My new configuration has been running for a while now:

I replaced the AX10 with an AX73 because the AX10 doesn't support Ethernet backhaul. I've disabled Smart Connect again.

Overall, it seems to be working reasonably well now.

There are still the following issues:

- Some Smart WiFi switches go offline sporadically and need to be reconnected, even when they are near a mesh node.

- Commands to Smart WiFi switches are sporadically lost. (It could also be because the Wi-Fi switches are cloud-based.)

- The WiFi camera image often stutters or freezes briefly, despite being close to a mesh node and using a low resolution.

- Mobile phones often remain stuck on the 2.4GHz network, even when the signal is weak, instead of switching to 5GHz. This is probably because Smart Connect is disabled.

Thank you.

Update

Four Smart WiFi switches went offline again in a short period of time.

I checked with the Net Analyzer app and found that the 2.4GHz network keeps dropping out, despite a high signal level; the 5GHz network is stable. I'm starting to suspect that the Easy Mesh system isn't fully developed yet.

I'm considering removing one of the three nodes from the mesh and setting it up as an access point with the same SSID and password.

Is there any reason not to do that?

Thanks for the feedback.

1.
I updated the firmware on the two AX73 routers. The result was that the 2.4GHz network became even worse.

2.
I then reconfigured the bandwidth of the 2.4GHz network from 40/20MHz to 20MHz. It seemed that the 2.4GHz signal didn't fluctuate as much afterward. But the quality was still very poor.

3.
Now I've performed a ping test on all three routers at a distance of about 1-2 meters on both 2.4GHz and 5GHz:

Router                                         Overall Quality
------------------------------------------------------------------------------------
Salon - AX55 - 2.4GHz                  90%

Salon - AX55 - 5GHz                     96%

Pump Room - AX73 - 2.4GHz       12% !!

PumpRoom - AX73 - 5GHz           97%

Solarhaus - AX73 - 2.4GHz             9% !!

Solarhaus - AX73 - 5GHz               82%

This means that the AX73 routers have a major problem with the 2.4GHz network!!

What now?

Update

The 2.4GHz network is consistently performing very poorly.

Today I disconnected the AX73 node in the solar house from the Easy Mesh and configured it as an access point (AP) with the same SSID and password.

The 2.4GHz network in the solar house now seems to be working stably.

The ping test on the 2.4GHz network now shows an overall quality of 95%, up from 9% previously.

The two cameras connected to this network are streaming much better.

Interestingly, the ping test on the AX73 in the Pump Room on the - 2.4GHz network now shows about 50% overall quality, whereas previously it was only 12%.

My conclusion:

The AX73 works as a standalone device, even on the 2.4GHz network, but not in Easy Mesh.

  @Kevin_Z 

I think that makes sense. It should be easy to reproduce.

Thanks.
