Protect your privacy and personal information by protecting the D-Link wireless network with a strong password. If you don't secure your Wi-Fi network, an attacker can connect to it and launch a man-in-the-middle attack. To prevent others from changing the router's security settings, change its administrator password as well.
A strong password contains at least eight characters -- uppercase and lowercase letters, numbers and special characters.
Changing the Wi-Fi Password
Open the Web browser, type 192.168.0.1 into the address bar and press Enter to access the D-Link Web interface. Select Admin from the User Name drop-down box and type the password into the Password field. The default password is admin. Click Log In.
Some routers don't come with a password, so you must leave the field blank.
If you can't access the interface, find the correct IP address by using the Command Prompt.
- Press Windows-X to expand the Power User menu in Windows 8 and 8.1 and select Command Prompt from the menu.
- Type ipconfig into the Command Prompt window and press Enter to view information about your network.
- Find the IP address of the router in the Default Gateway section and use it in the Web browser to open the D-Link Web interface.
Select Wireless Settings from the left pane of the Setup tab and select a security mode from the Security Mode drop-down box.
- WPA2 is the latest and most secure wireless security protocol.
- WPA is an older protocol that is still relatively secure.
- WEP is the least secure protocol; don't use WEP when you can select WPA or WPA2.
Select a cipher type from the Cipher Type box -- use the new AES cipher whenever possible.
Type the password into the Passphrase and Confirmed Passphrase fields and then click Save Settings to protect the wireless network.
Devices connected to the wireless network are disconnected. Type the new password when reconnecting the devices.
Changing the Administrator Password
Change the administrator password to prevent people from connecting to the router and changing its security settings. An attacker can lock you out of your own D-Link router if you don't change the password.
Select the Tools tab after connecting to the Web interface and then type a new password into the New Password and Confirm Password fields in the Administrator section. To change the username, type a new name into the Login Name field.
On some routers, such as the D-Link D624, the Web interface is a bit different. To change the wireless password, select the Wireless sub-tab on the Home tab, select a security protocol from the Authentication section and then type the password into the Passphrase and Confirmed Passphrase fields. Click Apply to apply the new settings.
You can find more information about the default IP address, username and password by consulting the user guide that came with the device. Alternatively, you can find user guides on the D-Link Support website.
During a man-in-the-middle attack, an attacker can steal your bank details, usernames, passwords and other sensitive information.
