This is a true techy topic :) But the author proably mostly has expierence with bad environments (like apartment buildings with lots of competing WiFis) and/or cheap wireless devices or those which have to do severe compromises (e.g. style or size or battery runtime over RF performance). These were the issues I had: 1. SO's cheap wireless mouse produced WiFi interference -> massive packet loss 2. Small 2.4Ghz USB dongles plugged into USB 3.0 port (e.g. Logitech's wireless dongle or USB WiFi for RPi) -> USB 3.0 interference render the dongle unusable 3. The HTC 10 has a metal casing -> incredibly poor BT RF performance, causing massive drop outs (especially bad with my FiiO Q5 DAC/headphone amp, which has a massive aluminum case) 4. Client stays on AP with very poor signal (barely in range) instead of jumping to different AP -> retransmissions cause massive degredation for all other clients 5. Lots of APs running at full power in an apartment complex, paired with a router/AP that had low WiFi performance anyway -> bad everything All but the last can be solved relatively easy (okay, I didn't swap the HTC10 due to BT, though that really annoyed me; it's time eventually came when the battery lasted half a workday without using the phone for anything). Especially coordinated WiFi APs (like Unifi) are great. And even the last point was a non-issue both in our last apt (one well placed UAP for testing) and our new old house (four UAPs).
