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 900-Based PCI Fast Ethernet

Adapter appears as one of the adapters. If it does not exist,

Windows has not detected the National Semiconductor Fast

Ethernet adapter 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 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 is working.

The Ethernet adapter does not appear to operate in the

100Mbps transmission mode -

„

Make sure the hub you are using supports 100Mbps

operation.

Make sure that your RJ-45 cable meets the 100Base-TX

requirements.

Make sure the Ethernet cable is connected to the hub  

socket that supports 100Base-TX mode. The hub may have

both 100Base-TX and 100Base-T sockets.
