2  USB Adapter for Windows (XP & Vista) 
  Before You Begin 
During the installation, XP may need to copy systems files from its installation CD. 
Therefore,  you  may  need  a  copy  of  the  Windows  installation  CD  at  hand  before 
installing the drivers. On many systems, instead of a CD, the necessary installation 
files are archived on the hard disk in C:\WINDOWS \OPTIONS\CABS directory. 
WiFi  Alliance  certification  recommends  WPA2  AES  to  be  the  security 
mechanism under 11N mode. System driver will automatically bring down 
wireless data rate to 54Mbps if other security method such as WEP or WPA 
is used under 11n mode. 
If your 11N router is using security mechanism other than WPA2 AES, you 
are recommended to disable security setting or change it to WPA2 AES to 
fully utilize 11N capability.  This policy has no effect if connecting with b/g 
only wireless access point.
