SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual 

The SMCD3GN3 Wireless Cable Modem Gateway can be installed in any location with 
access to the cable network. All of the cables connect to the rear panel of the Gateway for 
better organization and utility. The LED indicators on the front panel are easily visible to 
provide users with information about network activity and status. 

For optimum performance, the location you choose should: 

y 

Be close to a working AC power outlet 

y 

Allow sufficient air flow around the Gateway to keep the device as cool as possible 

y 

Not expose the Gateway to a dusty or wet environment 

y 

Be an elevated location such as a high shelf, keeping the number of walls and ceilings 
between the Gateway and your other devices to a minimum 

y 

Be away from electrical devices that are potential sources of interference, such as ceiling 
fans, home security systems, microwaves, or the base for a cordless phone 

y 

Be away from any large metal surfaces, such as a solid metal door or aluminum studs. 
Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors, 
brick, and concrete can also affect your wireless signal 

Using an Ethernet LAN cable, you can connect the Gateway to a desktop computer, 
notebook, hub, or switch. The SMCD3GN3 Wireless supports auto-MDI/MDIX, so you can 
use either a standard straight-through or crossover Ethernet cable. 

1.  Connect either end of an Ethernet cable to one of the four ETH ports on the rear panel of 

the Gateway (see Figure 3).
