Using the Configuration Menu (continued)
Advanced > Performance > 802.11g (continued)
CTS Mode-
CTS (Clear To Send) is a function used to minimize collisions
among wireless devices on a wireless local area network (LAN).
CTS will make sure the wireless network is clear before a wireless client attempts to send wireless data. Enabling CTS will
add overhead and may lower wireless throughput.
None-
CTS is typically used in a pure 802.11g environment.
If CTS is set to “None” in a mixed mode environment
populated by 802.11b clients, wireless collisions may
occur frequently.
Always- CTS will always be used to make sure the wireless
LAN is clear before sending data.
Auto-
CTS will monitor the wireless network and automatically decide whether to implement CTS based on
the amount of traffic and collisions that occurs on
the wireless network.
802.11g only mode- Select this mode to restrict your network to only those devices
that employ the 802.11g standard. Enabling this mode will ensure that you maintain the highest connectivity rate, unhampered
by any connection to an 802.11b device.

Remote Management
Remote Management allows the DI-774 to be configured from the Internet by a web
browser. A username and password is still required to access the Web-Management
interface. In general, only a member of your network can browse the built-in web pages
to perform “Administrator” tasks. This feature enables you to perform “Administrator”
tasks from the remote (Internet) host.
IP Address: Internet IP Address of the computer that has access to the Router. It is not
recommended that you set the IP Address to * (star), because this allows any Internet
IP Address to access the Router, which could result in a loss of security for your network.
If you elect to enable Remote Management, make sure to enter the IP Address of the
remote computer allowed to configure the DI-774.
Port: For security purposes, select a separate port number used to access the Router.
(The following is an example only; you may use a different port number.)
Example: http://x.x.x.x:8080 where x.x.x.x is the WAN IP Address of the Router and
8080 is the port used for the Web-Management interface.

Assigning a Static IP Address in Windows XP/2000
Note: Residential Gateways/Broadband Routers will automatically assign IP Addresses to the computers on the network, using DHCP (Dynamic Host Configuration Protocol) technology. If you are using a DHCP-capable Gateway/Router you
will not need to assign Static IP Addresses.
If you are not using a DHCP capable Gateway/Router, or you need to assign a Static IP
Address, please follow these instructions:

Troubleshooting
This Chapter provides solutions to problems that can occur during the installation and
operation of the DI-774 Wireless Broadband Router. 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 DI-774 Wireless Broadband Router.
1.The computer used to configure the DI-774 cannot access the
Configuration menu.
! Check that the Ethernet LED on the DI-774 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
DI-774. Please see Checking the IP Address in Windows XP in
the Networking Basics section of this manual.
Note: The IP Address of the DI-774 is 192.168.0.1. 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 DI-774 is responding. Go to
Start>Run>Type Command>Type ping 192.168.0.1. 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 DI-774.

Troubleshooting
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.
default
! 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
DI-774 has an IP Address of 192.168.0.1, 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.)

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

Troubleshooting
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 DI-774. 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?
To establish a wireless connection, while enabling Encryption on the DI-774, you must
also enable encryption on the wireless client.
! For 802.11a, the Encryption settings are: 64, 128 or 152 bit. Make sure that the
encryption bit level is the same on the Router and the Wireless Client.
! For 802.11g, the Encryption settings are: 64, 128, or 152 bit. Make sure that the
encryption bit level is the same on the Router and the Wireless Client.
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. Please note that there are two
separate SSIDs for 802.11a and 802.11g. The default SSID for both 802.11a and 802.11g
is default.

Troubleshooting
7. Resetting the DI-774 to Factory Default Settings
After you have tried other methods for troubleshooting your network, you may
choose to Reset the DI-774 to the factory default settings. Remember that DLink Air Xpert products network together, out of the box, at the factory default
settings.
To hard-reset the D-Link Air Xpert DI-774 to Factory Default Settings, please do the
following:
! Locate the Reset button on the back of the DI-774
! Use a paper clip to press the Reset button
! Hold for about 10 seconds and then release
! After the DI-774 reboots (this may take a few minutes) it will
be reset to the factory Default settings
