Radio Settings
The following items are displayed on this page:
◆
High Throughput Mode — The access point provides a channel bandwidth of
20 MHz by default giving an 802.11g connection speed of 54 Mbps and a
802.11n connection speed of up to 108 Mbps, and ensures backward
compliance for slower 802.11b devices. Setting the HT Channel Bandwidth to
40 MHz increases connection speed for 802.11n up to 300 Mbps. HT40plus
indicates that the secondary channel is above the primary channel. HT40minus
indicates that the secondary channel is below the primary channel.
(Default: HT20; Range:HT20, HT40PLUS, HT40MINUS)
◆
Radio Channel — The radio channel that the access point uses to
communicate with wireless clients. When multiple access points are deployed
in the same area, set the channel on neighboring access points at least five
channels apart to avoid interference with each other. For example, for 11g/n
HT20 mode you can deploy up to three access points in the same area using
channels 1, 6, 11. Note that wireless clients automatically set the channel to the
same as that used by the access point to which it is linked. (The available
channels are dependent on the Radio Mode, High Throughput Mode, and
Country Code settings.)
◆
Auto Channel — Selecting Auto Select enables the access point to
automatically select an unoccupied radio channel.
◆
Interference Channel Recover — Rescans all channels when interference is
detected on the current channel, and then changes to a clear channel.
(Default: Disabled)
◆
Antenna — Sets the antenna options for this AP to "system default. "
◆
Transmit Power — Adjusts the power of the radio signals transmitted from the
access point. The higher the transmission power, the farther the transmission
range. Power selection is not just a trade off between coverage area and
maximum supported clients. You also have to ensure that high-power signals
do not interfere with the operation of other radio devices in the service area.
(Range - Percentage mode: min, 12.5%, 25%, 50%, 100%; Default: 100%)
(Range - dBm mode: 3-20 dBm; Default: 18 dBm)
◆
Maximum Association Clients — The total maximum number of clients that
may associate with the radio. (Range: 1-127; Default: 127)
◆
Radio Mode — Defines the radio operation mode.
Radio 0 (2.4 GHz Radio) — Default: 11n (g compatible); Options: 11n (b&g
■
compatible), 11n (g compatible).
Radio 1 (5 GHz Radio) — Default: 11n; Options: 11n (a compatible), 11n.
