As weird as it sounds, $3000 machines still only come with one radio so it can only tune to one frequency at a time. Similar latency spikes happen when roaming

As weird as it sounds, $3000 machines still only come with one radio so it can only tune to one frequency at a time. Similar latency spikes happen when roaming between access points.
