Slow Download Speeds R710 Unleashed

[max_p_eogltxsc8]

Strange issue with R710 on latest unleashed firmware. Upload speeds consistently incredible on both laptop and phone but downloads even from 5 ft away never go over 200 but stay consistent through 3 thick walls. Speedflex on android shows 550 up 550 down to AP. Iperf reflects speedtest.net results. Cable shouldn't be the problem as I have plugged my laptop on it and gotten the gigabit fiber speeds I should be getting. I have factory reset it countless times set everything to auto and tried manually setting the bands and channel width, am I missing something? Any help would be appreciated.

Unfortunately, I spoke too soon. While the performance problem is fixed, now it's a reliability problem.

My clients ramdomly get disconnected. Sometimes they reconnect, sometimes that can't without turning WiFi off and back on. I suspect something's going wrong with the handoff when the clients roam or maybe when the APs change channels? I don't know.

Clients can cope poorly with channel changes. If you're seeing clients get disconnected frequently, the first troubleshooting I'd recommend is to assign channels statically for all APs. For most Unleashed-sized networks, this shouldn't be too tedious.

Already on 200.8.10.3.278 and iOS devices still having vastly different performance to non-iOS devices.  Uploads are stable, downloads start fast then drop immediately, if lucky they come back up.  This is testing a few feet from APs, tested with multiple iOS devices and multiple APs.  All APs are R320s.

So... after all this drama and 200.8.10.3.278 turning out to be stable and fix most of the speed issues, I upgraded one AP over to 200.9.10.4.202 and almost instantly it has reverted back to the subpar speeds seen this thread has been posting on previously.

Why is this happening? Without even going into major details, simple Speedtest.net in 200.8.10 yielded 448Mbps/524Mbps (symmetrical 500Mbps circuit) and on 200.9x it dropped back to 329Mbps/363Mbps. Putting back the original firmware and restoring the conf on it instantly brought the speeds back to what we have been experiencing with the 200.8 fix (almost matching the Speedtest before the upgrade).

 I sincerely hope this is not a repeat of the whole 200.6>200.7 drama that started this whole issue years ago. Is anyone else seeing these speed issues with the new firmware (that I believe was being touted as the new fix for all platforms that has speed issues that 200.8x didn’t fix earlier this year).

I am using 200.8.10.3.290 on T710, seems the issue still exists. I got around  250Mbps/700Mbps, very poor for downloading. Is there a final fix?
