Hi, welcome to the community.

Currently, the IOT network is not isolated from the main network and they are still accessible to each other. 

As for the connection preference, did most of the devices behave like this? Can you share some models?

By the way, are they connected to the main network or the IOT network?

If possible, could you please refer to this link to help me submit the APP log:

Thank you very much.

Wait for your reply.

Hi, Thanks for getting back to me.

I have checked with the engineers before about the further improvement of the IOT network, but so far there hasn't been an update.

I will confirm with them again since there are several similar inquiries in the past few weeks. If there is any news, I would update it on the community.

As for the connection preference issue, I would forward the case to the engineers and could you please refer to the previous reply to help me submit the APP log?

Thank you again.

Best regards.
