Newest Broadcom (Generic bcmwl5.sys) wireless drivers for XP seem to be from late 2007 - v4.170.25.12

I was helping my father-in-law get on our home wireless network tonight and needed to find updated Broadcom drivers for his wireless adapter built into his HP/Compaq laptop.

Despite what the site might say for his laptop model, the most recent generic build of the 802.11b/g drivers seem to be located here. As usual, the "branded" OEM drivers are lagging behind, but the funny part is, this is coming from an HP page for wireless printers.

Even though they say they are for Windows 2000, they also include versions for Windows XP and Windows XP 64-bit.

Build date seems to be from late 2007 with a version code of 4.170.25.12.

Once the drivers were updated from a build from 2004 to these, and the WPA2 hotfix for XP was installed, things seemed to work very well.
WPA2 is excellent, especially combined with a RADIUS server.
