Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-100.  Read the following 
descriptions  if  you  are  having  problems.    (The  examples  below  are  illustrated  in  Windows®  XP.    If  you  have  a  different  operating 
system, the screenshots on your computer will look similar to the follow\
ing examples.)
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (19.168.0.1 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 6.0 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 c\
omputer 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 i\
t.

• 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. C\
lick 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 19.168.0.1. 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 emails when connecting through my router? 
If you are having a problem sending or receiving email, 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). 
 
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: 
 ping [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 fo\
r the network we’re working with (145+8=1480). 
Once you find your MTU, you can now configure your router with the p\
roper MTU size. 
To change the MTU rate on your router follow the steps below: 
• Open your browser, enter the IP address of your router (19.168.0.1) 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 the Home tab and click the WAN button.  
• To change the MTU enter the number in the MTU field and click the Apply button to save your settings. 
•  Test  your  email.  If  changing  the  MTU  does  not  resolve  the  problem,  continue  changing  the  MTU  in  increments  of 
ten.
