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 illustration below.

Troubleshooting (continued)

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-

2000AP 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. 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.

3. Check that the drivers for the network adapters are

installed properly.

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.

The wireless client cannot access the Internet in the Infrastructure

mode.

Troubleshooting (continued)

What variables may cause my wireless products to lose reception?

Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DWL-

2000AP.

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.

Why can’t I get a wireless connection?

If you have enabled Encryption on the DWL-2000AP, 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 or 128bit. Make sure that the encryption

bit level is the same on the Access Point and the Wireless Client.

Move the DWL-2000AP 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.

Troubleshooting (continued)

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

Turn off your DWL-2000AP and the client. Turn the DWL-2000AP 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.

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-2000AP, 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.

I forgot my encryption key.

Reset the DWL-2000AP 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.
