Hey, thanks for advice but i think you dont read my whole msg :)

The main problem is:

AX80 EU in lastes firmware Its not working adding easymesh via WiFi becouse while adding device progress come to 100% and its fail to add statelite device (AX55). No matters how mamy times i do factory reset on all devices.

Also I alreday said on my topic i found solutions to add statelite devices by connect via Ethernet backhoul and that works flawess. With not problem I adding satellite device in easymesh by that option.

But Second problem is when easymesh satelite devices alreday added and i want them working by WiFi no by Ethernet cable. 

When i disconnect ethernet cable, satellite devices (2xAX55) connect via WiFi to Main router (AX80 EU). But main router show them offline anyway . Becouse of that i cant control easymesh sattelites devices via Tether app or AX80 webpage.

Available firmwares on the TP-Link page It depends on which country you choose.

Example: On the Italian TP-Link page, it shows the last firmware from 2023 for AX55v1, but in Canada, from 2025.

From my experience, each country webpage department is too lazy to update every new available firmware.

You need to ask them to do it or find out alone which country has the newest one.

I talked before with TP-LINK engineers, and AX55v1 hardware is the same everywhere, no matter from which country firmware you download.

( but better always ask them to be sure if you have other model)

But AX80v1 hardware is different for EUROPE (built-in antennas) and the USA/CANADA (outside antennas).

So if hardware is different, that means firmware is too, probably. :)

Thank you again for the advice, but unfortunately that won't fix anything. It's buggy firmware on AX80v1, and they need to fix it ^^. That's why I report it.

Also, AX80v1 has gaps in firmware features, and TP-LINK needs to update it too.

BTW.

In my home network, I have BE800v1 (main) and 2x BE550v1 (satellites), :D and I used only beta firmware provided from TP-Link engineers. It works better than all the official firmware. LOL. 

Hello  @Joseph-TP  thank you for answer :)

I mean, I can't add a satellite device via EasyMesh Wireless Backhaul—it's an error! every time and popup window to contact with support. 

But add EasyMesh satellite via Ethernet backhaul , work like a charm with no probelms/

"But if you unplug the Archer AX55 from Archer AX80's LAN port, it will turn offline on the device info page even it is still running network, right?"

Yes indeed.

- The network is running after unplugging cables. (when i add them via Ethernet backhaul)

- I'm able to log in to the webpage of satellites (AX55), so it's connected to the AX80.

The AX80 shows Easymesh satellites offline, and because of that, I can't control them via the main router webpage or Tether app. 

Of course I do restart; I do factory resets a couple of times, still the same issue.

Also, every firmware and Tether app is up to date. At least I don't find newer firmware's on the TP-Link page. 

And it will be nice if AX80 gets some new features like the AX55 router.

Example: To be able to bind capabilities for satellites and clients under EasyMesh.

BTW. @Joseph-TP  remember its AX80 version with internal antennas ^^
