I have the 4400 controllers with 1130 APs. I have 32 users connected to two access point. Once users try to log in, the whole network gets really slow. When I sniffed the air there were a lot of "duration attacks"
I found what duration attack means from here: http://manageengine.adventnet.com/products/wifi-manager/duration-attack.html
I just want to know if anyone knows how we can prevent this from happening. We tested out HP access points with the same class and doesn't seem to have that issue. Thanks for your help. If you need more info let me know.
