgetting the WiFi network in the phones settings and it that does not help to into Settings-apps and if you can clear the cache and data in the storage part of WiFi.
No joy then create a back up and factory reset.
Finally a Samsung Experience Store or Samsung Service Centre location can run a diagnostic on the device.
