HP 280 G2 User Manual

Network status link light never ashes.
NOTE: The network status light is supposed to ash when there is network activity.
Cause Solution
No active network is detected. Check cabling and network equipment for proper connection.
Network controller is not set up properly. Check for the device status within Windows, such as Device
Manager for driver load and the Network Connections applet
within Windows for link status.
To access Device Manager in Windows 7, click Start, select Control
Panel, and then select Device Manager.
To access Device Manager in Windows 10, type device
manager in the taskbar search box, and then select Device
Manager from the list of applications.
Network controller is disabled. 1. Run Computer Setup and enable network controller.
2. Enable the network controller in the operating system using
Device Manager.
To access Device Manager in Windows 7, click Start, select
Control Panel, and then select Device Manager.
To access Device Manager in Windows 10, type device
manager in the taskbar search box, and then select Device
Manager from the list of applications.
Network driver is not properly loaded. Reinstall network drivers.
System cannot autosense the network. Disable auto-sensing capabilities and force the system into the
correct operating mode.
Diagnostics reports a failure.
Cause Solution
The cable is not securely connected. Ensure that the cable is securely attached to the network
connector and that the other end of the cable is securely attached
to the correct device.
The cable is attached to the incorrect connector. Ensure that the cable is attached to the correct connector.
There is a problem with the cable or a device at the other end of
the cable.
Ensure that the cable and device at the other end are operating
correctly.
Network controller interrupt is shared with an expansion board. Under the Computer Setup Advanced menu, change the resource
settings for the board.
The network controller is defective. Contact an authorized service provider.
Diagnostics passes, but the computer does not communicate with the network.
Cause Solution
Network drivers are not loaded, or driver parameters do not
match current conguration.
Make sure the network drivers are loaded and that the driver
parameters match the conguration of the network controller.
