Network cards enable a computer to connect to other computers and devices using Ethernet standards. Different protocols can run on top of Ethernet, though the primary protocol used in most networks is TCP/IP for Internet connectivity. Some Ethernet cards have different automatic power settings available in an attempt to save energy. In some cases, these low-power settings, such as sleep mode, interfere with other devices on the network or the computer itself. You can disable sleep mode on the network card to negate this issue.
