Troubleshooting (continued)

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 illustration 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-2200AP 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.

Check to make sure that the router in your network is functioning properly by

pinging it. If the router is not functioning properly, it will not connect to the

Internet. If you need to find out how to ping network devices, please refer to

Checking the Wireless Connection by pinging

in the

Networking Basics

section of this manual.

Check to make sure that the DNS server in your network is functioning properly

by pinging it. If the DNS server is not functioning properly, you may be unable

to access the Internet. Typically, your ISP (Internet Service Provider) will be

able to give you the DNS server information.

You may be using different network adapters than those illustrated here, but this procedure

will remain the same, regardless of the type of network adapters you are using.

5.

Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DWL-2200AP.

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-2200AP, you must also enable encryption on

all wireless clients in order to establish a wireless connection.

Make sure that the SSID on the access point and the wireless client are exactly

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

The encryption settings are: 64-, 128-, or 152-bit. Make sure that the encryption

bit level is the same on the access point and the wireless client.

±

±

Move the DWL-2200AP and the wireless client into the same room and then test

the wireless connection.

±

Disable all security settings. (WEP, MAC Address Control)

±

When deploying several access points and wireless devices, please make sure

that access points in close proximity do not have overlapping channels. Nearby

access points should be assigned channels that are at least 4 channels apart to

prevent interference. For example, with a group of 3 access points you could

assign the first to channel 1, the second to channel 6, and the third to channel 11.

±

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.

Why can’t I get a wireless connection? (continued)

Turn off your DWL-2200AP and the client. Turn the DWL-2200AP back on again,

and then turn on the client.

±

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

AC power and Ethernet cables are firmly connected.

Make sure that all devices are set to

Infrastructure

mode.

±

Check that the IP address, subnet mask, and gateway 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-2200AP,

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.

7.

I forgot my encryption key.

Reset the DWL-2200AP to its factory default settings and restore the other

devices on your network to their default settings. You may do this by pressing

the Reset button on the back of the unit. You will lose the current configuration

settings.
