Before You Begin
Note: 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.
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.
