Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and
operation of the DWL-2700AP Wireless Access Point. We cover various aspects of the
network setup, including the network adapters. Please read the following if you are
having problems.

Note: It is recommended that you use an Ethernet connection to configure the
DWL-2700AP.

1. The computer used to configure the DWL-2700AP cannot access the
Configuration menu.

Check that the Ethernet LED on the DWL-2700AP is ON. If the LED is not ON,

check that the cable for the Ethernet connection is securely inserted.

Check that the Ethernet Adapter is working properly. Please see item 3 (Check

that the drivers for the network adapters are installed properly) in this

Troubleshooting section to check that the drivers are loaded properly.

Troubleshooting

Check that the IP address is in the same range and subnet as the DWL-2700AP.

Please see Checking the IP Address in Windows® XP in the Networking Basics
section of this manual.

Note: The IP address of the DWL-2700AP is 192.168.0.50. All the computers on the
network must have a unique IP address in the same range, e.g., 192.168.0.x. Any
computers that have identical IP addresses will not be visible on the network. They
must all have the same subnet mask, e.g., 255.255.255.0.

Do a Ping test to make sure that the DWL-2700AP is responding. Go to

Start>Run>Type Command>Type ping 192.168.0.50. A successful ping will show

four replies.

Note: If you have changed the default IP address, make sure to ping the correct IP
address assigned to the DWL-2700AP.

2. The wireless client cannot access the Internet in the Infrastructure mode.

Make sure the wireless client is associated and joined with the correct access point. To
check this connection: Right-click on the Local Area Connection icon in the taskbar>
select View Available Wireless Networks. The Connect to Wireless Network screen
will appear. Please make sure you have selected the correct available network, as
shown in the illustrations below.

Troubleshooting

Check that the IP address assigned to the wireless adapter is within the same

IP address range as the access point and gateway. Since the DWL-2700AP has

an IP address of 192.168.0.50, wireless adapters must have an IP address in the
same range, e.g., 192.168.0.x. Each device must have a unique IP address; no two
devices may have the same IP address. The subnet mask must be the same for all
the computers on the network.) To check the IP address assigned to the wireless

adapter, double-click on the Local Area Connection icon in the taskbar > select
the Support tab and the IP address will be displayed. Please refer to Checking

the IP Address in the Networking Basics section of this manual.)

If it is necessary to assign a Static IP Address to the wireless adapter, please refer

to the appropriate section in Networking Basics. If you are entering a DNS Server

address you must also enter the Default Gateway Address. (Remember that if
you have a DHCP capable router, you will not need to assign a static IP address.
See Networking Basics: Assigning a Static IP Address.)

4. What variables may cause my wireless products to lose reception?

D-Link products let you access your network from virtually anywhere you want. However,
the positioning of the products within your environment will affect the wireless range.
Please refer to Installation Considerations in the Wireless Basics section of this
manual for further information about the most advantageous placement of your D-Link
wireless products.

5. Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DWL-2700AP. Try to

keep the antenna at least 6 inches away from the wall or other objects.

If you are using 2.4GHz cordless phones, X-10 equipment or other home security

systems, ceiling fans, and lights, your wireless connection will degrade dramatically
or drop altogether. Try changing the channel on your router, access point and wireless
adapter to a different channel to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that generate RF

noise, like microwaves, monitors, electric motors, etc.

Troubleshooting

6. Why can’t I get a wireless connection?

If you have enabled encryption on the DWL-2700AP, you must also enable encryption
on all wireless clients in order to establish a wireless connection.

Make sure that the SSID on the router and the wireless client are exactly the same.

If they are not, wireless connection will not be established.

Move the DWL-2700AP and the wireless client into the same room and then test

the wireless connection.

Disable all security settings.

Turn off your DWL-2700AP and the client. Turn the DWL-2700AP back on again,

and then turn on the client.

Make sure that all devices are set to Infrastructure mode.

Check that the LED indicators are indicating normal activity. If not, check that the

AC power and Ethernet cables are firmly connected.

Check that the IP address, subnet mask, gateway and DNS settings are correctly

entered for the network.

If you are using 2.4GHz cordless phones, X-10 equipment or other home security

systems, ceiling fans, and lights, your wireless connection will degrade dramatically
or drop altogether. Try changing the channel on your DWL-2700AP, and on all the
devices in your network to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that generate RF

noise, like microwaves, monitors, electric motors, etc.
