Advantek Networks AWN-USB-54S user manual

802.11B only – This adapter can be compatible with both 802.11g and 802.11b wireless stations. If there are only 802.11b wireless stations in the network, you can set the adapter to this mode.

802.11G only –This adapter can be compatible with both 802.11g and 802.11b wireless stations. If there are only 802.11g wireless stations in the network, you can set the adapter to this mode.

Ad Hoc Wireless mode: There are four types. 802.11B only, 802.11 B/G mixed 802.11A only, and 802.11G only modes are supported.

Select Your Country Region Code: The available channel differs from different countries.

For example: USA (FCC) is channel 1-11, Europe (ETSI) is channel 1-13. The operating frequency channel will be restricted to the country user located before importing. If you are in different country, you have to adjust the channel setting to comply the regulation of the country.

11B/G Protection: If you have a mix of 802.11b & 802.11g wireless stations in the network, it is recommended to enable the protection mechanism. This mechanism can decrease the rate of data collision between 802.11b and 802.11g wireless stations. When the protection mode is enabled, the throughput of the adapter will be a little lower due to many of frame traffic should be transmitted.

Auto – Based on the status of network and automatically disable/enable protection mode.

On – Always enable the protection mode.

Off – Always disable the protection mode.

Tx Rate: Manually force the Transmit using selected rate. Default is auto. There are several options including Auto/1/2/5.5/6/9/12/18/24/36/48/54Mbps for you to select. When the “Auto” is selected, the device will choose the most suitable transmission rate automatically. The higher data rate you designated in the network, the shorter distance is allowed between the card and the wireless stations.

When the wireless mode is “802.11 B only”, the maximum data rate is 11 Mbps (11b) so that there are only “Auto/1/2/5.5/11Mbps” options you can select.

Tx BURST: The Burst enables the adapter to deliver the better throughput in the same period and environment.

Enable TCP Window Size: The TCP Window is the amount of data a sender can send on a particular connection before it gets an acknowledgment back from the receiver that it has gotten some of it. When the Router or AP card is connecting to have set up the TCP Window, you can enable the parameter to meet the data size for the Router or AP connection. The larger TCP Window the better performance.

Fast Roaming at -70dBm: You can enable the parameter when you want to fast roaming to the network nearby without intercepting the wireless connection, especially the adapter is
