Ethernet Mode
Ethernet mode allows you to select the speed of your LAN Ethernet connections. (Configure the
WAN Ethernet interface in the Advanced Setup, Layer 2, ETH Interface screen.) Modes
include—auto, 100 full, 100 half, 10 full and 10 half. If you select auto then the gateway will use
the common mode that all the connected interfaces can operate at.
If the GE WAN port is the Ethernet WAN interface, it may be deleted as an Ethernet WAN
interface, so the port may be used as a LAN port.
