* The data rate may differ from the real data transmission rate.
** 11a mode is only supported when it is connected to an IEEE802.11a device (e.g. Access Point supporting
IEEE802.11a).
*** 11g mode is supported only when you are connected to an IEEE 802.11g device (e.g. An Access Point supporting IEEE
802.11g).
**** 11n mode is only supported when it is connected to an IEEE802.11n device (e.g. Access Point supporting
IEEE802.11n). The data rate in 11n mode is determined by the number of antenna and Access Point type.
