To log in to your D-Link router and change its settings, visit the router's Web interface and log in with the administrative password. You can usually find the interface address and the password on the bottom of the router or in the manual. The most common addresses are 192.168.0.1 and 192.168.1.1, and most D-Link routers either use the password admin or have a blank password by default. If your router also asks for a username, use admin.
Step 1: Log In
Visit the router's interface address, such as 192.168.0.1, in any Web browser on a computer connected to the router. If you plan to make changes to your wireless settings, use a computer with a wired connection to avoid getting disconnected after each change. Enter your password -- or leave the box blank for routers without a password -- and click Log In.
The D-Link interface varies from router to router, but the process works similarly on any model.
If you can't determine your router's interface address, find the default gateway address using ipconfig. Use this address to open the interface.
Step 2: Change Basic Settings
Click Setup and choose a tab such as Internet, Wireless Settings or Network Settings to change basic settings such as your DNS servers, wireless network name or the Wi-Fi password.
On routers with the modern-style interface, find these settings by mousing over Settings and selecting a section such as Internet, Wireless or Network.
Step 3: Change Advanced Settings
Open the Advanced tab for other settings such as port forwarding, filtering and firewall options.
In the modern-style interface, mouse over Features to find these settings.
Step 4: Change Router Management Settings
Open the Tools tab to change settings related to router administration in the Admin section, such as the administrative password, and to view system logs in the Syslog section.
In the modern-style interface, mouse over Management to find sections such as System Admin and System Log.
Step 5: Finish Up
Click Save (or Save Settings) on any page where you make changes. Your router might reboot after some changes, after which you'll need to log in again. When you're done, just close your Web browser to log out.
