MT6000/ Flint 2 firmware 4.9.1 IoT support

Router

What’s the point adding IoT support if any AP connetced to the router won’t re-distribute this IoT network?

I have 2nd Flint2 device connected with LAN and 2nd router is not propagating any IoT network that is setup on 1st device. Why IoT cannot be distributed by AP?

Hi,

The IoT network created on the main Flint 2 is a separate network from the Main LAN. When the second Flint 2 is connected in AP mode through a normal Ethernet connection, it will not automatically inherit and extend the IoT network configured on the main router.

If you want the second Flint 2 to provide the same Main / Guest / IoT networks while keeping them separated, VLANs are required to distinguish these networks over the Ethernet connection between the two devices. The connection between the two routers needs to carry the corresponding VLANs, and the VLANs can then be mapped to the appropriate SSIDs on the second Flint 2.

If this is what you would like to achieve, you can refer to the following example from another model/firmware version with similar requirements:

Thank you for your support and understanding.

Thanks. I have asked ChatGPT to deliver me final status and he directed me line by line on the cofiguration , with checkpoints. All is completed. That was effective, as it was providing exact commands that should be entered in SSH Terminal.

The Main router is the only device doing routing, DHCP and firewalling:

  • Main: 192.168.50.0/24

  • IoT: 192.168.107.0/24

  • Guest: 192.168.9.0/24

The AP is only bridging Wi-Fi clients into the appropriate VLAN/network.

DHCP for IoT and Guest comes from the Main router through the tagged VLANs.

I tested both VLANs end-to-end:

  • IoT client connected to the AP receives a 192.168.107.x address and Internet access.

  • Guest client connected to the AP receives a 192.168.9.x address and Internet access.

  • Guest clients are isolated from Main and IoT by the firewall on the Main router.
