Deco XE75 keeps re-enabling QOS uncommanded
My Deco network seems to randomly re-enable the QOS feature, which has the undesirable characteristic of limiting bandwidth to any one device, even when there is no network congestion (a useless and misleading feature in my opinion).
I consider it a bug that QOS re-enables itself from time to time.
Anyone else seeing this problem?

@LouK2 This is the first time I've seen different firmware versions for Hardware version x.0 and x.60, in your specific case hardware version 1.0 vs 1.60. Make sure you've updated the Deco app to the latest version and try again...

Not sure what you are referring to with the hardware versions.
I have two Deco XE75 units, both hardware version US/1.6, running Firmware: 1.4.5, with my Deco App Version: 3.10.12
I also have a Deco X50-Outdoor, with no visible hardware version on the bottom, but running Firmware: 1.2.8
I update them when prompted by the Deco app, and the app says they are "currently up-to-date".
Cheers,

For those who are following (or may search out) this thread, I thought I would post a summary of what Lemmy and Byron at TP-Link have identified:
1. It seems most likely that I inadvertently enabled QOS by toggling on the High Priority flag on one or more WiFi connected clients.
2. Turning on the High Priority switch on any client will automatically enable QoS for the entire network silently.
3. The way QoS is implemented is apparently going to have the side effect of limiting the bandwidth accessible to any one device, even if there is no network congestion, at least in some cases.
4. The above means that if you enable QoS, a speed test will possibly show a reduced maximum bandwidth accessible by any single client on the network, which in my case I found very confusing. Now that I know how QoS behaves, I can make a choice about whether or not to use it.
5. Since it is pretty easy to accidentally enable QoS, I will make it a habit to periodically check to ensure it is not enabled by mistake.
A big thank you to the support team at TP-Link who really dug into the case and helped me understand what was going on!
