2 ways to find out without opening the console. Either try another ps4 in the same location to rule out a wifi signal issue or interference or you can take the ps4 somewhere else with wifi and see if you run into the same issue. The antennas dont really go bad unless the console has physical damage. Also check the speeds when you do the internet test. If they are low, move the console closer to the router and see if its improves.
