Troubleshooting
Check the network cables to be sure they are properly attached to the LAN ports (usually at the back) of each computer. When you cannot access to the Internet, it could be because of loose or defective network cables. Generally, if red or orange lights are flashing from the end of the network cable, this means that data is being transmitted. If only one of the computers on a network cannot detect Internet connection , the network cable attached to that computer is probably not functioning properly. Make sure the drivers for your Ethernet cards are properly installed on your network's computers. If you are not sure about this, double check by clicking the "Start" menu and loading the Control Panel. Click on "System" if you are in "Classic View," and under the "Hardware" tab choose "Device Manager." Check whether there is a "Network Adapter" installed by clicking the plus sign (+) beside it. If you see a yellow exclamation point (!) just beside the "Network Adapter," this means that the driver of the network card is either not properly installed or is corrupted. Check your IP configuration. An IP address is given by the Internet service provider upon installation of the Internet connection. It is a unique set of numbers assigned to a network card for the computer to communicate with other computers in a network. No two computers in a network should have the same IP address. Otherwise, it will cause conflicts that can affect the Internet connection as a whole. In Windows, the most trouble free way to set IP addresses on a computer network is to use the DHCP (Dynamic Host Configuration Protocol) setting. Click "Start," and then "Control Panel." Load "Network Connections," right-click on "Local Area Connection, select "Properties" and under the "General" tab, select "Internet Protocol TCP/IP." Click on "Properties" and select "Obtain IP address automatically" and "Obtain DNS server automatically."Trouble connecting to the Internet may be a result of a defective modem or router. If you are using a router, detach it from the modem and try to see if you can connect to the Internet with a direct line from the modem. If so, the problem lies in the router. If connecting one of your computers directly to the modem does not solve the problem, the problem may lie in a defective modem, or you may be experiencing service provider downtime. Downtime with your Internet connection sometimes happens. Call your Internet service provider for further assistance, or wait until the Internet connection recommences.
