Very slow Deco M9 Plus Wifi speed
Hello,
To upgrade my Wifi network at home, I bought 3 set of Deco M9 last week. After the setup, I had significant upload/download speed increase in my home network which is 500M/500 network. The upalod/download speed are devices are about 300-400M across all rooms, which meet my expectation.
However, after using that for 2-3 days, the Wifi speed has got worse a lot on my Wifi connected devices. The results are shown in the following pictures
As shown above, the speed within the Deco Apps looks OK. However, if I use Speedtest on the same iPhone on the same location , the result is as below,
But if I go to the master Deco, the speed is OK as below,
And sometimes in testing the Wifi speed, Speedtest can not finish the upload testing and gave an error message to ask me to check my network connection even though the Wifi signal indication on the screen is full. The download testing works fine.
About the product information, I do not know where to find the Hardware version so I just input the most updated one as it is very new product for me.
All these things happened on the Wifi connected iPhone, my hardwired connect laptop works fine.
Please help!
Thank you
Peter
