![2. Configuring WiFi Combo Broadband Gateway 2.1. Installation Considerations The WiFi Combo Broadband Gateway allows you access your network using a wireless connection, from virtually anywhere within its operating range. Keep in mind however, that the number, thickness, and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit this range. Typical ranges vary depending on the types of materials used, and background RF (radio frequency) noise in your home or business. To maximize your wireless range, please follow these guidelines: 1. Keep the number of walls and ceilings between the WiFi Combo Broadband Gateway and other network devices to a minimum. Each wall or ceiling can reduce the WiFi Combo Broadband Gateway’s range from 3-90 feet (1-30 meters). Note: The same considerations apply to your broadband EVDO connection. 2. Keep your product aware from electrical devices (such as microwaves, air conditioners, and televisions) that emit large quantities of RFI (Radio Frequency Interference). 2.1.1. Installation Instructions- Get Start Networking Connect this Gateway to Your Network Note: DO NOT connect WiFi Combo Broadband Gateway to power before performing the installation steps below. 1. Connect a USB modem with service to the WiFi Combo Broadband Gateway-- See Picture 2.1 Picture 2.1 Note: The WiFi Combo Broadband Gateway is designed to work with either UMTS or EV-DO and even HSDPA 3G cards that can be used as a modem (support tethered data).

![Open Open system authentication simply consists of two communications. The first is an authentication request by the client that contains the station ID (typically the MAC address). This is followed by an authentication response from the AP/gateway containing a success or failure message. An example of when a failure may occur is if the client's MAC address is explicitly excluded in the AP/gateway configuration. Shared Shared key authentication relies on the fact that both stations taking part in the authentication process have the same "shared" key or passphrase. The shared key is manually set on both the client station and the AP/gateway. Three types of shared key authentication are available today for home or small office WLAN environments. Auto The AP will Select the Open or Shared by the client’s request automatically.

What can I do if my Ethernet cable does not work properly? • First, ensure that there is a solid cable connection between the Ethernet port on the gateway, and your NIC (Network Interface Card). • Second, ensure that the settings on your NIC adapter are “Enabled,” and set to accept an IP address from the DHCP. • If settings appear to be correct, ensure that you are not using a crossover Ethernet cable. Although the WiFi Combo Broadband Gateway is MDI/MDIX compatible, not all NICs are. Therefore, it is recommended that you use a patch cable when possible.
