Troubleshooting
This chapter provides solutions to problems that can occur during the installation and
operation of the DWL-AG700AP 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-AG700AP Wireless Access Point.
1. The computer used to configure the DWL-AG700AP cannot access the
configuration menu.
±
Check that the
Ethernet LED
on the DWL-AG700AP 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.
±
Check that the
IP address
is in the same range and subnet as the DWL-AG700AP.
Please see
Checking the IP Address
in Windows XP
in the
Networking Basics
section of this manual.
Note:
The IP address of the DWL-AG700AP 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-AG700AP is responding. Go to
Start
>
Run
>Type
Command
>Type
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-AG700AP.

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.
±
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-AG700AP 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-AG700AP. 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.
6.
Why can’t I get a wireless connection?
If you have enabled encryption on the DWL-AG700AP, 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-AG700AP and the wireless client into the same room and then test
the wireless connection.
±
Disable all security settings.
±
Turn off your DWL-AG700AP and the client. Turn the DWL-AG700AP 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

channel on your DWL-AG700AP, and on all the
devices in your network to avoid interference.
