The first thing that you will need to do is connect the basics of your Netgear router. Take the power cord out of the box and plug in the router so that it can start running. Once it has power, add an ethernet cable connecting the router to the modem and another cable connecting to a computer.
Once the connections are in place, you can start the setup process.
You may have a Netgear installation CD that came with the router. Feel free to put that in and use it alongside these instructions. The most important thing is that it should have the relevant drivers on it. This can make the whole process a little more straightforward, although it isn't vital that you have the Smart Wizard CD. The router's management software also has a tab for "Smart Wizard," which is the exact same thing and should help you configure the router properly once you make a physical connection to it.
To establish a connection to your Netgear router, open up an Internet browser and go to 192.168.1.1, 192.168.1.0 or routerlogin.net/.com. If you can't make a connection, then make sure that your cables are connected. If they are, then it may just not have detected the connection. Unplug the router, count to five and then plug it back in to restart it. It should result in a connection. Try again and see if you can connect through the browser.
You will need to log in to your router before you can configure the settings. This should just be a default password, unless it's a used router. If you are using a used router, then you will need to reset it. There should be a small pinhole that you can stick a pencil or needle into to trigger the reset. Hold the button inside down for a few seconds until the lights flash and it resets to default settings.
The default password should just be "password." All Netgear routers use the username "admin." The username actually can't be changed, so this should always work. If "password" doesn't work, then try "1234." This should let you login to your Netgear wireless router. At this point you just need to secure your connection and configure your settings.
