Transmission Rate
— The transmission rate at which data packets are
transmitted by the station or the AP. You can set this to Fully Automatic, 1Mb
(that is, 1 Mbps), 2Mb, 5.5Mb, or 11Mb. Usually this should be set to Fully
Automatic. In an electromagnetically “noisy” environment, a lower rate can
provide more stable transmission quality.
•
Channel
— Ad-hoc networks only. In a multiple-cell network topology,
overlapping and/or adjacent cells using different channels can operate
simultaneously without interference if the frequency distance between the
center frequencies is at least 30 MHz. For example, channels 1, 7, and 13, are
non-overlapping channels.
In the case of an infrastructure network, changing the channel number has no
affect, as the channel is scanned for automatically. The station will look for an
AP with the same SSID, and automatically associate with it.
•
Power Saving Mode
— Power-saving mode is currently unavailable on the
NWH4020. On adapters that do have a power-saving mode, performance is
degraded when that mode is enabled.
