How do i change the
The internal, LAN-IP address is normally set to a default, private number. Linksys routers, for example, use 192.168.1.1 for their internal IP address. D-Link and Netgear routers typically use 192.168.0.1. Some US Robotics routers use 192.168.123.254, and some SMC routers use 192.168.2.1. No matter the brand of router, its default internal IP address should be provided in documentation. Administrators often have the option to change this IP address during router setup. In any case, however, the private LAN-IP address remains fixed once set. It can be viewed from the router's administrative console.
The external, WAN-IP address of the router is set when the router connects to the Internet service provider. This address can also be viewed on the router's administrative console. Alternatively, the WAN-IP address can be found by visiting a Web-based IP address lookup service like http://checkip.dyndns.org/ from any computer on the home LAN.
Another way to identify the public IP addresses of routers, involves executing a ping or traceroute command. From inside a home network, the (DOS) command "ping -r 1" will send a message through the home router that will cause its IP address to be displayed. For example, "ping -r 1 www.yahoo.com" should result in a message like the following displayed on the command prompt:
To change router password
Open your Internet browser, type the address of the router into the URL address bar, and open it. The address is typically in the form of 192.168.X.X. This is the local network address.
Enter the account name and password to open the router setup utility.
Navigate through the setup utility until you find the screen that will let you change the password. You will need to enter the old password to change it.
Decide on a new password that has good security to a hacker. The best password is more than 8 characters and uses both lower case and upper case letters and numbers. Some will allow you to use special characters also. Do not make the password anything that can be found in a dictionary or any date of significance.
Enter the old password in the change password page of the router. When prompted then enter the new password. You will be asked to enter it twice to confirm that the correct password is entered.
Immediately, record the new password in some secure location that you can find if you forget it.
Confirm the password change on the router page and log off the router. To check the information and that the router has been setup correctly with the new password, open the router address in the browser again and login with the new information. If you are able to login, you have successfully changed the password.
