Frequently-Asked Questions
Here are answers to questions our customers frequently ask:
What is high-speed cable Internet access?
Cable Internet access uses cable television wires instead of telephone lines to connect to the Internet. It is 
extremely fast and does not tie up telephone lines for incoming or outgoing calls and faxes.
How fast is the Motorola SURFboard Cable Modem Gateway SBG940?
Cable modems offer Internet access at speeds up to 100 times faster than a traditional phone modem. You 
can experience speeds of over 1,000 Kbps. Due to network condition such as traffic volume and the speed of 
the sites you visit, actual speed may vary. Many network and other factors can affect download speeds.
How many users can one SBG940 support?
A single SBG940 can support up to 253 users, each assigned a unique IP address, on a Class C network.
What is Network Address Translation?
NAT is a technique to translate private IP addresses on your LAN to a single IP address assigned by your 
cable provider that is that is visible to outside users on the Internet.
What are IEEE 802.11g and IEEE 802.11b?
They are IEEE wireless network standards.
What type of firewall is provided on the SBG940?
The SBG940 provides 
 firewall. For more information, see “
What wireless security measures are provided on the SBG940?
To protect data transmitted over wireless connections, the SBG940 supports 
 encryption and 
 access control lists. For information, see “
Why is there no Standby button?
As a security measure, current Motorola SURFboard cable modems provide a Standby button to temporarily 
suspend the Internet connection. Because enabling the SBG940 
 provides high security levels while 
connected, the Standby button is not required.
Can I still watch cable TV while using my SBG940?
Yes, your cable TV line can carry the TV signal while you send and receive information on the Internet.
What are CableLabs Certified, DOCSIS, and Euro-DOCSIS?
CableLabs Certified, DOCSIS, and Euro-DOCSIS are the industry standards for high-speed data distribution 
over cable television system networks. They are intended to ensure that all compliant cable modems 
interface with all compliant cable systems. Your SBG940 is DOCSIS or Euro-DOCSIS certified.
If I have an SBG940, can I still use my old 28.8 Kbps or 56 Kbps modem?
Yes you can. However, once you’ve experienced the speed of cable Internet access, you’ll never again want 
to wait for traditional dial-up services.
