Hi,

I recently purchased a AC 1300 Archer T3U.

I installed the drivers and it worked right away. The issue is that I am capped at 200MPS.

I am using windows 10 pro
Modem speed is at 1000Mbps / Fibe.
It has 5Ghz mode.
using usb 3.1 ports
wireless mode is on : 802.11ac

When I check on the reception speed on the wifi properties it does show I get 866 Mbps.

But whenever I am doing a speed test online with https://www.speedtest.net/ for example , it is capped at 200Mbps.

A bit confused here, isn't it supposed to show the same information

Why I am not getting the full Mbits / s when I make a test online ?

Am I missing something here ?

@Riodgn

The interface of Archer T3U is USB 3.0, it is recommended to try a USB 3.0 port on the computer if possible. It looks like the adapter and computer synchronize at USB 2.0 and speed is capped around 200Mbps.

Here are some other suggestions for you:

- Log in router and try a different 5Ghz channel like 36/40/44/48 etc. and set 5Ghz channel width at 80Mhz.

- Disable the built-in adapter when use T3U

- Try this latest chipset driver for and see if help with the issue:

Here is the instruction to manually install driver:

If still the same case, may I have a photo of the speed on other device at the same location?

What is the model of router, and can you please share a photo of router's wireless settings?

May I know the model of your computer, please help check the driver version of adapter and computer motherboard info and send us the photos: https://www.tp-link.com/support/faq/2722/
