Authentication means making sure that something is what it claims to be. E.g., in online banking, you want to make sure that the remote computer is actually your bank, and not someone pretending to be your bank. The purpose of 802.1x is to accept or reject users who want full access to a network using 802.1x. It is a security protocol that works with 802.11 wireless networks such as 802.11g and 802.11b, as well as with wired devices.
All NETGEAR ProSafe Layer 2 and Layer 3 switches support this authentication.
NETGEAR access points with full WPA (WPA Enterprise) support 802.1x, e.g., WG302, FWG114P and
Details of 802.1x Authentication
The main parts of 802.1x Authentication are:
A supplicant, a client end user, which wants to be authenticated.
An authenticator (an access point or a switch), which is a "go between", acting as proxy for the end user, and restricting the end user's communication with the authentication server.
An authentication server (usually a RADIUS server), which decides whether to accept the end user's request for full network access.
In a wireless network, 802.1x is used by an access point to implement WPA. In order to connect to the access point, a wireless client must first be authenticated using WPA.
In a wired network, switches use 802.1x in a wired network to implement port-based authentication. Before a switch forwards packets through a port, the attached devices must be authenticated. After the end user logs off, the virtual port being using is changed back to the unauthorized state.
A benefit of 802.1x is the switches and the access points themselves do not need to know how to authenticate the client. All they do is pass the authentication information between the client and the authentication server. The authentication server handles the actual verification of the client’s credentials. This lets 802.1x support many authentication methods, from simple user name and password, to hardware token, challenge and response, and digital certificates.
802.1x uses EAP (Extensible Authentication Protocol) to facilitate communication from the supplicant to the authenticator and from the authenticator to the authentication server.
EAP supports various authentication methods. As a user seeking authentication, you just need to use a method supported by the authentication server. As an administrator, you need to select which methods your server will use. Selection is beyond the scope of this article (and outside the scope of free NETGEAR support), however, the material in the Microsoft article will give administrators a solid grounding. Read More ( )

To physically set up the router:
- Remove any cables connecting the modem to the PC.
- Connect the router to the modem: Plug one end of an Ethernet cable to the modem and the other end into the isolated port on the router. The isolated port is yellow or slightly set apart from the rest of the router ports.
- Connect the router to the PC: Plug one end of the Ethernet cable into the PC's Ethernet port, then the other end into any one of the four LAN ports on the router. If there are stickers blocking the LAN ports, remove them.
- Plug in the router's power adapter and check the Power
light to ensure that the router is on.
Note : Older Netgear routers and gateways shipped with an installation CD. Newer router models do not ship with a CD.
Netgear does not replace lost or broken installation CDs, because the management software built into the routers and gateways has a Setup Wizard that serves the same function. There is no need to download anything to replace the CD - everything you need is in your router. This is true even if :
- The CD that shipped with the router has been lost or cannot be read, or
- Errors occur when running the configuration program, or
- The router is not connected to a computer using the Windows operating system.
- Connect your router to a computer by plugging one end of an Ethernet Cable into any of the four LAN ports on the back of your router.

Note: The URL changes by the product model. You can sometimes find the login URL and default login information on a sticker on the bottom or back of the router.
- Enter the username (admin) and password. By default, the password is password or 1234 (for older router models) unless it has already been changed.
- To install your router, simply click on the "Setup Wizard" link at the top of the left-hand navigation menu once you are logged into your router, and follow the displayed instructions.
- If you are familiar with networking, instead of using the setup wizard, you can use the menu to access the various setting screens and apply the settings that you want manually.
