We have two units next to each other within a building, all APs in the same group, all AP315's. In one half of the unit, my device will connect at a minimum of 180mbps and has maxed at about 250. In the other half, I struggle to get beyond 85mbps. I have even been the only client on an AP, connected ov 5ghz, 80mhz is disabled.
Whilst I appreciate there could a lot of variables at play, there does seem to be a distinct issue, as soon as I enter the other unit, my speed more than doubles!
Perhaps theres some sort of interference, this is my next investigation.. just wondered if there was antyhing else to consider? Especially when I can be the only client on an AP, im still heavily restricted!
