Choose “Advanced Setup→QoS”, you can configure the QoS in the next screen. QoS helps to
prioritize data as it enters your modem router. By attaching special identification marks or headers
to incoming packets, QoS determines which queue the packets enter, based priority. This is
useful when there are certain types of data you want to give higher priority, such as voice data

selected network traffic over various technologies.
There are two IP versions: IPv4 and IPv6. If you select IPv4 as IP version, please follow the
configuration below to configure the QoS information (shown in Figure 4-27 ).
