@dahls try restart everything

@Fae here is a similar case of clients disappearing.

@Fae For your information wireless client view gradually disappears to finally show 0, restart controller and everyone is back in the view, this has happened 5-6 times since I upgraded.

@BahamasTech create wlan groups and assign groups to the different access points

@guyd2 it says nothing about cable length on the cable that doesn't work, but regardless, there is a fault between the switch and the access point. there is no doubt about that. so I suggest you...

@MR.S I missed that you have already tested with a short cable. sorry :-) how long is the cable from the switch to the access point?
