•Check if other PCs work. If they do, ensure that your workstations IP settings are correct (IP address, Subnet Mask, Default gateway and DNS)
•If the PCs are configured correctly, but still not working, check the Cable/DSL Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)
•If the Cable/DSL Router is configured correctly, check your Internet connection (DSL/Cable modem, etc.) to see that it is working correctly.
•Manually configure the TCP/IP with a DNS address provided by your ISP.

router automatically enables.
Where is the Cable/DSL Router installed on the network? In a typical environ- ment, the Router is installed between the Cable/DSL Modem and the LAN. Plug the Cable/DSL Router into the Cable/DSL Modem’s Ethernet port.
Does the Cable/DSL Router support IPX or AppleTalk? No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used from LAN to LAN connections, but those protocols cannot connect from WAN to LAN.
Does the WAN connection of the Cable/DSL Router support 100Mb Ethernet? Because of the speed limitations of broadband Internet connections, the Cable/DSL Router’s current hardware design supports 10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over the
What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Cable/DSL Router to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP.
