Problem
The computer cannot connect to an Ethernet
LAN.
When a Gigabit Ethernet model computer is
used at a speed of 1000 Mbps, the Ethernet
LAN connection fails or errors occur.
The Wake On LAN (WOL) feature does not
work.
The Wi-Fi feature does not work.
Solution
• Connect the cable from the Ethernet connector to the RJ45
connector of the hub.
• Enable the Ethernet LAN feature in UEFI BIOS.
• Enable the Ethernet LAN adapter.
1. Go to Control Panel and view by large icons or small icons.
2. Click Network and Sharing Center ➙ Change adapter
settings.
3. Right-click the Ethernet LAN adapter icon and click Enable.
• Update or reinstall the Ethernet LAN driver.
• Install all networking software that is necessary for your network
environment. Check with your LAN administrator for the necessary
networking software.
• Set the same duplex for the switch port and the adapter. If you
configured the adapter for full duplex, ensure that the switch port is
also configured for full duplex. Setting a wrong duplex mode might
degrade performance, cause data loss, or result in lost
connections.
