Band: Another term for spectrum used to indicate a
particular set of frequencies. Wireless networking protocols
work in either 2.4GHz (802.11b/g) or the 5 GHz band
(802.11a).
Channel: Select the appropriate channel from the provided
list. All devices in your wireless network must use the same
channel in order to function correctly. It is 11 by default.
Rate: The range is 1Mbit/s–54Mbit/s. The transmission rate
depends on the speed of your wireless network. You can
select one rate or the default Auto. If you select Auto,
HG520 will automatically obtain the fastest rate.
Multicast Rate: In layered multicasting, data is transmitted
in multiple layers. The source encodes the signal in layers,
and a subset of these layers is sent to the receivers,
depending on the receiver requirements, and the congestion
of the path from the source to the receiver. Layered
multicasting is a form of multirate multicasting, since
different receivers in the same multicast group can receive
traffic at different rates.
Basic Rate: Select the basic rate that wireless clients
support.
Fragmentation Threshold: It is 2346 by default. The range
is 256–2346 bytes.
This value specifies the maximum packet size after data
fragmentation.
If there is a high packet error rate, you can lower the
fragmentation threshold.
Setting the fragmentation too low may result in poor network
performance.
Only slight adjustment of this value is recommended.
