Slow file transfer between clients on LAN?
I have been using my 3 Deco M9 Plus for about 6 months and they work great but there one problem. Whenever i fransfer a file from one client to another the speed rarley goes above 100mbit. The clients are connected to eth on the Deco's and the speeds are the same no matter what protocoll i use FTP,SMB. All my clients reaches speeds of 250mbit to the internet so the network seems to work fine besides the slow client to client file transfer.
Is this normal or am i missing someting here?

You would frist need to check your connection link rate on each computer. Make sure its 1000 Mbps or 1 Gbps. After that make sure your NICs are set to Full Duplex. Then test the connection rate again.

@Carl
I checked again and my PC is connected at 1.0Gbps and so is my Nvidia Shield, both connected to ETH on different decos on the same floor. I did change from "Auto Negotioation" to "1.0 Gbps Full Duplex" on my lan-adapter and did a reboot but the file transfer speed still maxes out at 11-12mb/s when transfering a file client to client.

Have you tried different types of files.
For example, a folder with 10,000 small files will be slower then one file that is 4 GB (movie).
Are the two computers on the same Deco or are they wired to different units?

The files i'm transfering are +4gb in size. When i tried connecting my laptop to the same deco as my PC running the FTP i get speeds to 30-40mb/s which is great improvement but still a bit slow it youre going to transfer 4TB of data.
Not really sure where the problem is. What dataspeeds are people getting when transfering data from one client to another?

Ok. I still haven't solved this so im adding a simple sketch of my network.
If anyone could test doing a file transfer between 2 clients connected on ETH (cat5 cable) to 2 different slave decos and post the results it would be great help.
I did try and connect my PC to the same DECO as my Nvidia Shield and the data transfer speed hits 500mbit. When connected to different slave decos it drops to 100mbit.

To rule out the possibility of distance between the two Decos as being the culprit have both been moved close to each other (same room) and tested?

@johsam Im having same speeds as you describe with only DECO M4R (v2).
@Tony @Carl could you please give a look to my very similar scenario, but with a single Deco unit
Layout 1:
PC --(eth/Giga)-- SWITCH --(eth/Giga)-- DECO ---(wifi/867mbps)--- Macbook
When copying a large file, I get 14MB/s
But, if I connetc the MAcbook to the Deco eth.
Layout 2:
PC --(eth/Giga)-- SWITCH --(eth/Giga)-- DECO ---(eth/Giga)--- Macbook
I get ~50MB/s (using both eth ports on the DECO, no wifi)
So I think something is degrading a lot when converting from ETH to WIFI.
As you can see, in my test Im using only 1 Deco and get those 14MB/s (~112mbps) when in Wifi even though the link speed is 867mbps.
Hopefully this is some software related issue TP-LINK can fix in a comming firmware upgrade.
The worst case scenario is that this product is somehow limited at hardware level and is not good for a single client trying to get the moset bandwith possible.
Note: I use DECO in AP mode, no QoS

Good (for me, not for you ofc) to finally see someone that has the same problem. I have tried everything, swapped cables, moved the Decos around but i end up with the same numbers.
It would be nice if someone in the staff could make a similar network setup and test the data transfer speed and post the resaults here.

What was used when doing the transfer? FTP? Samba?
Are you able to do an iperf3 speed test? (free software to measure LAN speeds).

Sure thing. I ran this on my android-phone with my PC as server. Phone on WIFI ofc. PC on eth connected to a DECO.
** edit. My android tv-box uses SMB. But I'm getting the same speed when using FTP on another PC connected to the same network
