I downloaded everything that was under the M11x option.
There were a few things that were related to wireless.
I checked to see if I downloaded all of them and they're all here.
If one of the downloads didn't work, I wouldn't even know which one it would be.
All of the wireless related downloads applied to:
Intel(R) WiFi Link 5100
AR8132 LAN 10/100
Wireless 1520 MiniCard WLAN for Desktops
Wireless 365 Bluetooth Module
Wireless 5620 EVDO-HSPA Mobile Broadband Mini-Card
