I have a building that has 4 floors with multiple access points per floor for coverage. The problem that I am having is that a user on the 4th floor for example with authenticate and connect to an AP on the 1st floor, even though there is an access point about 20 feet away from the computer.
If there are 4 access points within reach of a specific user, I see the logs in IAS where they continually connect to all of them instead of staying connected to a single radio. These users are not roaming either, they are stationary.
