of transmission to use the best rate achievable. Each wireless device first determines if
conditions diminish signal strength and then chooses one of four possible bit rates (1,
2, 5.5, or 11 Mbps) based on this learned information.
By default, the unit adaptively selects the highest possible rate for transmission. Select
the basic rates to be used among the following options: Auto, 1, 2, 5.5, or 11 Mbps.
For most networks the default setting, Auto will be the best choice. When (Auto Rate
Fall Back) is enabled the transmission rate will select the optimum rate. If obstacles or
interference are present, the system will automatically fall back to a lower rate.
Preamble Type: Preamble is the first sub-field of PPDU, which is the appropriate
frame format for transmission to PHY (Physical layer). There are two options, Short
Preamble and Long Preamble. The Short Preamble option improves throughput
performance. The Preamble type of Node should be the same as AP’s when in Access
Point Client mode.
6.2 Access control
If the user enables wireless access control, only those clients whose wireless MAC
addresses are in the access control list will be able to connect to your device. When
this option is enabled, no wireless clients will be able to connect if the list contains no
entries.
To save all the settings, click “Apply Changes”. After the device save all the settings,
it will show as following, then click “OK” to finish the saving.
Only those MAC addresses which match to the control list can associate with the
router. If the user wants to deny one of the MAC address listed in the list, check
“Selected” and click “Delete Selected” or click “Delete All” to deny all clients.
