I have a laptop with Vista and a laptop with XP. It seems that my Vista laptop for some reason roams to a different AP on a different floor and then back. (the laptop is not moved--it is at one location).My laptop with XP seems to stay on the same AP in that same location. The XP laptop does not roam. Not clear on why this is roaming and if any settings can be tweaked. Please help.
It seems that there are 2 APs which have same range power and therefore clients is flapping between them. For a testing purpose, lower the power of 10th floor AP. It will resolve this issue.
