D-Link Router web-based Configurations

Check it out below, maybe you got the same problem !

#1. Why can’t I access the web-based configuration utility?

When entering the IP address of the D-Link router ( 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 6.0 or higher • Netscape 8 or higher • Mozilla 1.7.1 (5.0) or higher • Opera 8.5 or higher • Safari 1.0 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.
  •  Configure your Internet settings:

• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make
sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.

  • Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This should open the 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. Unfortunately 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 When logging in, the username is admin and leave the password box empty.

#3. Why can’t I connect to certain sites or send and receive e-mails when connecting through my router?

If you are having a problem sending or receiving e-mail, or connecting to secure sites such as eBay, banking sites, and Hotmail, we suggest lowering the MTU in increments of ten (Ex. 149, 148, 147, etc).

Note: AOL DSL+ users must use MTU of 1400.
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be another
computer, or a URL.

  • Click on Start and then click Run.
  • Windows ®  95, 98, and Me users type in command (Windows ®  NT, 000, and XP users type in cmd) and press Enter (or click OK).
  • Once the window opens, you’ll need to do a special ping. Use the following syntax:

D-Link Router ping yaooping [url] [-f] [-l] [MTU value]

Example: ping yahoo.com -f -l 1472

You should start at 147 and work your way down by 10 each time. Once you get a reply, go up by  until you get a fragmented packet. Take that value and add 8 to the value to account for the various TCP/IP headers. For example, lets say that 145 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (145+8=1480). Once you find your MTU, you can now configure your router with the proper MTU size.

To change the MTU rate on your router follow the steps below:

  • Open your browser, enter the IP address of your router ( and click OK.
  • Enter your username (admin) and password (blank by default). Click OK to enter the web configuration page for the device.
  • Click on Setup and then click Manual Configure.
  • To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
  • Test your e-mail. If changing the MTU does not resolve the problem, continue changing the MTU in increments of ten.
