If auto scan for SSID is used, the results will be displayed in the Search SSID table, thus simply click
on the required AP and SSID will be selected.
AdvancedAPSettings
Quality of service (WMM) – enable to support quality of service for prioritizing traffic.
Wireless VLAN ID – specify the VLAN ID for traffic tagging on particular radio interface. The Station
devices that associate using the particular SSID will be grouped into this VLAN.
WirelessMode:Station(ARPNAT)
Use Wireless Configuration to setup radio interface of the device.
Enable radio – use slide to enable or disable APC radio.
Operating country - displays APC unit operating country. The Country selection determines the
available channels and transmission power level based on regulatory restrictions in the operating
country. The country has been selected on the first step of the APC unit's installation, though can be
updated if required.
IEEE mode – specify the wireless network mode.
Tx power (dBm) – set the unit’s transmitting power at which the device will transmit data. The larger
the distance, the higher transmit power is required. To set transmit power level use the slider or enter
the value manually. When entering the transmit power value manually, the slider position will change
according to the entered value. The maximum transmit power level is limited to the allowed value by
country in which device is operating regulatory agency.
Channel width - The default channel bandwidth for 802.11 radio is 20MHz. The 802.11n allow
channel bonding in such way the total channel width becomes 40MHz.
AdvancedRadioSettings
Advanced parameters allow configuring the device to get the best performance/capacity of the link.
Max 802.11n MCS index – choose the maximum rates to specify the modulation and coding scheme
(MCS) rates at which data can be transmitted between the access point and the client. If there will be
an interference encountered, the device will step down to the highest rate that allows data
transmission.
Max legacy data rate – choose the maximum data rate in Mbps at which device should transmit
packets. It will attempt to transmit data at the highest data rate set. If there will be an interference
encountered, the device will step down to the highest rate that allows data transmission.
AMSDU – enable the AMSDU packet aggregation. If enabled, the maximum size of the 802.11 MAC
frames will be increased.
Short GI – enable short guard interval. If selected, then 400ns value will be used, else 800ns.
Fragmentation – specify the Fragmentation threshold using slider or enter the value manually [256-
2346 bytes]. This is the maximum size for a packet before data is fragmented into multiple packets.
Setting the Fragmentation threshold too low may result in poor network performance. Only minor
modifications of this value are recommended.
RTS/CTS – specify the RTS threshold using slider or enter the value manually [0-2347 bytes]. The
RTS threshold determines the packet size of a transmission and, through the use of an access point,
helps control traffic flow.
ACK timeout – specify the ACK timeout using slider or enter the value manually. Ack timeout can be
entered by defining the link distance or specifying time value. Too low value of the ACK timeout will
give very low throughput. A high value may slow down the link in noisy environment. A low value is far
worse than a value slightly too high. ACK Timeout value should be tuned to the optimal value for the
maximum link throughput.
