Has anyone else encountered reliability issues with 5th Gen Airport Extremes? I've been suspicious of it crapping out for a while (this generation is known for a 'buzzing' noise on idle fresh out of the packaging). Im out of warranty and about to throw this thing out the window (and am even considering switching to a non-apple router for the first time in about 10 years). Do these results via iperf sound reasonable? The typical issue I am encountering -- across all devices -- is unreliable voice/video calling (packet loss/drops). Sustained download speeds are still fine, but my understanding is that getting Jitter under control is paramount for reliable VoIP/Video.
