Hi


I have problems with the wireless network, I have users connected and suddenly start to feel the network latency and reduced the speed to be working at 54 mbps to 1 mbps down and then disconnect, it proceeded to change the version of IOS the WLC from version 5 to version 6 and proceeded to make a change in the Session Timeout, and began its maximum value soportabley are no longer disconnects users but I still have speed and low latency in the network, under the tx team and modify the velocities of 1 and 2 were supported Megas and 5.5 were below an continuous Osilo Mandatory but the customers who are working at 54 Mbps and then switch to 6 or 3 Mbps and then to 24 or 32 Mbps.
Any Idea ?

How many clients are connected to a particular AP.  From what I gather of the description of your problem it sounds that clients are overwhelming ONE AP with traffic.
