Reference Manual for the Model HR314 802.11a Hi-Speed Wireless Router When a PC accesses a resource by its descriptive name, it first contacts a DNS server to obtain the IP address of the resource.

IP Configuration by DHCP When an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each PC on the network can automatically obtain this configuration information. A device on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP server stores a list or pool of IP addresses, along with other information (such as gateway and DNS addresses) that it may assign to the other devices on the network. The HR314 has the capacity to act as a DHCP server. The HR314 also functions as a DHCP client when connecting to the ISP. The router can automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway address if the ISP provides this information by DHCP. Wireless Networking The Model HR314 802.11a Hi-Speed Wireless Router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11a standard for wireless LANs (WLANs).

Network and Routing Basics
When a PC accesses a resource by its descriptive name, it first contacts a DNS server to obtain the
IP address of the resource. The PC sends the desired message using the IP address. Many large
organizations, such as ISPs, maintain their own DNS servers and allow their customers to use the
servers to look up addresses.
IP Configuration by DHCP
When an IP-based local area network is installed, each PC must be configured with an IP address.
If the PCs need to access the Internet, they should also be configured with a gateway address and
one or more DNS server addresses. As an alternative to manual configuration, there is a method by
which each PC on the network can automatically obtain this configuration information. A device
on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP
server stores a list or pool of IP addresses, along with other information (such as gateway and DNS
addresses) that it may assign to the other devices on the network. The HR314 has the capacity to
act as a DHCP server.
The HR314 also functions as a DHCP client when connecting to the ISP. The router can
automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway address if
the ISP provides this information by DHCP.

transmitted in the unlicensed radio spectrum at 5GHz. The maximum data rate for the wireless link
is 72 Mbps, but it will automatically back down to 6 Mbps when the radio signal is weak or when
