Network problems

Note: The Wi-Fi and Bluetooth features are optional.

Problem

Solution

The computer cannot connect to an Ethernet LAN.

  • 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.

When a Gigabit Ethernet model computer is used at a speed of 1000 Mbps, the Ethernet LAN connection fails or errors occur.

Connect the network cable to the Ethernet connector using Category 5 wiring and a 100 BASE-T hub/switch (not 100 BASE-X).
