1 Overview The CBN CG7486E Wireless Gateway is the worldwide most compact EuroDOCSIS 3.0 Gateway with stylish and elegant outlook, designed for your home, home office, or small business/enterprise. It can be used in households with one or more computers capable of wireless connectivity for remote access to the wireless gateway. This user guide provides product overview and setup information for the CG7486E.
An IEEE 802.11n/ac wireless access point to enable laptop users to remain connected while moving around the home or small office or to connect desktop computers without installing network wiring. Depending on distance, wireless connection speeds can vary. CG7486E wireless function supports Wi-Fi 2.4G/5G dual-band mode.
Sample Wireless Network Connections (CG7486E model shown) Your maximum wireless operation distance depends on the type of materials through which the signal must pass and the location of your CG7486E and clients (stations). CBN cannot guarantee wireless operation for all supported distances in all environments. Note: To get better wireless coverage, please put your CG7486E wireless gateway VERTICALLY ONLY Wired Ethernet LAN You can easily connect any PC with an Ethernet cable to the CG7486E Ethernet port.
Sample Ethernet to Computer Connection (CG7486E model shown) A wired Ethernet LAN with more than two computers requires one or more hubs, switches, or routers. You can: Connect a hub or switch to any Ethernet port on the CG7486E. Use Ethernet hubs, switches, or routers to connect up to any combination of 253 computers and wireless clients to the CG7486E. More detailed information on Ethernet cabling is beyond the scope of this document.
Front Panel The CG7486E front panel contains indicator lights and the Wi-Fi / WPS button which is used to configure Wi-Fi Protected Security (WPS) on compatible clients connected to the CG7486E network.

1 Item Description LAN 1 2 3 4 Use any Ethernet port to connect an Ethernet-equipped computer, hub, bridge, or switch using an RJ-45 cable. Activity LED - Green LED defines the activity of the Ethernet connector. When LED is ON, this indicates that there is no data traffic and a connection is stabilized. When LED is FLASHING, this indicates that there is data being transmitted upstream or downstream. When LED is OFF, this indicates that the unit is not powered or there is no Ethernet connection.
2 Getting Started Inside the Box Before you install the CG7486E Wireless Gateway, verify that the following items are included in the box with the CG7486E: Item Description Power Adapter Connect the CG7486E to an AC electrical outlet WiFi Sticker Card For user placing the WiFi SSID/Password information for 2.4GHz and 5GHz for future use. Ethernet Cable Connect the CG7486E to PC or Notebook You must have the latest service packs and patches installed on your computer for your operating system.
Before You Begin Take the following precautions before installing the CG7486E: Postpone installation until there is no risk of thunderstorm or lightning activity in the area. To avoid potential shock, always unplug the power cord from the wall outlet or other power source before disconnecting it from the CG7486E rear panel. To prevent overheating the CG7486E, do not block the ventilation holes on the sides of the unit. Do not open the unit. Refer all service to your Internet Service provider.
Next, avoid physical obstructions whenever possible. Any barriers along the "line of sight" between client and base station will degrade a Wi-Fi radio signal. Plaster or brick walls tend to have the most negative impact, but really any obstruction including cabinets or furniture will weaken the signal to some degree. Obstructions tend to reside closer to floor level; therefore, some folks prefer to install their wireless access point / router on or near the ceiling.
Connecting the CG7486E Before starting, be sure the computer is turned on and the CG7486E power cord is unplugged. 1. Connect one end of the coaxial cable to the cable outlet or splitter. 2. Connect the other end of the coaxial cable to the Cable connector on the CG7486E. Hand-tighten the connectors to avoid damaging them. 3. Plug the power cord into the Power port on the CG7486E. 4. Plug the other end of the power cord into an electrical wall outlet. This automatically powers on the gateway.
