Basic Wireless Settings
In this section, configure the basic wireless settings, such
as wireless mode, wireless network name (SSID), country
code, 802.11 mode, output power, and data rates.
Wireless Mode Specify the Wireless Mode of the
device. The mode depends on the network topology
requirements. airOS supports the following modes:
•
Station If you have a client device to connect to an
AP, configure the client device as Station mode. The
client device acts as the subscriber station while it is
connecting to the AP. The SSID of the AP is used, and all
the traffic to and from the network devices connected to
the Ethernet interface is forwarded.
Note: If WDS (Transparent Bridge Mode) is
disabled, the radio uses arpnat, which results
in non-transparent bridging. To have a fully
transparent bridge, select Station and then
enable WDS (Transparent Bridge Mode).
• Access Point If you have a single device to act as
an AP, configure it as Access Point mode. The device
functions as an AP that connects multiple client devices.
If you have multiple APs repeating signals where
Ethernet connections are not readily available, then use
AP‑Repeater mode.
Note: For Access Point (WDS) mode, select Access
Point and then enable WDS (Transparent Bridge
Mode).
• AP‑Repeater If you have multiple APs, configure them
as AP‑Repeater mode to create a wireless network
infrastructure, WDS. If the Auto option is enabled, all APs
using the same wireless mode (AP‑Repeater) and SSID
automatically establish the WDS connections. (Client
devices can still connect to APs in AP‑Repeater mode.)
Note: For AP‑Repeater mode, the WPA ™ /WPA2 ™
security methods will not work; instead, use
none or the WEP security method (this may
compromise the security of your network).
You still have the option of using RADIUS MAC
authentication and MAC ACL.
WDS (Transparent Bridge Mode) (Available in Access
Point or Station mode only.) In most cases, we recommend
that you use WDS because it enables transparent Layer 2
traffic. To use WDS with Station or Access Point mode,
check the Enable box.
The WDS protocol is not defined as a standard, so there
may be compatibility issues between equipment from
different vendors.
•
Station (WDS) Station (WDS) mode should be used if
the device is connecting to an AP in Access Point (WDS)
mode.
• Access Point (WDS) Access Point (WDS) mode allows
Layer 2 bridging with devices in Station (WDS) mode.
Note: If you connect devices running in Station
(WDS) mode to a device running in Access
Point (WDS) mode, then all security methods
(including WPA/WPA2 encryption) are available
and work properly.
Auto (Available in AP‑Repeater mode only.) Check the
Auto box to automatically establish WDS connections
between APs in AP‑Repeater mode. If the Auto option
is enabled, the device will choose WDS Peers (APs in
AP‑Repeater mode) according to the SSID setting. While
the device is in AP‑Repeater mode, you cannot enable the
Auto option if you use any type of WPA or WPA2 security
because WPA or WPA2 requires different roles on AP
configuration (authenticator or supplicant).
Note: All APs in AP‑Repeater mode (WDS Peers)
must operate on the same frequency channel, use
the same channel spectrum width, and share the
same security settings.
WDS Peers (Available in AP‑Repeater mode only.) If you
do not enable the Auto option, then specify the APs in
AP‑Repeater mode. Enter the MAC address of each AP
in each WDS Peers field. One MAC address should be
specified for a Point-to-Point (PtP) connection use case.
You can specify up to six WDS Peers for a Point-to-Multi-
Point (PtMP) connection use case.
SSID If the device is operating in Access Point or
AP‑Repeater mode, specify the wireless network name or
SSID (Service Set Identifier) used to identify your WLAN.
All the client devices within range will receive broadcast
messages from the AP advertising this SSID.
If the device is operating in Station mode, specify the
SSID of the AP the device is associated with. There can be
several APs with an identical SSID.
Select (Available in Station mode only.) To display the list
of available APs, click Select.
The Site Survey tool will search for available wireless
networks in range on all supported channels and allow
you to select one for association. In case the selected
network uses encryption, you’ll need to configure security
on the Wireless tab and save those changes before you use
the Site Survey tool.
•
Lock to AP Select the AP from the list. Click Lock to AP
to allow the station to always maintain a connection to
an AP with a specific MAC address.
• Select Select the AP from the list and click Select for
association.
• Scan Click Scan to refresh the list of available wireless
networks.
You can change the list of Scanned Frequencies for the
Site Survey using the Frequency Scan List option.
