Hardware Version:
Firmware Version: 1.4.3

Much like the old thread, https://community.tp-link.com/us/home/forum/topic/152513, I'm getting solid 350+Mbps on a speed test from the Deco app but ~125Mbps to any devices.

The firmware is up to date.

I've tested devices:

* Ethernet connected to the main Deco

* Wifi connected within a foot of the main Deco

* Wifi connected to the main Deco with 2.4GHz turned off

 

All tests return very reliable ~125Mbps.

@Carl 

Thank you for your help and pointing to the chat.

 

The solution was to turn off the QoS settings.

What mode are you using the Deco in?  Also is the Deco acting as the router or just as a wired and wireless AP?

The Deco is a wifi router.

Mesh mode is on but my tests are from the unit pluged directly into the cable modem. I've tried turning off mesh as well.

Have you ran a speed test from the main unit via the Deco App?  What were the results?  When you test on your device are you using the same test server?

When I run the test from the app to get the speed that the router is seeing through the modem, I get 300-350Mbps.

When I run the speed test from anything going through the router (wired or wireless) to the same speed test site, I get ~125Mbps.

Are the device test from the main Deco or the remote ones?

I've added highlighting to the original post as it's answered your recent questions. Is there a way to chat directly without posting on the forum and waiting for a response?

I've tried these tests with and without a second Deco in mesh. All speed tests are consistent at ~125Mbps.

Chat support is available through our website. I will forward this additional information to our testing team, however please let me know if you prefer to contact the chat support team as I would want to avoid two teams doing the same work.

Good to know.  in my experiance QOS typically only affected wireless devices and to the remote nodes so its good to know for future.
