Model: Archer AX73  
Hardware Version: V1
Firmware Version: 1.0.4 Build 20210717

I am experiencing slow SMB file transfers between two computers with Intel AX200 cards.
 

Both devices have a stable connection of 1201mbps with the router and individually reach more than 700mbps of internet speed per speedtest.

 

However, when transferring between both computers, the transfer rate remains between 13-17MB/s.

 

The AX73 router is a new device and it comes to replace an AX10 that worked without problems and in which it reached transfers of up to 40MB/s between the same two devices.

 

By connecting one of the devices directly to Ethernet I can achieve transfer speeds of even more than 100MB/s. I expected to achieve approximately the same connection speed using WiFi with this new device, or at least faster than the previous router, considering that its theoretical speeds are 4 times higher than the AX10.

How do you transfer files between the two computers? Is there a USB device plugged into the USB port of the AX73?

 

Or you just share the file over Wi-Fi, do you use any software to help with the transfer?

Hi @Kevin_Z 

 

I transfer files between shared folders on 2 Windows PCs. One PC I use as a file server, HTPC and plex server, the other is a laptop.

 

Capture with the transfer rate obtained using WiFi.

 

 

I also tested the transfer speed by connecting a portable HDD to the AX73 and I got about 40-45MB/s read and over 20MB write with the 2 PCs over WiFi, which is in line with other users' reports.

 

WiFi properties in HTPC

 

WiFi properties in Laptop

 

Current WiFi configuration with separated SSID for 2.4GHz and 5GHz

I just ran a new test, this time I ran a transfer from the USB drive on the AX73 to the HTPC (one 4GB file) and simultaneously ran a Speedtest on the laptop. Obtaining a large decrease in speed when running the upload test. 75 mbps instead of over 400 mbps

 

 

I would like to know if this is a normal behavior or if there is something that could be affecting the speeds when one computer on the network uploads while another download.

 

I no longer have the AX10 that I used to use but knowing that the transfers between computers were around 40MB / s makes me think that there is some problem that could be reviewed for a next firmware update.

I honestly cannot tell you whether this is normal or not when transferring between two devices in the LAN over Wi-Fi, but we will try to find it out with the support engineers, please check your email and confirm.

I also find this problems. 

I had changed c2300 to ax73,and usb sharing speed (50 r/w)  dropped to (45/20 r/w). 

when I use lan cable ,it has 90/60

Hello, I want to know if OFDMA is enabled or disabled on the AX73? Try disabling OFDMA, then reboot the router and reconnect to the Wi-Fi network to confirm if the transfer speed will be better. OFDMA is generally designed to allow simultaneous low-data-rate transmission from several users, we can see if it affects the high transfer in the network.

@Kevin_Z 

Thank you for reply.

I have tried as you said (disable and reboot),and nothing changed.

I also tried twt, zero wait dfs,wmm,nat,upnp...etc before

Another thing, when I turned off  dlna in tplink usb setting, the LAN cable connections also droped to 55/30.

I think It shouldn't be slower than wifi5 archer c2300

I used wifi6 5ghz 160mhz , and it shows 1200/1200 wifi speed in win10. It's no different with lan at fast or speedtest

I think it should be at least 70/50 with wifi 5ghz, but it only has 50/20, and sometimes 50 dropped to 5~10 in 2~3 second.
