Network Adapter / Ethernet Problems

The Ethernet adapter does not work

•Go to [Start > Settings > Control Panel > System > Hardware > Device Manager]. Double-click on Network Adapters and check if Realtek RTL8510EX Family Fast Ethernet NIC appears as one of the adapters. If it does not exist, Windows has not detected the Realtek RTL8510EX Family Fast Ethernet NIC or

the device driver has not been installed properly. If there is a yellow mark or red cross on the network adapter, it may be a device or resource conflict. Replace or update the device driver from the factory CD-ROM disk or consult the Windows manual on how to solve the resource conflict problem.

•Make sure the physical connections on both ends of the cable are good.

•The hub or concentrator may not be working properly. Check to see if other workstations connected to the same hub or concentrator are working.

The Ethernet adapter does not appear to operate in the 100/1000Mbps transmission mode

•Make sure the hub you are using supports 100/1000Mbps operation.

•Make sure that your RJ-45 cable meets the 100/1000Base-TX requirements.

•Make sure the Ethernet cable is connected to the hub socket that supports 100/1000Base-TX mode. The hub may have both 100Base-TX and 1000Base- T sockets.
