Model: Deco XE75  
Hardware Version: V1
Firmware Version: 1.2.9 Build 20240724 Rel. 39578

I recently purchased and began setting up the TP-Link Deco AXE5400 Tri-Band WiFi 6E Mesh System (Deco XE75) with three separate Wi-Fi networks: a standard network, a guest network, and an IoT network.

 

I'm facing an issue where devices on my standard network cannot communicate with devices on the guest or IoT networks. Specifically:

 

- I cannot print from my laptop (connected to the standard network) to a printer that needs to be connected to the guest network.

- I cannot cast music from my phone (standard network) to a Google Home Mini on the IoT network.

 

I would like to configure my router to allow devices on the standard network to access specific devices on the guest and IoT networks, while maintaining the security benefits of network segmentation.

 

Could you provide guidance on how to set up inter-VLAN routing or adjust firewall settings or do some kind of thing to allow this cross-network communication? Thank you in advance!

I despise VLANs because that seems to be their function, to segregate/isolate networks. I'm afraid if you need access to a printer it should be on the main network, as well as all devices that need to print. Similar with your casting phone. The guests who don't need to print would be on the guest network and IoTs such as lights on the IoT network....

I suggest reading this: https://community.tp-link.com/us/home/kb/detail/412694

 

The isolation is always bidirectional.
