In general with all mesh equipment it is critical to provision and test hardware indoors on a table before installing it. Particularly since access to installed equipment at height often requires ladders, lifts or other equipment as well as safety procedures.
You are missing "wds auto" under the dot11radio profile. This is necessary for the mesh to come up.
You also did not specify a channel list for operation, this is highly recommended to set statically after completing a spectrum survey to see which channels are clear. MeshOS has limited ability to sense channel conditions but it is not a spectrum analyzer. You need to do that in advance.
How long is the link? If more than 500 meters then you must also set the distance parameter.
"mode gateway" is only on the wired link of the portal side. Do not specify this on the other side or set "mode access". This command tells the OS which direction is north in the link. Also, it causes AWR to propagate any routes down to the other nodes in the mesh.
