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 RTL8139/810x Family Fast
Ethernet NIC (or Realtek RTL8169/8110 Family Gigabit NIC)
appears as one of the adapters. If it does not exist, Windows
has not detected the 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 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
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.
