First off let me start by saying I am quite green when it comes to this equipment, I managed to get this project up and running with much help from the equipment manuals, tech notes, forums and a lot of google work.

This setup has been up and running now for around 4 years with little to no maintenance or monitoring, I have been getting a few reports of users not being able to move from one area to the next without getting disconnected from our wireless, all of our users (about 400 or so) are running on newer Lenovo laptops on Windows XP SP3.

I know this is extremely light in substance with regards to troubleshooting, but where would be a good starting point to begin with this issue?

We use one RADIUS server with Layer 2 WPA WPA2 AES security.

I appreciate your time.

I have been getting a few reports of users not being able to move from one area to the next without getting disconnected from our wireless,

So users are fine when they are NOT using Lenovo clients?

Disable Aeronet IE?

Disable 802.11b data rates?

Set Dynamic Channel Assignment to every 24-hours?

Update the firmware of the WLAN NICs of the troublesome Lenovo?
