SymptomSolution(s)

You are running Windows NT. After you connect the Ethernet Adapter, your computer cannot obtain a valid IP address.

The Ethernet Adapter configuration settings may not be compatible with the network. If they are not, and your Windows NT computer is set up to obtain its IP address from a DHCP server, the Ethernet Adapter is unable to associate with the network to obtain the IP address.

To work around this, set a static IP address on your computer. Then set the Ethernet Adapter configuration to match the network. When the Ethernet Adapter is able to associate, reset your computer to obtain its IP address from the DHCP server. If the Ethernet Adapter should also obtain its IP settings from the DHCP server, make sure this is configured properly on the IP Network page and applied just before ending the session.

Access to the Ethernet Adapter through Ethernet is blocked because of incorrect settings in the Access Control List.

Restore the Ethernet Adapter to factory default settings (see “Restoring the Ethernet Adapter to Factory Defaults” on page 45). The factory default setting for the Access Control List is disabled. After the factory default settings are restored, the Ethernet Adapter can be accessed through Ethernet again.

CAUTION: Disconnecting the Ethernet Adapter ends the network association. To avoid possible data loss, exit all networking applications on connected devices before you disconnect the Ethernet Adapter.

VORSICHT: Wird die Verbindung des Ethernet-Adapters getrennt, wird damit auch die Netzwerkverbindung unterbrochen. Zur Vermeidung von eventuellen Datenverlusten müssen alle Netzwerkanwendungen auf verbundenen Geräten beendet werden, bevor die Verbindung des Ethernet-Adapters getrennt wird.

1Unplug the Ethernet Adapter Ethernet cable from the hub or other device.
