Seeking information of how to best diagnosis this 3rd AP not having the speeds the other two have. AP also seems to restart often. We have checked the 100V feed for dropping or dirty power. All check great.
More details are needed to understand the performance issues in mesh.
1- What controller is managing these APs? 2- What is the software version? 3- Distance between Root and Mesh AP. 4- Type of environment where APs are installed. 5- Third AP is connected to root AP directly or there are more than 1 mesh hops?
Please note that running a AP in mesh mode will give you half throughput than what you get from root APs. By adding additional hops, throughput will decrease by half from its last hop.
