Here’s how to create an admin account without knowing the current administrator password.
This is nothing new to people familiar with unix, and can’t really be classified as a “hack”, but it’s an easy way to make an admin account without a password. This particular method is used if you, for some reason, can’t get into your account at all, for example: you lost MAC Admin password and you account is protected with FileVault. This process basically forces your computer to re-run setup, which is what you see when you setup a new Mac.
This process will take about 5-10 minutes. If you have a password, or WEP code for your network or internet, be sure to have that at hand.

You can reset your router.

1. Press the reset button [the tiny button on the back of your router, marked Reset] for 10 seconds. You can use a small object, such as a paper clip to hold down the button.
Do not power off the unit while the router is being reset.
The unit should now reboot, and once the WLAN light stops blinking the router should be reset.

2. Open up your Web browser and enter 192.168.0.1 in the address bar.
3. For the login, enter admin as the ID and leave the password blank.

The router has now been reset. Follow the steps in Securing D-Link DI-524 Wireless Router to secure your router.
