Your only choice right now is to narrow it down one by one and isolate the issue to see where is it coming from.

Try removing all the nodes and remain one main node first and test it through Wifi and LAN, to see whether is the ethernet port behind of the deco is malfunctioning.

Yes, is going to be very trouble some and cause some network down issue on your end but that deco is not cheap, and I will definitely send in for a warranty if the thing is a defect.

As I noticed there aren't any firmware for BE65 and your BE85 is at the latest version as of now, Build 20241023.

Try swapping both BE 65 and 85 as the main nodes and make sure no other nodes are connected to it.

From there on, test all of the ethernet ports and do a Wifi speed test again to isolate and narrow down which deco is causing you the problem. I highly don't think 2 of it will be exhibiting the same problem. Is either one of it, or the ethernet ports or is an entire firmware issue which is causing this slow upload bug.

It could also be the Wireless settings that are causing this bug, example

320Mhz
MLO
Smart Connect ; 2.4Ghz+5Ghz all banding up together.
Eco Mode

So my suggestion, is turn off all this Wireless settings or LAN settings, and test it one by one.

Everything must be isolated one by one to see whether is a settings issue or a firmware issue. From there you can show it to the TP-Link engineers and pray that they will be able to solve the problem on the deco itself.

Once you managed to get to the root of the issue, you can send in a support ticket to them, they will arrange for a TeamViewer session and ask for access to your homenetwork through remotely and help you to diagnose through SSH and PuTTy. From then on, they will take your case very seriously and work out for a firmware fix ASAP. I've experienced that process once before for my Deco X50 when the Weekly Reports wasn't working at all.

I see, i will try once there are no one using the internet.

using de85. highly recommend it. even with clients connected to "office" mesh which is two hops away wirelessly from main unit i can get 1gbps speed test. three storey house from top floor to bottom

Have you try Test Internet Speed in the Tp-Link DECO App and also change the Device Type for each client?
