Frequently-Asked Questions
Here are answers to questions our customers frequently ask:
Q What is high-speed cable Internet access?
A 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.
Q How fast is the Motorola SBG1000 Wireless Cable Modem Gateway?
A 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.
Q How many users can one SBG1000 support?
A A single SBG1000 can support up to 253 users, each assigned a unique IP address, on a Class C network.
Q What is Network Address Translation?
A NAT is a technique to translate private IP addresses on your LAN to a single IP address assigned by your
cable service provider that is that is visible to outside users on the Internet.
Q What is IEEE_802.11b?
A IEEE 802.11b is the IEEE wireless network standard.
Q What type of firewall is provided on the SBG1000?
A The SBG1000 provides a stateful-inspection firewall.
Q What wireless security measures are provided on the SBG1000?
A To protect data transmitted over wireless connections, the SBG1000 supports WEP encryption and MAC
access control lists. For information, see “Setting Up the Wireless LAN” on page 71.
Q Why is there no Standby button?
A As a security measure, current Motorola SURFboard cable modems provide a Standby button to temporarily
suspend the Internet connection. Because the SBG1000 firewall provides high security levels while
connected, the Standby button is not required.
Q Can I still watch cable TV while using my Motorola SBG1000 Wireless Cable Modem Gateway?
A Yes, your cable TV line can carry the TV signal while you send and receive information on the Internet.
Q What are CableLabs Certified, DOCSIS, and Euro-DOCSIS?
A 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 SBG1000 is DOCSIS or Euro-DOCSIS certified.
Q If I have an SBG1000, can I still use my old 28.8 Kbps or 56 Kbps modem?
A 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.
