Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-655.  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 following examples.)
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 recommen\
d the following: 
• Internet Explorer 6.0 or higher 
• Netscape 8 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.

Secton 6 - Troubleshootng
• 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 192.168.0.1. 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. 1492, 14\
82, 1472, 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, 2000, XP and Vista® 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
