Network problems
Problem Solution
ThinkSmart Core cannot connect to an
Ethernet LAN.
• Connect the cable from the Ethernet connector to the RJ45
connector of ThinkSmart Core.
• 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 ThinkSmart
Core 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).
My ThinkSmart Core is a Gigabit Ethernet
model, but it cannot be connected to the
network at 1000 Mbps, but at only 100 Mbps. • Try another cable.
• Set the link partner to auto-negotiate.
• Set the switch to be 802.3ab-compliant (gigabit over copper).
