Chapter 5: Wireless Tab

The Wireless tab contains everything needed by the

operator to set up the wireless part of the link. This

includes device wireless mode, SSID, country settings,

channel and frequency settings, data rates, and wireless

security.

Basic Wireless Settings

The general wireless settings, such as wireless mode,

wireless network name (SSID), country code, 802.11 mode,

output power and data rates can be configured in this

section.

Wireless Mode Allows you to specify the operating

mode of the device. The mode depends on the network

topology requirements. There are 4 operating modes

supported on the AirRouter HP: Station, Station WDS,

Access Point, Access Point WDS.

• Station This is a client mode, which connects the

AirRouter HP to an Access Point. In Station mode,

the AirRouter HP acts as the subscriber Station while

connecting to the Access Point. The SSID of the

Access Point is used and all the traffic to/from the

network devices connected to the Ethernet interface is

forwarded.

Subscriber Station uses the arpnat technique which may

result in a lack of transparency while passing-through

broadcast packets in bridge mode.

Chapter 5: Wireless TabAirRouter

HP User Guide

Ubiquiti Networks, Inc.

• Station WDS WDS stands for Wireless Distribution

System. Station WDS should be used while connecting

to an Access Point that is operating in WDS mode. This

mode is compatible with WPA/WPA2 encryption.

Station WDS mode enables packet forwarding at the

Layer 2 level.

The benefit of Station WDS is improved performance

and faster throughput. Station WDS - Bridge mode is

fully transparent for all Layer 2 protocols.

• Access Point This is 802.11 Access Point mode.

• Access Point WDS This is an 802.11 Access Point which

allows for Layer 2 bridging with Station WDS devices

using the WDS protocol. Access Point WDS is not fully

compatible with WPA/WPA2 encryption.

WDS allows you to bridge wireless traffic between

devices which are operating in Access Point mode.

Access Point is usually connected to a wired network

(Ethernet LAN) allowing wireless connection to the

wired network. By connecting Access Points to one

another in an extended service set using the WDS,

distant Ethernet connections can be bridged into a

single LAN.

It is very important that network loops should not be

created with either WDS bridges or combinations of

wired (Ethernet) connections and WDS bridges. Tree

or Star shape network topology should be used in all

WDS use-cases (i.e. If Access Point 2 and Access Point

3 are specified as the WDS peers of Access Point 1,

Access Point 2 should not be specified as the WDS peer

of Access Point 3 and Access Point 3 should not be

specified as the WDS peer of Access Point 2 in any case).

Mesh and Ring network topologies are not supported

by WDS and should be avoided in all use cases.

Note: Station WDS and Access Point WDS mode

use the WDS protocol which is not defined as

the standard thus compatibility issues between

equipment from different vendors may arise.

Note: When connecting devices in Access Point

WDS to Access Point WDS mode, the WPA/

WPA2 security methods will not function.

When connecting Access Point WDS devices

to other Access Point WDS device use none or

the WEP security method. However, this may

compromise the security of your network.

When connecting Station WDS clients to an

Access Point WDS device, all security methods

are available and work properly.

operating in WDS mode should have the same SSID

as the WDS Peer in order to establish the connection

automatically while the Auto option is enabled. This

configuration is also known as repeater mode. AP

WDS Auto option can not be selected if any type

of WPA or WPA2 security is used as WPA requires

different roles on AP configuration (authenticator or

supplicant).

Note: Access Point operating in WDS mode

and all the WDS Peers must operate on the

same frequency channel, use the same channel

spectrum width and the same security settings.

SSID The wireless network name or SSID (Service Set

Identifier) used to identify your 802.11 wireless LAN

should be specified while operating in Access Point or

Access Point WDS mode. All the client devices within

range will receive broadcast messages from the access

point advertising this SSID.

While operating in Station or Station WDS mode, you

should specify the SSID of the Access Point the AirRouter

HP is associated with. There can be several Access Points

with an identical SSID. If the SSID is set to “Any” the station

will connect to any available Access Point.

Select (Only applicable in Station and Station WDS mode.)

The list of the available Access Points can be retrieved

using the Select button.

This control activates Site Survey tool which is used for

the AP selection. Site Survey will search for the available

wireless networks in range on all supported channels

and allows you to select one for association. In case the

selected network uses encryption, you’ll need to set

security parameters in the Wireless Security section.

Select the Access Point from the list and click the Select

button for association. This will automatically enter the

name of the Access Point into the SSID field and display

the appropriate security options in the Wireless Security

section at the bottom of the page.

Or, to lock the station to a particular Access Point, select

the Access Point from the list and click the Lock to AP

button for association. This will automatically enter the

name of the Access Point into the SSID field, enter the

MAC Address into the Lock to AP MAC field and display

the appropriate security options in the Wireless Security

section at the bottom of the page.

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.

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.

Lock to AP MAC (Only applicable in Station and Station

WDS mode.) This allows the station to always maintain

a connection to a particular Access Point with a specific

MAC address. This is useful as sometimes there can be

multiple Access Points using the same SSID. With Access

Point lock on, the station will lock to a specific MAC

Address and not roam between several Access Points with

the same SSID.

Country Code Each country has their own power level

and frequency regulations. To ensure the AirRouter HP

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.

IEEE 802.11 Mode Displays the radio standards used for

the AirRouter HP.

Channel Width Displays the spectral width of the radio

channel. Supported wireless channel spectrum widths:

•

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

HP when the channel width is set to 5/10 MHz.

Some devices may not be able to connect using

the 40 MHz setting.

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. Options include Enabled and

Disabled.

Note: Channel shifting is not compatible with

legacy products.

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.

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.

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.

Options include Upper Channel and Lower Channel.

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.

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 HP. 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.

Max Data Rate, Mbps This defines the data rate (in Mbps)

at which the device should transmit wireless packets.

RADIUS is a networking protocol providing centralized

Authentication, Authorization, and Accounting (AAA)

management for computers in order to connect to, and

use a network service.

Radius Server Port Specifies the RADIUS Server’s UDP

port. The most commonly used port is 1812, but that

depends on the RADIUS Server you are using.

Radius Server Secret Specifies the password. A shared

secret is a case-sensitive text string used to validate

communication between two RADIUS devices. Click Show

to see the actual characters being typed.

See “MAC ACL” on page 17 for more information on

this option.

Note: When connecting devices in AP-WDS-to-

AP-WDS mode, the WPA/WPA2 security methods

will not function. When connecting AP-WDS

devices to another AP-WDS device use none or

the WEP security method. However, this may

compromise the security of your network. In case

of connecting STA-WDS clients to an AP-WDS

device, all security methods are available and

work properly.
