INTRODUCING THE ROUTER

Welcome to the world of networking with 3Com®. In the modern business environment, communication and sharing information is crucial. Computer networks have proved to be one of the fastest modes of communication but, until recently, only large businesses could afford the networking advantage.

Wireless 11n ADSL Firewall Router

The 3Com Wireless 11n ADSL Firewall Router is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several wired and wireless computers. The Router also provides protection in the form of an electronic “firewall” preventing anyone outside of your network from seeing your files or damaging your computers. The Router can also prevent your users from accessing Web sites which you find unsuitable.

Figure 1 shows an example network without a Router. In this network,

only one computer is connected to the Internet. This computer must always be powered on for the other computers on the network to access the Internet.

12 CHAPTER 1: INTRODUCING THE ROUTER

Figure 1 Example Network Without a Router

When you use the Router in your network (Figure 2 and Figure 3), it becomes your connection to the Internet. Connections can be made directly to the Router, or to an OfficeConnect Switch or Hub, expanding the number of computers you can have in your network.

that help describe the state of various networking and connection operations.

Figure 4 Router - Front Panel

16 CHAPTER 1: INTRODUCING THE ROUTER

1 Power LED (Illuminated Logo)

White

The 3Com logo serves as power OK indicator. This LED will light if the router is receiving power from the power adapter. If it is not lit check the power adapter connections. Refer to Chapter 6 Troubleshooting

2 Alert LED

Amber

Fast flash during self test. If self test fails the LED will remain on. Fast flash during software upgrade. Fast flash for software reset to the factory defaults. Fast flash for hardware reset to the factory defaults. The LED is on for 2 seconds when the firewall detects a hacker attack.

3ADSL Sync

Blue

LED on indicates the Internet connection is on. This LED flashes during configuration at power up.

4ADSL Data

Blue

Fast flash means transmitting/receiving data. Slow flash means ADSL connection is down.

5 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 Chapter 6 Troubleshooting

6 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 Chapter 6 Troubleshooting

). The port will

automatically adjust to the correct speed and duplex.

Physical Features 17

7 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 is 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.
