My computer is experiencing difficulty connecting to the wireless
network.
! Ensure that your Access Point (AP) is powered on and that the
Wireless LED is lit.
! Ensure that your wireless adapter (PCI card, Notebook or
Ethernet adapter) is installed correctly and is active.
! Ensure that your wireless adapter’s radio signal is enabled.
Review your adapter’s documentation for further instructions.
! Ensure that your wireless adapter for your PC and the AP have
the same security settings that will allow your computer to access
the wireless network. Section 3: Wireless > Security details how
to adjust security settings.
! Ensure that your AP is within range of your router or is not behind
obstruction, for example metal structures will interfere with the
signal, as will 2.4 GHz cordless phones, and microwaves.
! Ensure that your antenna is connected and that your router’s
antenna is also connected.

My computer is experiencing difficulty in connecting to the AP.
! Check that all of your cable connections are tight and secured.
This includes the cables from the wall to your modem, between
the router and modem, and, if available, from the AP to your PC.
Ensure that your LEDs are not lit Red or not at all. For further
information about LED descriptions, see Section 1: Overview.
! Ensure that you are using Ethernet cables and not telephone
cables between the router and modem, router and PC, or if
available, AP and PC. Ethernet cables use a wider RJ-45 style
plug using 8 wires where telephone style plugs use the smaller
RJ-11 style plug using 4 to 6 wires.
The plug on the left is RJ-45; the plug on the right is RJ-11 – use only
RJ-45.
! Ensure that your Ethernet adapter is enabled. Check the System
Tray at the bottom right of your display to see an icon that looks
like a monitor. You can click on this to see the status of
your Ethernet adaptor. Also in Control Panel > Network and
Dial-Up Connections, you can examine the state of your Ethernet
adaptor.

I would like to see if my Internet connection is alive.
For this, you will use the ping command to test the connection.
Before attempting, ensure that Obtain an IP address automatically
has been selected in the computer’s settings and that you have an IP
address assigned. Refer to Section 2: Configuration > Configure
Your Computers, for further details.
1 Open a command prompt by clicking Start and Run.
! For Windows 98 and ME, in the Open field, type command
and press Enter or OK.
! For Windows 2000 and XP, type cmd.
! Or, navigate using your Start button to
Programs>Accessories>Command Prompt.
2 In the Command window, type ipconfig.
! You should see an IP address for your network adapter:
Ethernet Adapter Local Area Connection:
Connection-specific DNS Suffix.: Example.example.example.com.
IP Address. . . . . . . . . . . . : 192.168.40.3
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.40.1
3 In the Command window, type ping followed by the AP’s IP
address and press Enter. For example type: ping 192.168.40.3.
There is a good possibility that the Default Gateway’s IP address
is the AP’s IP address. You can verify the AP’s IP address on the
Control Panel > Network Access screen.
! If you receive a reply (the first word will be Reply…), then
your computer is connected to the AP. Proceed to Step 4.
! If you do NOT receive a reply, try from a different computer to
verify that the first PC is not the cause of the problem.
4 In the Command window, type ping and your ISP’s default
gateway and press Enter. For example type: ping 192.168.40.1.
! If you receive a reply (It might look something like this: Reply
from 216.109.125.72…), then your connection to the Internet
is alive and well. You can verify the ISP’s IP address at the
Gateway IP field on the Control Panel > Network Access
screen.

! If you do NOT receive a reply, try from a different computer to
verify that the first PC is not the cause of the problem.
5 If you cannot determine your ISP’s default gateway, ping
www.yahoo.com or another known web location.
I cannot access the Web-Based Configuration Utility for the AP.
! Verify your Ethernet connection to the AP.
! Verify that the IP address of the PC being used to configure the
AP is on the same network as the AP’s configuration IP address.
! The IP address of your network adapter must be on the same
network and not a duplicate of any others on the network (for
example: 192.168.40.3 and using a subnet mask of
255.255.255.0 can be used to login to the AP’s default IP address
of 192.168.40.1). Refer to Section 2: Configuration > Configure
Your Computers on how to adjust the IP address for your PC.
! Verify that you can ping the AP on this IP address.
! In the Command window, type ping and your AP’s default IP
address and press Enter. For example type:
ping 192.168.40.3
! If you have changed the factory configured default IP address
of the AP, you will need to set your network adapter
accordingly.
! Verify you are entering the correct URL in the browser. The
default is http://192.168.40.1. If you think you have changed the
IP address used to configure the AP and cannot remember it, you
must reset the unit back to factory defaults. To do this, press and
hold the reset button for more the 5 seconds. This clears the AP’s
user settings, including User ID, Password, IP Address, and
Subnet mask.
! Once the AP is reset to factory default, re-verify the Ethernet
connectivity and IP address issues.
! Verify you are using the latest version of IE or Netscape. IE 5.2
and below are not supported.
