Model: TL-WPA8631P KIT  
Hardware Version: V3
Firmware Version: 220330

I have a TL-WPA8631P Kit, with TL-PA8010P connected to Draytek 2865Lac router, and TL-WPA8631P v.3.0 at far end (approx 15m away) of old stone-built house. Draytek router is using EE 4G connection via external antenna. All speed tests below done via web browser at, using same Windows laptop and cables, and repeated at least 6 times each.

1. Ethernet cable to router - 68Mbps download, 28Mbps upload.

2. Wi-fi to Draytek router (using 5Ghz band) - 35Mbps download, 20Mbps upload.

3. Ethernet cable to TL-WPA8631P - 65Mbps download, 25Mbps upload  

4. 5Ghz wi-fi (with 2.4Ghz turned off) to TL-WPA8631P - 8Mbps download, 16Mbps upload

5. 2.4Ghz wi-fi (with 5Ghz turned off) to TL-WPA8631P - 4Mbps download, 14Mbps upload

Things tried so far:- upgraded TL-WPA8631P firmware to latest version (V3_220330) - no difference. Moved TL-WPA8631P to different sockets around the house - no change. Tried different wi-fi mode settings - no change. Have a second TL-WPA8631P unit which tests out exactly the same, suggesting there's a fundamental problem with the wi-fi on these units.
Has anyone had better wi-fi download speeds from these units? If so, what did you do?

 Thanks for your information, if powerline devices wired speed is good, only Wireless speed is not as expected, you could try the following troubleshooting steps:
1.Log in to the Web page of powerline device and go to Wireless-> Settings-> Advanced-> Channel/Channel width
Try a different channel for 2.4Ghz, and change the channel width to 40Mhz.
For dual-band powerline device, try a different channel for 5Ghz and change channel width to 80Mhz

2. Try a different network device to test speed, like a mobile phone different PC 

 If end-devices supports 5GHz, connect to 5GHz to check speed since it is faster.

Note: when test wifi speed only run speed test on a single network device and turn off other network activites if possible ]

If still the same, can you share aphoto of the Wifi speed and Wifi Link speed on the device, and a photo of Wired speed when connected 
 How many end-devices connected to powerline devices and what are they, like pc, laptop or smartphone, Windows or mac? Do all the devices have the slow speed issue?
