Hello and welcome, serge.
Does your S4 behave the same way no matter which wifi network you're using? If you have not tested that yet, it might be a good idea to do that because if it's just one router with the issue, well, that might be the issue: the router.
It could be a setting in the router or it could be firmware needing to be updating. Routers have a provision for updating the firmware somewhere in their settings area.
Some find success by resetting the router, often via a tiny pinhole which you insert a pin or other small thin object. Some have a reset button, and some are reset by merely unplugging them from the power source (along with the router/data cables) and waiting a full minute, then plugging back in.
But again, first tell us if the phone is ok on other networks or not. If it shows that behavior across more than one wifi network, we may have some configuration to do or a factory data reset.
