802.11b Preamble: The preamble is part of the IEEE 802.11b physical layer specification. All 802.11b devices are mandatory to support the long preamble format, but may optionally support
the short preamble. This Wireless LAN Card supports the short preamble. The default Short & Long option allows to communicate with other 802.11b devices which support short preamble to
boost the throughput. If your device is having trouble to communicate with other 802.11b devices, then you may try to select the Long Only option.
QoS: Specifies whether to enable the Wireless LAN Card to cooperate in a network using Quality of Service.
Transmit Power Level: Specifies the transmit power as required.
Wireless Mode: Specifies the wireless operation mode. The Wireless LAN Card will scans the radio signals only in the base band you specified.
•
5 GHz 54 Mbps: Specifies whether to use 54 Mbps mode for 802.11a radio space.
•
5GHz 108 Mbps: Specifies whether to enable turbo mode for 802.11a radio space. If enabled, the WLAN card scans channels for 802.11a turbo modes.
•
2.4 GHz 11 Mbps: Specifies whether to use 11 Mbps mode for 802.11b radio space.
You can use the Wireless Mode setting to control whether to roam between 802.11a and 802.11b networks or just roam in a single network.
To roam between 802.11a and 802.11b network…
To have your wireless station automatically roam between 802.11a and 802.11b networks, select 2.4 GHz 11Mbps and one or both 5 GHz modes as required.
To roam in a single 802.11a or 802.11b network…
If you want your wireless station to roam only in 802.11a or 802.11b network, only select the corresponding band as the wireless mode.
Wireless Mode When Starting Ad Hoc Network: Only effective when connection to an Ad Hoc network. Specifies a band to establish an Ad Hoc network if no matching SSID is found after
scanning all available modes.
