Click Scan to refresh the list of available wireless networks.  
The Site Survey channel scan list can be modified using  
the Channel Scan List control.  
The benefits of this are private networking and inherent  
security. Using channel-shifting, networks instantly  
become invisible to the millions of Wi-Fi devices in the  
world.  
Hide SSID (Only applicable in Access Point and Access  
Point WDS mode.) When this option is enabled, the SSID  
(wireless network name) will not be broadcast to wireless  
stations.  
Frequency, MHz (Only applicable in Access Point or  
Access Point WDS mode.) Select the wireless channel  
while operating in Access Point mode. Multiple frequency  
channels are available to avoid interference between  
nearby access points. The channel list varies depending on  
the selected country code, IEEE 802.11 mode and Channel  
Spectrum Width and Channel Shifting option.  
Lock to AP MAC (Only applicable in Station and Station  
WDS mode.) This allows the station to always maintain a  
connection to a particular AP with a specific MAC address.  
This is useful as sometimes there can be multiple access  
points using the same SSID. With AP lock on, the station  
will lock to a specific MAC address and not roam between  
several Access Points with the same SSID.  
Obey regulatory Rules Option must remain enabled  
while it will force the transmit output power to be  
compliant with the regulations of the selected country. In  
this case, it will not be possible to set equivalent isotropic  
radiated power (EIRP) above the amount allowed per  
regulatory domain (different maximum output power  
levels and antenna gains are allowed for each IEEE  
802.11b/g/n regulatory domain thus country).  
Country Code Each country has their own power level  
and frequency regulations. To ensure the AirRouter  
operates under the necessary regulatory compliance  
rules, be sure to select the country where your device  
will be used. The channel list, output power limits, IEEE  
802.11 and Channel Spectrum Width modes will be tuned  
according to the regulations of the selected country.  
Extension Channel (Only applicable in Access Point or  
Access Point WDS mode with 40 MHz channel width.)  
Indicates the use of channel bonding that allows the  
AirMax network to use two channels at once. Using  
two channels improves the performance of the Wi-Fi  
connection. It is automatically selected by the system.  
IEEE 802.11 Mode Displays the radio standards used for  
the AirRouter.  
Channel Width Displays the spectral width of the radio  
channel. Supported wireless channel spectrum widths:  
Channel Scan List, MHz (Only applicable in Station or  
Station WDS mode.) This will confine scanning only to the  
selected channels. The benefits of this are faster scanning  
as well as filtering out unwanted AP’s in the results. Site  
Survey tool will look for the Access Points in selected  
channels only. Once enabled, click Edit to open the  
Channel Scan List window.  
5 MHz is the channel spectrum with the width of 5 MHz  
(known as Quarter-Rate mode).  
10 MHz is the channel spectrum with the width of 10  
MHz (known as Half-Rate mode).  
20 MHz is the standard channel spectrum width  
(selected by default).  
40 MHz is the channel spectrum with the width of 40  
MHz.  
Auto 20/40MHz (Only applicable in Station or Station  
WDS mode.) It offers better compatibility.  
Note: Laptops cannot connect to the AirRouter  
when the channel width is set to 5/10 MHz.  
Some devices may not be able to connect using  
the 40 MHz setting.  
Select the channels that you want to scan and click OK or  
click Close to close the window without any selections.  
Output Power This defines the maximum average  
transmit output power (in dBm) of the AirRouter. The  
output power can be specified using the slider. When  
entering the output power value manually, the slider  
position will change according to the entered value. The  
transmit power level maximum is limited according to the  
country regulations. Output power is the output power  
delivered to the internal antenna.  
Channel Shifting Enables special channels which have  
the frequency offset from the standard 802.11b/g/n  
channels. This is a proprietary Ubiquiti Networks  
developed feature. While 802.11 networks have standard  
channels spaced every 5 MHz apart, channel shifting uses  
non-standard channels offset from the standard channels.  
All the channels can be shifted by 5 MHz (in 802.11n) or  
2 MHz (in 802.11bgn) from the default central channel  
frequency.  
Max Data Rate, Mbps This defines the data rate (in Mbps)  
at which the device should transmit wireless packets.  
You can fix a specific data rate between MCS 0 and MCS  
7. It is recommended that you use the automatic option,  
especially if you are having trouble getting connected or  
losing data at a higher rate. In this case, the lower data  
rates will be used automatically. If you select 20 MHz  
Note: Channel shifting is not compatible with  
legacy products.
