Hello you have not entered the routers name.
Basicly it`s just to visit the routers homepage for downloading a user manual.
Here is some homepages that tells how:http://pcsupport.about.com/od/fixtheproblem/f/change-router-password.htm
You will probably have to hold the reset button from 10 to 30 seconds
depending on your brand of router. If you hold it for too short a time
it will simply reset the router but won't revert back to its factory
default settings. On some routers you may have to use a pin or thumbtack
to press the button if it is recessed inside the router.
2. Connect a computer to one of your router's Ethernet ports (but not the one that says WAN)
Most router's have a web browser-accessible administrator page that
you must log in to in order to access the router's configuration
settings. Some routers disable administration via wireless, so you will
need to ensure that you are connected to the router via an Ethernet
cable before attempting to access the router's configuration page.
3. In the browser address bar, enter the IP address of your router's administration interface
Most routers have what is called a non-routable internal IP address
such as 192.168.1.1 or 10.0.0.1. This is an internal address that cannot
be accessed from the internet.
Here are the standard admin interface addresses used by some of the
more popular wireless router manufactures. You may have to consult your
specific router's manual for the correct address. The following list is
some of the default IP addresses based on my research and may not be
accurate for your specific make or model:
Linksys - 192.168.1.1 or 192.168.0.1
DLink - 192.168.0.1 or 10.0.0.1
Apple - 10.0.1.1
ASUS - 192.168.1.1
Buffalo - 192.168.11.1
Netgear - 192.168.0.1 or 192.168.0.227
4. Enter the default administrator login name (usually "admin") followed by the default administrator password.
You can locate the the default admin name and password for your
specific router by checking the manufacturer's website or by Googling
"Default Admin Password" followed by your router's brand name and model.
5. Click on the "Admin" page from your router's configuration page and create a strong password
Be sure you enter a strong complex password for your router's admin
password. If you ever looe this password you will have to repeat the
If you didn't lose you router password but just don't know how to
change it, you can skip steps 1 and 2 and enter the admin user name and
password that you have into step 4. This will allow you to change your
wireless router's password without wiping out all your other router's
