User provisioning for Advanced Wireless settings

This screen is used to set up the advanced wireless functions. These settings should only
be adjusted by an expert administrator as incorrect settings can reduce wireless
performance.
Beacon Interval
The Beacon Interval value indicates the frequency interval of the wireless beacon. A beacon
is a packet broadcast by the gateway to synchronize the wireless network. The default value
is 100ms.
DTIM Interval
This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM
field is a countdown field informing a client of the next window for listening to broadcast
and multicast messages. When the gateway has buffered broadcast or multicast messages
for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear
the beacons and receive the broadcast and multicast messages. The default value is 1;
user can select any other value from 1 to 255.
Fragmentation Threshold:
This value specifies the maximum size for a packet before data is fragmented into
multiple packets. In the event of a high packet error rate, the Fragmentation Threshold
may be slightly increased. Setting the Fragmentation Threshold too low may result in
poor network performance. Only a minor reduction of the default value is recommended.
