It may take 20-30 seconds to connect to the wireless network. If the connection fails,
please verify that the WPA-PSK settings are correct. The WPA-PSK passphrase must be
exactly the same as on the wireless router.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DWR-921. Read the following descriptions
if you are having problems.
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on the Internet or have to be
connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to
connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 6 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect
to a different port on the device if possible. If the computer is turned off, the link light may not be on.
• Disable any Internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall,
and Windows
®
XP firewall may block access to the configuration pages. Check the help files included with your firewall software for more information
on disabling or configuring it.

login page for your the web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait about 30 seconds and try accessing
the configuration. If you have multiple computers, try connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Please note that this process will change all your settings back to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the button
down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30 seconds to access the router. The default
IP address is 192.168.0.1, and the default username is
admin
and the password should be left blank.

Tips
Here are a few things to keep in mind when installing a wireless network.
Centralize your Router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access
point as high as possible in the room, so the signal gets dispersed throughout your home. If you have a two-story home, you may need a repeater
to boost the signal and extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This would
significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let you unauthorized users connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature
on the router. Refer to “Wireless Settings” on page 22 for detailed information on how to set up wireless security.
