HOW DO I CHANGE THE PASSWORD?

By default, the firewall on it should block all incoming connections from the WAN or internet network port (good thing). Make sure you do two things : 1. Change the default password on the router, and 2. secure your wireless using WPA2 for authentication and AES or TKIP for encryption. Also, rename your SSID to something that doesn't give away that fact that your router is a buffalo. I'm paranoid, so I donot broadcast my SSID...if you are too, then this is a good option.

Routers have a reset button on them just for such an issue. Remember when you use this button the router will be reset back to factory settings. Look on the back of the router, you should see a little hole with the word reset above it. With the router pluged in, press this reset button (you may need a paper clip to get in the hole). When you release this button, the router should look like it has been powered cycled. At this point the router is reset to factory. You will need to set everything up on it, just like you did the first time you took it out of the box.

The default login is user = 'admin' and password = 'password' for the router. Only type what is between the quotes. If you changed and forgot your password, there is a reset button on the unit. Press the button until the power light flickers (about 10 seconds). You should now be able to get in using the default login.

log in to the router by typing http://192.168.11.1 into your browser, the default user name is root leave the password blank. The wireless encryption page is available from Home by selecting Wireless Encryption. Here, you can manually select the type of wireless encryption you'd like to use.

NETGEAR G54 Wireless Router provides high-speed Internet connection and upto 54Mbps (IEEE Standard 802.11g specifications). Generally, it can handle multiple users but the bandwidth is sort of divided amongst the users. So, if there are 5 users, each would get roughly about 10Mbps at an average if all the users are logged-in and require data.
Hence, it is suggested to have minimum users to get better speeds per user

Hope this answers your question!

You can check with "Admin" or no password.

if above are not work, please try to contact with your vendor.

Please be a little more descriptive, this technically isn't even a question but I will do my best to help you. Yes, it does require a password which is specific to your network. Unless you changed your router's password, each router has a different default user and password. for this router, the default user name is admin and password by default is password. I recommend changing these in your web browser first, so others can not access your network or router, hence stealing your internet connection. I hope this helps you out.

Connect to the router by typing
http://www.routerlogin.net in the address bar of a browser.
if it asks for the id and password enter
id = admin
password = admin or password or leave it empty

go to Wireless Settings and Change the Channel using the drop down box. Save the settings.

If you haven't changed it then the defaults are:

Username: root
Password: (blank - the password is blank)

Try to reset the router using a paper clip, then try to re-log in to the router with the IP address, If you are still unable to log in , try log as admin as the username and password as admin or admin on the username and password is password.
