Additional Notes

Windows 7 driver for the 3Com 11a/b/g Wireless PC Card with XJACK Antenna (3CRPAG175). Extracted from the 5.3.0.35-driver at http://www.dd-wrt.com/dd-wrtv2/down.php?path=downloads%2Fothers%2Fdrivers/ and changed only the description '3Com etc' at the end of the inf-file. I installed this driver under XP Pro and Windows 7 (7100) 32-bits. Will probably work as well under Vista 32-bits.
