Chapter 4: Configuration
Port Setting
This section allows you to configure the settings for the router’s Ethernet ports to solve
some of the compatibility problems that may be encountered while connecting to the
Internet, as well allowing users to tweak the performance of their network.
Port # Connection Type: Five options to choose from: Auto, 10M half-duplex, 10M full-
duplex, 100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility
problems with legacy Ethernet devices, and you can configure different types to solve
compatibility issues. The default is Auto, which users should keep unless there are
specific problems with PCs not being able to access your LAN.
IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2 nd octet of
an IP packet. Bits 6-7 of this octet are reserved and bit 0-2 are used to specify the priority
(precedence) of the packet, and bits 3-5 are specified the delay, throughput and reliability.
This feature uses bits 0-2 to classify the packet’s priority. If the packet is high priority, it will
flow first. Therefore, when this feature is enabled, the router’s Ethernet switch will check
the 2nd octet of each IP packet. If the value in the Precedence of TOS field matches the
checked values in the table (0 to 7), this packet will be treated as high priority.
