Overview The SBG1000 combines a SURFboard™ cable modem, IEEE 802.11b wireless access point, router with five-port 10/100Base-T switch, print server, and an advanced firewall into one compact product. It is the perfect networking solution for the home, home office, or small business/enterprise. You can create a custom network to share a single broadband connection, files, printers, and other peripherals like scanners, with or without wires.
Powerful Features in a Single Unit The Motorola SBG1000 Wireless Cable Modem Gateway combines high-speed Internet access, networking, and computer security for a home or small-office local area network (LAN). It provides: • An integrated high-speed SURFboard cable modem for continuous broadband access to the Internet and other online services, with much faster data transfer than traditional dial-up or ISDN modems.
Sample LAN The sample LAN shown in the figure contains the following devices, all protected by the SBG1000 firewall: • A printer connected to the print server through the parallel connection • A PDA connected through the wireless IEEE 802.
Wired Ethernet LAN Each computer on the Ethernet LAN requires an Ethernet network interface card (NIC) and driver software installed. Because the Motorola SBG1000 Wireless Cable Modem Gateway Ethernet ports support autoMDIX, you can use either straight-through or cross-over cable to connect a hub, switch, or computer. Use category 5 cabling for all Ethernet connections. The physical wiring arrangement has no connection to the logical network allocation of IP addresses.
USB Connection You can connect a single PC running Windows® 98, Windows XP™, Windows Me®, or Windows® 2000 to the Motorola SBG1000 Wireless Cable Modem Gateway USB port. For cabling instructions, see “Connecting a PC to the USB Port” Sample USB connection. Caution! Before plugging in the USB cable, be sure the Motorola SBG1000 Wireless Cable Modem Gateway CD-ROM is inserted in the PC CD-ROM drive.
IEEE 802.11b Wireless LAN Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a wireless LAN uses radio signals instead of wires to exchange data. A wireless network eliminates the need for expensive and intrusive wiring to connect computers throughout the home or office. Mobile users can remain connected to the network even when carrying their laptop to different locations in the home or office. Each computer on a wireless LAN requires a wireless adapter.
Security The Motorola SBG1000 Wireless Cable Modem Gateway provides: • A firewall to protect the SBG1000 LAN from undesired attacks over the Internet • Security measures to prevent eavesdropping of wireless data Network Address Translation (NAT) provides some security because the IP addresses of SBG1000 LAN computers are not visible on the Internet. The logical network diagram does not necessarily correspond to the network cabling. A full discussion of network security is beyond the scope of this document.
Virtual Private Networks The SBG1000 allows multiple tunnel VPN pass-through operation to securely connect remote computers over the Internet through the SBG1000. The SBG1000: • Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP) • Is fully interoperable with any IPSec client or gateway and ANX certified IPSec stacks Print Server You can connect a printer to the Motorola SBG1000 Wireless Cable Modem Gateway back panel using a standard DB-25 connector.
Connecting the SBG1000 to the Cable System Allow 5 to 30 minutes the first time you turn on the SBG1000 to find and lock on the appropriate communications channels. 1 Be sure the computer is on and the SBG1000 is unplugged. 2 Connect one end of the coaxial cable to the cable outlet or splitter. 3 Connect the other end of the coaxial cable to the cable connector on the SBG1000. Hand-tighten the connectors to avoid damaging them.
Cabling the Ethernet After connecting to the cable system, you can connect your wired Ethernet. Some samples are shown in “Wired Ethernet LAN” on page. Detailed information about network cabling is beyond the scope of this document. You must install proper drivers for the Ethernet NIC adapter. Obtaining an IP address in Windows 98, Windows 98 SE, or Windows Me You must do the following on each Ethernet client PC running Windows 98, Windows 98 SE, or Windows Me: 1 On the Windows Desktop, click Start.
Connecting a PC to the USB Port You can connect a single PC running Windows 98, Windows XP, Windows Me, or Windows 2000 to the Motorola SBG1000 Wireless Cable Modem Gateway USB port. To connect a PC to the USB port: 1 Connect the USB cable to the USB port on the SBG1000. 2 Connect the other end to the USB port on the computer.
Configuring the SBG1000 Configuring the SBG1000 includes: • Starting the SBG1000 Setup Program • Changing the Default Password • Getting Help • Setting the Firewall Policy For more information about configuration, see “Configuring TCP/IP” , “Setting Up the Wireless LAN”, “Configuring the Print Server” or “Setting Up a USB Driver” For normal operation, you do not need to change most default settings.
Starting the SBG1000 Setup Program 1 On a computer on the LAN, open a web browser. 2 In the Address or Location field, type 192.168.100.1 and press ENTER to display the Login window: 3 Enter the User ID and password and click Log in.

(The default password is “motorola.”) 3 Type the new password in the New Password field.
Resetting the SBG 1000 Reset Button 1 To reset all values to their defaults, hold down the button for more than five seconds. Resetting may take 5 to 30 minutes because the SBG1000 must find and lock on the appropriate communications channels. ** Warning!!! This will reset the SBG 1000 to default settings. All your configurations will be lost and you may need to re-configure your SBG 1000.

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.
