Version: Wireless Lan Broadcom Minipci Ver.18.104.22.168.zip 22.214.171.124
Perfect for a Dell Inspiron 5100. Many other drivers would not correctly install the card on XP. The TrueMobile 1370 driver from support.dell.com might have worked (uses the same Broadcom chip), but this one definitely hit the spot.
No cons so far
If you've spent hours looking for a driver for the cheap WLAN mini-PCI Broadcom 4318 cards sold on ebay, this is your final hassle-free URL.
