Hi,

Since you have firmware version 1.3.1 installed, you should be able to log into the Satellite Easymesh Archer AX55 via its IP address.

So, could you please check inside the webGUI of the "Salon" AX55 whether it shows any clients connected?

Hey @woozle , thanks for your reply!

It is showing only 1 client connected, even if it really has numerous ones connected.

It was only showing up my phone, I connected my Mac laptop too and started showing up only the laptop, and the phone now is not listed in any of the routers. Same thing goes for 2 Tapo C425 cameras, one Tapo P100M, one Tapo CP300, one Tapo H100, various smart light bulbs from other manufacturers and a bunch of smart home appliances (air conditioning, smart oven, smart diswhasher, etc), they are connected but they don't show up in any of the routers.

Disconnected the laptop again, and only the phone showed up instead. Disconnected the phone, and now it's only showing up the oven. Connected the laptop again and it showed up instead. All these devices are connected using the 5GHz network, I connected a new 2.4GHz device (smart bulb) and it didn't replace the device that was being shown, so I assume it is only displaying the latest connected device, but prioritizing the 5GHz devices.

I hope this helps.

Thanks!

Sorry, forgot to attach the screenshot of the satellite router's client list:

That looks like a bug in the firmware then. TP-Link should verify this.

The satellite router is also messing with my ISP router somehow, making it randomly restart. When it happens, the ISP router keeps restarting itself non stop and I have to unplug the network cable going to the satellite router to make it stable, otherwise I lose the internet connectivity completely due to the continuous restarts.

After unplugging the network cable, the EasyMesh connection between the routers was stabilshed using WiFi backhaul instead of Ethernet backhaul. Now, all the devices are properly listed in the router's admin webpage and in the Tether app. So it definitely looks like an issue with the Ethernet Backhaul.

However, the satellite router's admin page keeps showing only one connected 5GHz device, like in my previous screenshot.

I have a very similar setup with two AX55 routers.  The only difference is that the ISP router and the main router are on the second floor with the ISP router in bridge mode.  The satellite AX55 is on the ground floor and is directly wired to the main router with no switches in between.  Some users have reported problems when using the ethernet backhaul connection through a switch.

The clients list in the satellite router never shows all its connected clients.  For example, only one client is now showing in my router's web interface but 10 clients are connected.  I brought this issue up a short time ago and the thread is here.  The good thing though is that the main router's clients list is very complete and shows all the clients, independently of which router is providing the connection.  If you need to see an accurate list for the satellite router, you need to go to Advanced, EasyMesh, Mesh Device Detail, and click the edit icon (the one on the left of the three).  In the new window, click Clients.

I would recommend that you connect your ground floor AX55 directly to your ISP's router and make it the main router for EasyMesh.  If double NAT is a problem, you can configure it as an Access Point instead of a wireless router.  It still can act as the EasyMesh controller. The AX55 on the second floor should be connected with the cable between the ground floor and second floor.  I had this setup earlier this year due to beta firmware problems.  I also have gone one step further by placing a range extender (RE700X) on the first floor.
