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).

2.1.2. Establish WiFi Connection
If you selected either WEP or WPA-PSK encryption, ensure these settings match your
WiFi adapter settings.
WiFi and encryption settings must match for access to the WiFi Combo Broadband
Gateway Configuration Menu, and the Internet. Please refer to your WiFi adapter
documentation for additional information.
