Fragmentation
Threshold
This is the maximum data fragment size that can be sent. Enter a
value between 256 and 2432.
RTS Threshold
Use CTS/RTS to reduce data collisions on the wireless network if you
have wireless clients that are associated with the same AP but out of
range of one another. When enabled, a wireless client sends an RTS
(Request To Send) and then waits for a CTS (Clear To Send) before it
transmits. This stops wireless clients from transmitting packets at the
same time (and causing data collisions).
A wireless client sends an RTS for all packets larger than the number
(of bytes) that you enter here. Set the RTS equal to or higher than
the fragmentation threshold to turn RTS off.
DTIM Interval
Delivery Traffic Indication Message (DTIM) is the time period after
which broadcast and multicast packets are transmitted to mobile
clients in the Power Saving mode. A high DTIM value can cause
clients to lose connectivity with
the network. This value can be set from 1 to 100.
Beacon Interval
When a wirelessly networked device sends a beacon, it includes with
it a beacon interval. This specifies the time period before the device
sends the beacon again.
The interval tells receiving devices on the network how long they can
wait in low power mode before waking up to handle the beacon. This
value can be set from 20ms to 1000ms. A high value helps save
current consumption of the access point.
Global Max Clients
Specify the maximum number (from 1 to 64) of the wireless stations
that may connect to the ZyXEL Device.
XPress™
Technology
Select this for higher speeds, especially if you have both IEEE
802.11b and IEEE 802.11g wireless clients. The wireless clients do
not have to support XPress™ Technology, although the performance
enhancement is greater if they do.
Afterburner
Technology
Select this for higher speeds if the wireless clients also support
afterburner technology.
Transmit Power
Set the output power of the ZyXEL Device. If there is a high density
of APs in an area, decrease the output power to reduce interference
with other APs.
WMM (Wi-Fi
Multimedia)
Use WMM (Wifi MultiMedia) to prioritize services in wireless traffic.
Select
Auto
to automatically prioritize services according to the ToS
value in the IP header of packets.
Select
Enable
to prioritize services according to the ZyXEL Device’s
Quality of Service settings.
Select
Disable
to not prioritize services in wireless traffic.
WMM No
Acknowledgement
When using WMM, you can enable this to have the ZyXEL Device not
re-send data if an error occurs. This can increase throughput speed
but may also increase errors, especially in an environment with a lot
of Radio Frequency (RF) noise. Otherwise leave it disabled.
