@David-TP 

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.

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.

  @David-TP So after all of these beta releases and still no network or clients isolation for the IoT network??! How long do we have to wait before we can stop using the guest network for IoT devices?

Really happy to see that DoH & DoT is being added. I'm a new BE65 owner and was surprised to find these key features were missing. I found the KB from 2024 for an older Deco model and so assumed assumed a newer, high end system would have the same.

In my setup I have some IoT which need to communicate with my Apple TV (HomeKit/Matter Hub) which sits on the main network. So total isolation wouldn't work for me. For these the ideal would be some NAC rules to provide limited access between the IoT network and the hub.

I believe you can isolate any specific client, so that works for IoT devices which only need Internet access.

  @David-TP Wish there's more option with Device isolation, like isolation group 1, group 2 etc. I have different type of devices which i would like to be isolated from each other.

@David-TP So my Deco BE65v2's just crashed again. I turned on an Apple TV that connects via Wi-Fi and started to browse the app store when all three Wi-Fi networks died. Devices connected via Ethernet wouldn't work either. LEDs remained solid green. This time I just left everything alone and eventually Ethernet started working again, followed by Wi-Fi.

I have submitted my logs as requested in a previous post.

Addition 17/03/2026:

Oddly enough, just logged in to the Deck to view the logs and it's only showing logs for today's date. I haven't rebooted the the devices and they haven't at any point been removed from their power source.
