The driver provided by 3com (as well as 100% of the other websites in the world that have drivers for this unit) is version 18.104.22.168 and does NOT work with Windows XP. This driver is the driver that came with Windows XP, c \windows\inf\netbcm4u.inf ( with the included PNF file), which is version 22.214.171.124, BUT I have modified it to include information for the 3com 3C420 (as well as modifying the PNF file in a hex editor). I jsut copied these files into my c \windows\inf\ folder and windows was able to automatically pick it up when I plugged the unit into my system. I have only tried this on Windows XP Pro chances are, though, that it will work on Windows XP Home. I got no bluescreens in XP, like the 126.96.36.199's will give you, and i was able to use the internet. Good luck.

DriverGuide.com - Using DriverGuide's Installer
DriverGuide's installer software (Windows only) simplifies the driver installation process. It safely downloads and verifies your driver and then assists in the installation of it.
You may notice that the file size of the installer software is much smaller than the file size of your actual driver. The reason is that first the installer setup file is downloaded, and then the installer software does the work of fetching your driver from our fastest download server.
The installer setup file has been certified safe by leading-class virus and malware scanners.
Sometimes anti-virus software can report false positives. If this happens to you, we encourage you to submit the file you download to VirusTotal (a free, independent service which identifies malicious content) where you will see dozens of other anti-virus scanners report the file is perfectly safe.
The installer setup file may include a purely optional advertising offer which you are free to decline. We only work with trusted advertising partners.
Note: Windows only. Mobile, Mac OS and Linux users can choose other download options by deselecting the installer checkbox below the download button.
