@sarkersujan786 It doesn’t work on the BE65 either when running the 1.3.2 firmware.

  @Solla-topee  Luckily its very easy to setup speed limit. 

Here is the following asnwer for you question.

  1. What device have you configured the speed limit for? What download and upload speeds did you set? What are the actual download and upload speeds of the device? 

-I try and set speed limite to like 10 different device, like, Phones, Laptop, some are connected wired. No device is working under speed limite. I notice my macbook worked once but then it dosnt.

  2. How do you test speed on the device? For example, is it connected to the Deco via cable or Wi-Fi? On which website do you test the speed?

I can see the speed uses real time on the deco apps and im try browsing on my mac and phone and on my mac has network speed shown apps.

  3. If your device has enabled a random MAC address/private MAC address, please disable it, ensure the device has the same MAC address you set the speed limit for, then check if the speed limit feature works.

I don't know about this feature and some of device are my neighbors that i cant touch there device. is there any way to set fixed mac on my tplink deco and it wont give troble to the neighbors in future?

here are attachet screenshot...

  @WelshPaul  then why the add this feature and how to slove this?
