A couple of things happened recently
1) People upgraded to IOS14
2) I updated the controller and devices to the latest firmware (new interface)
IOS Clients behaving funny; keep dropping back to 2.4ghz
IOS Clients 5ghz throughput very poor compared to historic averages. I.e. 70Mbps vs 450Mbps
IOS Clients with very high jitter; 15-35ms - likely the cause of slow throughput
Whitnessed IOS clients keep switching between 5ghz and 2.4ghz. Band steering was not and never has been enabled. Only since the two upgrades (mentioned above) has this behaviour been observed.
Convinced the slow speeds and jitter was due to the IOS devices switching to 2.4ghz randomly.
Some speedtests are max speed still, most are not
So i turned off 2.4ghz thinking this will solve the high jitter - sadly it didnt! I am quite shocked
So either the high jitter on IOS clients is down to IOS14 or a misconfiguration i have somewhere.
Any ideas? I know Ubiquiti have had some issues with IOS14, but i'm just raising this here in case i missed something, or if its firmware related, the TP-Link team can investigate.
p.s. I have methodically tested speeds and stability with laptop devices on exactly the same channel in the same location at the same rough times and all but IOS14 devices are absolutely fine.
I have also very carefully checked for interferance and signal levels, not that anything has changed recently and the 5ghz airwares are clean.
This illustrates the issue, despite it reach a fairly decent speed, this was an isolated test with no other clients, with a connect rate of 800Mbps+ and should theoretically reach 400Mbps / 450Mbps.
