Hello @MarcinJ ,

The latest firmware, 1.4.3 Build 20250813 rel.63911, adds support for guest network mesh Wi-Fi for the AX55 Pro v1. However, please note that guest network expansion can only be achieved when both the main router and satellite router support this feature.
The Archer AX73 you mentioned does not currently support mesh Wi-Fi for guest networks.

Hello! I want to inform everyone who wants to repeat my actions to create a home network 2.5 Gbit\s that it works great in this configuration. Good luck!

  @Кевин_З Hello! I have read all the pages of the conference and I have a question for you: I use Archer AX72 Pro v1.0 1.3.1 Build 20240426 rel.40133(4555) as the main router, I use the WAN/LAN 2.5 Gb/c port to connect the slave router, the slave router is Archer C80 v.1 1.13.15 Build 240812 Rel.53634n(4555), the network operates in EasyMesh with ethernet backhaul mode. The routers are connected by a 10 m long category 6 cable. I am going to buy and install a SWITCH TP-LINK TL-SG105-M2 next to the slave router, connect the network cable from the main router to the switch (it provides connections at a speed of 2.5 Gbps), and connect the slave router Archer C80 to one of the ports of the SWITCH TP-LINK TL-SG105-M2. Do you think that connecting the SWITCH TP-LINK TL-SG105-M2 will not disrupt the operation of EasyMesh with ethernet backhaul? Best regards, Alexander

@AleksandrP2 I'm happy to hear it's working great in your network. Congratulations!

  @Kevin_Z hey there! curious if the new EX521 has this ability or not, I was not able to find any information. I'd like to use it as a satellite with a XX530V V2. Thanks!

@matheusrosin 

Yes. EX521 does support EasyMesh Ethernet Backhaul by default.

Hello, @Kevin_Z, TP-Link development team and community,

 

I am writing from Brazil to commend you on the continuous improvements to the EasyMesh technology, especially the Ethernet Backhaul feature, which is extremely useful. I would like to report a specific behavior I have observed and suggest an improvement for future firmware versions.

 

Background and Scenario:

 

In Brazil, local regulations permit the use of channel 13 on the 2.4 GHz frequency. In the area where I live, there is a large number of neighboring Wi-Fi networks, and the vast majority operate on channels 1, 6, and 11. Channel 13 is rarely used, making it ideal for obtaining a cleaner, interference-free signal. 

 

With this in mind, I have configured my main router, an Archer C80, to operate on channel 13.

 

The Identified Issue:

 

I have observed that when using the EasyMesh network with Ethernet Backhaul, the satellite routers (three Archer C64 units) do not follow the main router's configuration. While the Archer C80 correctly broadcasts on channel 13, the Archer C64s, which are connected via wired backhaul, automatically operate on channel 11.

 

Interestingly, I ran a test: when I disable the Ethernet Backhaul and create a purely Wi-Fi-based EasyMesh network, the satellite routers and extenders respect the main router's setting and all operate correctly on channel 13, as expected. The issue seems to be specific to the wired backhaul implementation.

 

My Setup:

 

• Main Router: 1x Archer C80 (Hardware Version V2.20)
• Satellite Routers (via Ethernet Backhaul): 3x Archer C64 (Hardware Version V1)
• Extenders (via Wi-Fi): 2x RE200 (Hardware Version V5)
• Firmware: All devices are updated to the latest firmware version available on the official TP-Link website.
• Compatibility: All devices are EasyMesh compatible.

 

Request to the Developers:

 

I kindly request that the TP-Link development team investigate this issue. The ability to set a specific channel on the main router and have all network nodes—especially those connected via Ethernet Backhaul—adhere to that setting is crucial for optimizing network performance in environments with high Wi-Fi density.

 

Fixing this behavior would allow users in regions like mine to take full advantage of less congested channels, such as channel 13, resulting in a more stable and robust connection for the entire mesh system.

 

Thank you very much for your attention and for your excellent work in developing these products. I am confident that this improvement would benefit many users of the EasyMesh platform.

 

Sincerely,
Fernando Cardoso

@fernandocardoso Thank you very much for your detailed description of the unintended behavior you experienced with the EasyMesh Ethernet Backhaul.

Could you please send us the configuration file for your Archer C80 via email at support.forum@tp-link.com, and we will investigate it further?
