 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 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. 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, press and hold the the rest
button down for 20-25 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 10.0.0.2. When logging in, the default username is admin and the default password it admin.
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, 1482, 1472, 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 (WindowsR NT, 2000, XP, VistaR, 7, 8.x,
and 10 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
