If you activate UPnP (Universal Plug and Play) on your router, then PCs in your local network
that have UPnP installed in their operating system can offer their own services on the Inter-
net, and also automatically use services offered on the Internet.

DNS – entering the DNS server
DNS (Domain Name System) is a decentralised database on the Internet that assigns user-
friendly symbolic names (domains) to the public IP addresses for computers and services.
Access to this database requires DNS servers that convert the DNS name into the IP address
when the connection is established to a computer/server. DNS servers are normally pro-
vided automatically by your Internet provider and do not need to be set up additionally.
The DNS server that you enter here will only be used if your provider does not make a DNS
server available.
¤ Open the following Web page: Router Settings ¢ Internet ¢ DNS.
¤ Activate the use of a user-friendly DNS server for your Internet connection by entering
its IP address in the Preferred DNS Server field.
¤ In the Alternate DNS Server field enter the IP address of a server that should be used if the
preferred server is not available.
¤ Click Set to apply the settings.
QoS – setting the Quality of Service, prioritising VoIP
Many communication and multimedia applications require high speed and large band-
widths to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection with limited capacity available.
QoS (Quality of Service) divides this capacity between the different applications and pro-
vides undelayed, continuous data transfer where data packets with higher priority
(e.g. VoIP) are given transmission preference.
¤ Open the following Web page: Router Settings ¢ Internet ¢ QoS.
¤ In the Upstream Rate field indicate the maximum bandwidth for your Internet connection
that should be available for uploads.
¤ Click Set to apply the settings.
