RBR760 Slow Wired Speeds

So I had very similar issues with the RBK753 system so shame on me for purchasing the RBK763 hoping for better... 

 

Wired devices have slower speeds than wireless devices and, to me, it seems to be some kind of QoS functionality that seemingly cannot be turned off.  For example, I can start a download and it starts at 100Mbps and sustain that speed for only a few seconds before getting ramped down and down and down to around 20Mbps.

 

I'm fairly certain this has to be a common issue with this hardware but I have not been able to determine a resolution.  I've tried various things like disabling IPv6 and UPnP based on these things seeming to work for other people in similar situations but this does not work for me.  I have also replaced the ethernet cables between the modem and the router and device(s) in question.

Is anyone aware if there is indeed some QoS that these devices employ and, if so, can it be disabled?

I am not aware of any default QoS features in the Orbi AX systems that cannot be disabled.  What you describe (slow wired speeds) is not commonly reported here.  Your situation is also curious because why would wireless traffic not be affected but wired does?

How many wired devices do you have that exhibit this issue?  If only one, the issue may be with that device itself and that would explain why it persists after replacing your older Orbi.  Please explain that device, its version and OS, and in detail how it connected wired to the network.  Is there a network dongle, a switch inbetween somewhere, etc.?

Fortunately there are some simple tests you can try.  Connect your wired device directly to the modem and see if the problem occurs.  Then connect wired directly to the Orbi base and do the same.  The results will help us determine next steps.
