  How Do I Troubleshoot My Internet Service Installation?
  
 
How Do I Troubleshoot My Internet Service Installation? 
I cannot connect to  the Internet 
  Verify that the plug to your residentia l gateway AC power is properly inserted 
into an electrical outlet. 
   Verify that your residential gateway AC power cord is not plugged into an 
electrical outlet that is controlled by a  wall switch. If a wall switch controls the 
electrical outlet, make sure the switch is in the  ON position. 
   Verify that the  POWER and CABLE  indicator lights on the front panel of your 
residential gateway are illuminated. 
   Verify that the indicator lights on yo ur router or other network connection 
equipment are illuminated 
   Verify that all cables are properly conne cted, and that you are using the correct 
cables. 
   Verify that your cable service is active  and that it supports two-way service. 
   Verify that TCP/IP is properly installed  and configured on all devices if you are 
using the Ethernet connections. 
   Verify that you have called your servic e provider and given them the serial 
number and MAC address of your residential gateway. 
   If you are using a cable signal splitter so  that you can connect the cable signal to 
other devices, remove the splitter and reco nnect the cable so that the residential 
gateway is connected directly to the main  cable input. If the residential gateway 
now functions properly, the cable signal  splitter may be defective and may need 
to be replaced. 
   For best performance over an Ethernet connect, your PC should be equipped 
with a 10/100BASE-T network interface card. 
 
My residential gateway does no t recognize the cable network 
The residential gateway works with a standard, 75-ohm, RF coaxial cable. If you are 
using a different cable, your residential  gateway will not function properly. Contact 
your service provider to determine  if you are using the correct cable.

Frequently Asked Questions   
Frequently Asked Questions 
Q. How Many Ethernet Network Devices Can I Connect?  
A.  Your residential gateway uses has an integrated Dynamic Host Configuration 
Protocol (DHCP) to automatically issue  IP addresses to devices as they are 
connected to your home network.   
The theoretical maximum number of device s supported by your residential gateway 
is 253.  These addresses are assigned to all connected devices, wired (Ethernet) as 
well as wireless.  Typically, the number  of devices connected should be a much 
lower number.  
The residential gateway can support severa l Ethernet devices by connecting them 
directly to the Ethernet ports on the back  panel or using external multi-port Ethernet 
switches (purchased separately).  
Contact your service provider for more  information on the maximum number of 
Ethernet network devices to connect to your  residential gateway to maintain optimal 
network performance. 
 
Q. What Are the Wiring Requirements for Ethernet Networking?  
A. A number of factors can impact the prac tical limit of the network. Although the 
residential gateway is designed to support  several Ethernet network devices, it is 
important to view the characteristics of  the entire network and not just each 
individual node.  
The theoretical distance between two 10/100BASE-T CAT-5 Ethernet hubs is 382 feet 
(100 meters). Contact your service provider  or consult the documentation for your 
Ethernet network devices for more information. 
Note:  We recommend that you use CAT-5 Ethernet cables. 
 
Q. Where Is the Best Location for My Ethernet Network Devices?  
A. You should work with your service prov ider to choose the best location for your 
Ethernet network devices. Cons ider these recommendations: 
   Location of two-way cable outlets 
   Distance of the Ethernet network devices from the residential gateway 
   Location of computers and other equipment from AC power outlets 
   Ease of running Ethernet cable  to the Ethernet network devices 
 
Q. What Are the Requirements for Wireless Networking?  
A. It is important to view the characterist ics of the entire network and not just each 
individual node. The theoretical distance  between wireless network devices is 100 
feet inside of a building, and 300 feet outdoors.

  Frequently Asked Questions
   
A number of factors can impact the practi cal limit of the network. Contact your 
service provider or consult the documentat ion for your wireless network devices for 
more information. 
 
Q. Where Is the Best Location for My Wireless Network Devices?  
A. You can use a large variety of wirele ss network devices with your residential 
gateway. These include computers, PDAs, et c. On the wireless network, all devices 
impact the characteristics of the network,  because each device transmits a wireless 
signal. 
Contact your service provid er or consult the documentation for your wireless 
network device for more information on  selecting the appropriate wireless network 
devices for your home or office network. 
You should work with your service provider  to choose the best location for your 
wireless network devices. Consider these recommendations: 
   Distance from the residential gateway to the wireless network devices. 
   Do not place the residential gateway near  metallic surfaces that may block the 
wireless communications path. Wireless  communication is “line-of-sight” 
through non-metallic walls. However, the  more structures (walls) the signal 
must pass through, the weaker the received signal. 
   Do not place wireless network devices ne ar a microwave oven. When operating, 
microwave ovens can interfere  with wireless transmissions. 
   Do not place your wireless network devi ces near 2.4 GHz wireless telephones 
because these telephones may also ca use interference with your wireless 
network.
