Description
Band
The new amendment allows IEEE 80±.11g units to fall back to speeds of 11
Mbps, so IEEE 80±.11b and IEEE 80±.11g devices can coexist in t he same
network. The two standards apply to t he ±.4 GHz frequency band. IEEE
80±.11g creates data-rate parity at ±.4 GHz wit h t he IEEE 80±.11a standard,
which has a 54 Mbps rate at 5 GHz. (IEEE 80±.11a has ot her differences
compared to IEEE 80±.11b or g, such as offering more channels.)
Channel
Drop-down menu t hat allows selection of a specific channel.
Auto Channel
Timer (min)
Auto channel scan timer in minutes (0 to disable)
80±.11n/EWC
Wit h drop-down menu, “Auto” is for 11n and “Disable” is for 11g
Bandwidt h
Drop-down menu specifies t he following bandwidt h: ±0MHz and 40MHz.
Control
Sideband
This is available for 40MHz. Drop-down menu allows selecting upper
sideband or lower sideband
80±.11n Rate
Drop-down menu specifies t he following fixed rates. The maximum rate
for bandwidt h, ±0MHz, is 130MHz and t he maximum bandwidt h, 40MHz, is
±70MHz
80±.11n
Protection
It is similar as 80±.11g protection. In Auto mode t he router will use RTS/
CTS to improve 80±.11n performance in mixed 80±.11n/ 80±.11g/ 80±.11b
networks. Turn protection off to maximize 80±.11n t hroughput under most
conditions.
Support
80±.11n client
only
Drop-down menu allows selecting “On/O ff ”. Choosing “On” allows t he
client wit h 11n only to connect, not for 11g or 11b; choosing “O ff ” allows
t he client wit h 11n/11g/11b to connect
54g Rate
Drop-down menu t hat specifies t he following fixed rates: Auto: Default.
Uses t he 11 Mbps data rate when possible but drops to lower rates
when necessary.
1 Mbps, ±Mbps, 5.5Mbps, or 11Mbps fixed rates. The
appropriate setting is dependent on signal strengt h.
Multicast Rate
Setting multicast packet transmit rate.
Basic Rate
Setting basic transmit rate.
Fragmentation
Threshold
A t hreshold, specified in bytes, t hat determines whet her packets will be
fragmented and at what size.
On an 80±.11 WLAN, packets t hat exceed
t he fragmentation t hreshold are fragmented, i.e., split into, smaller
units suitable for t he circuit size.
Packets smaller t han t he specified
fragmentation t hreshold value are not fragmented.
Enter a value between
±56 and ±346. If you experience a high packet error rate, try to slightly
increase your Fragmentation Threshold. The value should remain at its
default setting of ±346.
Setting t he Fragmentation Threshold too low may
result in poor performance.
RTS Threshold
Request to Send, when set in bytes, specifies t he packet size beyond
which t he WLAN Card invokes its RTS/CTS mechanism.
Packets t hat
exceed t he specified RTS t hreshold trigger t he RTS/CTS mechanism. The
NIC transmits smaller packet wit hout using RTS/CTS. The default setting of
±347 (maximum lengt h) disables RTS Threshold.
