Fast flash means WAN port traffic activity.

Wireless LAN (WLAN) Status LED

Blue

If the LED is on it indicates that wireless networking is enabled. If the LED

is flashing, the link is OK and data is being transmitted or received. If the

LED is off, the Wireless LAN has been disabled in the Router, or there is a

problem. Refer to

LAN Status LEDs (4 indicators)

Blue

If the LED is on, the link between the port and the next piece of network

equipment is OK. If the LED is flashing, the link is OK and data is being

transmitted or received. If the LED is off, nothing is connected, or the

connected device is switched off, or there is a problem with the

connection (refer to

THE

OUTER

WPS LED

Blue

WiFi Protected Setup (WPS) is a standard for easy and secure

establishment of a wireless network, allowing wireless clients to connect

securely to routers and access points. The WPS LED shows the status of

the WPS function. It has a number of modes to help monitor the status of

clients connecting to the Router using the WPS protocol. The status is

shown by three different flashing rates: slow, medium and quick and

when light constantly.

Note: The WPS function will be enabled for 2 minutes once WPS

enabled either by pressing the button or by starting the PIN mode via the

web interface. This time will end before 2 minutes if a client has

successfully connected. Only one client should be connected to the

Router using WPS at any one time. Attempting to connect two or more

clients at once may result in connection failures.

When the WPS button is pressed, or

WPS is initiated using the PIN

method in the web interface, the WPS LED will flash at a medium rate for

up to 2 minutes to indicate that a WPS connection can be made. When a

connection attempt is underway, the LED will flash slowly.

If the connection has been successful, the WPS LED will remain

illuminated for 5 minutes. If the connection attempt has failed, the WPS

LED will flash rapidly for 5 minutes. You can re-try the connection by

pressing the WPS button, when the connection process will re-start.

If you want to add a further client to the Router, you do not need to wait

for the 5 minute period to end. You can press the WPS button (or use the

PIN method via the web interface) as soon as the first client is successfully

connected.

Wireless Antenna

The antennas should be placed in a ‘V’ position when initially installed.

CAUTION:

Do not force the antennae beyond their mechanical stops.

Rotating the antennae further may cause damage.

WPS button

Press this button for 3 seconds when making WPS setup. Pushing the

WPS button will automatically enable WPS. Then initiate the WPS

procedure on the wireless NIC within two minutes. Refer to your wireless

NIC's documentation on this procedure. The wireless NIC will then be

securely added to your wireless network.

Ethernet Ports (4 ports)

Using suitable RJ-45 cables, you can connect your Router to a computer,

or to any other piece of equipment that has an Ethernet connection (for

example, a hub or a switch). These ports have an automatic MDI/MDIX

feature, which means either straight-through or a crossover cable can be

used.
