    Hi

    Seems that something is affecting my wifi mesh 5GHZ backhaul as it keeps reverting to 2.4GZ because some kind of interference.

    I used an EMF to capture the issue (few hours) . Not 100% sure what the data means, anything that can point me on the right direction?

    Didn’t see anything remarkable in that. Did I miss something?

    Why do you think it’s external interference rather than a defect or power limitation within the equipment itself?

    Is there something remarkable about the enviroment you are in?

    The setup is a WIFI Orbi Mesh. 3 devices. Two of them are fine. Only the one in the play room is having the issue. I moved this device upstairs and it kept the 5GHZ connection. There is something in the playroom / kitchen which is interfering with the connection to the satellite in the living room. (Living Room-Kitchen-Playroom layout )

    It is not a mesh device fault as the other satellite which is in the garden and more far away than the one in the playroom is working fine. I also swapped the two, same issue.

    Understand - it’s still more likely to a power/transmission/obstruction issue than such a degree of external interference in a domestic dwelling.

    I have the google mesh system, and had to play around quite a bit with the location of the units to get them all integrating correctly.

    Have you moved this device?

    I would check if there is any interference from a microwave oven if you have one is in proximity. Possibility of spurious/ harmonics

    Did more test and it seems that the Electromagnetic field values from the EMF reader get high when going close (10-20 CM) to the wall where the mesh was placed. That high reading doesn't happen in any other wall in the house. there is only one socket on that wall. Even with nothing connected. I moved the mesh on the other side of the room and it has been an improvement. What could cause these high readings? Any potential safety issues?
