Optimizing Broadcom Driver Advanced Properties

I'm interested in optimizing my Broadcom 1450 Dual Band WLAN Mini-PCI driver's advanced properties for best performance as we roll out the conversion of our Cisco wireless access points to Lightweght Mode; part of implementing Cisco WCS. We first noticed difficulties with our Latitude D600, D610 & D620's running WinXP Pro maintaining connection to the network with newer Cisco 1240 AP's, but the problems spread when we started upgrading the IOS of older Cisco 1200, 1210, & 1230 AP's prior to converting to Lightweight mode. The first step we've taken is to upgrade the wireless NIC driver on all of the Latitudes, but it would be nice to have some background and best practices on each of these settings. Some information is available at:
