I hope someone can help me with this, I have contacted TP-LINK about this, but they can’t reproduce this strange thing.

When I turn on mesh on site all mesh access point go from 80mhz to 40mhz bandwidth, connection speed goes from 866 to 400mbps and from 433 to 200 mbps,

if I turn off the mesh, all access points are back on 80MHz bandwidth again.

It’s not necessary to enable a mesh link, I have tested with only one access point in a site and the same happened.

It happened only if I use 80MHz Bandwidth on access point, if I use 20/40/80MHz bandwidth it takes a couple of days before access point switch to 40MHz Bandwidth.

With this configuration switch access point immediately to 40MHz bandwidth when mesh is enabled.

Channel must be static not auto and it's happen on all channel, bandwidth settings are important to set to 80MHz.

Restart access point after changing settings.

I use WiFi Overview 360 pro on my android phone, and I can see channel with and much more in this app.

I can’t see anything on access point, I see it only on client with wifi overview or client speed on controller. As you can se the access point is 80Mhz bandwidth her.

Mesh is OFF

Mesh is ON it switch to 40MHz

The only thing I do is enable or disable mesh on site like this, nothing more.

I use EAP225-Outdoor and OC200 with latest software, I install a brand-new software controller ver. 3.2.7 on a windows computer to test, but it was the same. I have tried original POE adapter to bypass POE in switch but no difference.

Is there anybody that have same problem or maybe a solution to fix this?
