This problem still exists on 2021 Macbook Pro M1 laptop. Every ~10 seconds there's a spike in network latency raising the ping responses from the router up to 300ms. Disabling the Location Services has no impact, but disabling Bluetooth solves the issue and I'm getting consistent ping responses. iPhone connected to the same router doesn't have this problem, same for a couple of Windows laptops - all can work fine with Bluetooth AND Wifi enabled at the same time.
