I have 8 dorm buildings that I provide with wireless access. Many of the students have started complaining about poor performance and disconnects in the last month or so. When I view the Wireless Status Summary on any of the Access points, they all report "High tx error" on both wifi interfaces. This includes a few AP120s that service other dorm buildings (smaller ones, only 1 per building, not on the attached map).
I am using AP120 access points and HiveManager Express. I have attached an image of dorm buildings with a rough floorplan. Each building has 2 AP120 access points, with the exception of one of the buildings, which uses a product from a different vendor. I have not done any tweaking of radio settings or anything of that nature, hoping that the auto settings would be sufficient.
I do have a wireless bridge that intersects the top 3 dorm buildings in the map, that runs in 5GHz spectrum.
Any suggestions would be greatly appreciated. I can provide more information if needed.
