Hi David 

Yesterday late in the evening I had to restart the system twice more because some IoT devices (eWeLink roller shutter switches) would not connect to the network. This problem had occasionally occurred before (even with the official firmware), but this time the situation was that in the TP-Link Deco app the switch appeared as connected and had its own IP address, while in the eWeLink app it was unavailable, and the LEDs on the device were blinking, which physically confirmed the lack of connection.
Interestingly, after those two additional restarts the switches connected, and access to the main Deco via IP and domain was also restored.
At the moment everything is working, but something must be wrong with the software if this type of issue occurs.

Thank you again for your help, and for now it seems that support from the engineers will not be necessary at this stage.

  @David-TP Hello again,

 I am testing the new firmware and noticed some unusual behavior (I didn't test the previous firmware to compare the same issue). The wireless data exchange between clients doesn't appear in the Deco app or the local web interface. Also, as you can see in the screenshots below, the data transfer between the smartphone and PC (even though both devices use the 6GHz band and are about 1 meter away from the Deco B63, the speed is only around 35 MiB/s ≈ 308 Mbps). I tested the speed with MLO activated and immediately after a network optimization. 

Deco web

Win11

I did retest copying the same file, but changed the direction, and it shows deffrent performance as below:

Android (16) --> PC Win11  308Mbps

PC Win11 --> Android (16)  1200Mbps

so in brief:

- Data exchange between wifi clients doesnt appear in the Deco app or web interface (only internet traffic is there, I guess) and data exchange between clients doesnt appear to be affected by the speed limit, thanks God :).

- Network performance is behaivng deffrently when change the direction.
