Hi Joseph,
I was hoping you responded!
I have read many of your post and was currently reading a revious post of yours around a similar problem and your suggestion of lowering Power.
So what I did was , where the device is evenly located between two Access points I created a group and lowered the power settings to 9-11 on the 2.4 as these devices are only 2.4ghz compatable. and then moved one Ap of the two into the new group.
All other Aps are set to 21 on 2.4ghz
i have only just now applied these settings , so time willl tell, my only concern with lowering power settings on one AP is the effect it will have on clients that were connecting to that ap from a distance may drop off.
you did say that a possible cause for PTK failure is contention, How would I adress that ?
