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: Six options to choose from: Auto, 10M half-duplex, 10M full-
duplex, 100M half-duplex, 100M full-duplex and Disable. 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 0-5 are used to specify the priority
of the packet.
This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it
will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is
enabled, the router’s Ethernet switch will check the 2
nd
octet of each IP packet. If the
value in the TOS field matches the checked values in the table (0 to 63), this packet will
be treated as high priority.
