Network Connection Problems
There may be a network connection problem if the LED on the card’s bracket does not light, or if
you cannot access any network resources from the computer. Check the following items before
contacting SMC Technical Support.
• Be sure you are using FACTORY-made Category 5 cable for 100Mbps connections and
that the length of any cable does not exceed 100m (328ft).
• Inspect all network cables and connections. Make sure the network cable is securely
attached to the card’s connector.
• Make sure the correct network card driver is installed for your operating system. If
necessary, try reinstalling the driver.
• Make sure the computer and other network devices are receiving power. If you suspect a
power outlet to be faulty, plug another device into it to verify that it is working.
• If the network card’s speed or duplex mode has been configured manually, check that it
matches that of the attached network device port. Note that it is recommended to set
the card to Auto-Negotiation or Auto-Sense. In some cases, the hub or switch may not
support this properly. Try going into the Network Properties of the card, and set the
speed to 10BaseT (10Mb half duplex).
• The port on the network device that the card is attached to may be defective. Try using
another port on the device.
• If you cannot access the Internet, be sure to check with the ISP for further instructions
once the drivers for the SMC1244TX are installed properly.
