Hi, I have already replaced the two APs with the 225 outdoor ones, working in mesh mode between the two APs.
The connection status can be seen from the images, but I have removed them because the tplink technicians advised me against setting up this configuration as it is a mesh for an aerial connection. I must say that everything worked, but I did as I was told, even if I was not very convinced because to achieve this, the two APs were wired but communicated at 5 ghz via mesh.

hello Vincent, I returned them because as I had previously written I had managed to make them work even if the signal obtained at ghz was -83 DB so low. Despite this everything worked, only that I followed the opinion of the support.

  @Vincent-TP Thank you. But as I had written I returned them so I can no longer try. The reason why I made them what I had written, that is, not recommended by the technicians. But I ask you if in your opinion, this configuration was good or not.
