I have 3 Cisco 1242 WAPs that I have deployed at a site that has NO RADIUS/AAA devices. I have given all of them a diffenent channel (1,6,11), but the same SSID and crypto (WPA2-PSK). The issue is when a machine boots up it associates with the closest/strongest AP, but as the device "roams" it does not which to a different AP. It stays assocatied with the original AP until that signal is gone. Then it quickly associates with the closest AP with no problem.
How do I get the device to associate with the strongest WAP? I have research "fast roaming and WDS" but it seems like you need EAP/LEAP and they do NOT have that at all.

Hi,
wpa2+aes+preshared-key provides fast roaming as there is no radius involved.
what you need to do is to make you cell size smaller to avoid sticky clients down-rate-shifting all the way from 54mbps to 1mbps.
disable data rates under the radio interface(s) from 1 to 5.5 and see how it goes.
thanks

Update your client driver and disable lower data rates as well as tune radio tx power.

I just wanted to let everyone know what I have found about this option. Cisco WAPs offer roaming as a built in option, but here is how it works. Out of the box of a WAP ( I am using G so I will refrence G speed) the WAP has the speed 1 - 56 turned on. What this means is once your deivce associates with the WAP it will NOT look for another WAP until the spped/rate drops below 1Mbps. It doesnt matter if you walk to another area and sit you device on the 2nd WAP that has a stronger signal. To stop this you need to go into the radio interface and turn off lower speeds. This will allow the deivce to start looking for other stronger WAPs once it reaches the lowest programmed speed.
under the radio interface use the speed command to only turn on the higher rates!
