3. Once your account information is verified, the computers will complete the connection to the network.
This process or “negotiation” can take a few seconds to complete. When the negotiation process is
finished a “Connection Established” dialog box will appear to confirm that you have successfully
connected to the network. You can close this dialog box and proceed to use the Internet.
Connect with EoA Drivers
If your ADSL connection uses the RFC1483 protocol, TCP/IP settings must be configured in your system
in order to connect to your service provider’s network (and ultimately connect to the Internet).
Your ADSL service provider or ISP should give the following information to you:
IP Address . . . . . .
Subnet Mask
Gateway IP Address
DNS Host Name
DNS Domain Name
DNS Server IP Address
Use the information to configure the Modem. Follow the instructions for your operating system.
IP Address Assignment
IP addresses are 32-bit numbers (in the form xxx.xxx.xxx.xxx) from 0.0.0.0 to 255.255.255.255 that
uniquely identify every location on the Internet. In order to communicate with sites on the Internet, your
PC must be assigned a unique IP address.
If your ADSL service provider or ISP uses the Dynamic Host Configuration Protocol (DHCP), your
computer can be assigned an IP address automatically. Checking the
Obtain an IP address
automatically box will enable your PC to receive an IP address automatically from your service provider
through DHCP. This is often referred to as a “dynamic” IP address because it can change over time.
If your ADSL service provider or ISP does not use DHCP, you must manually enter your PC’s IP address.
Your service provider supplies this address. Check the
Use the following IP address box and enter the
IP address of the DNS server in the form xxx.xxx.xxx.xxx (as an example, 172.19.10.91). This is often
referred to as a “static” IP address because it will not change over time.
Subnet Mask
This is a bit mask that determines the extent of the subnet that the PC is on. It is used in combination with
an IP address to define areas of the local network that are logically separated from the rest of the network
(subnets). It is in the form
xxx . xxx . xxx . xxx , where each xxx is a number (represented in decimal) between
0 and 255. The value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and
255.255.255.0 for a Class C network, but custom subnet masks are allowed.
It is recommended that you accept the default Subnet Mask suggested by Windows that corresponds to
the class of IP address you entered above.
Gateway Address
This is the IP address of a network device where packets with a destination address outside the current
subnet should be sent. This is usually the address of a router or a host acting as an IP gateway. If your
network is not part of an intranet, or you do not want the Switch to be accessible outside your local
network, you can leave this field unchanged. Sometimes called the
Default Gateway.
DNS Server Address
The Domain Name System (DNS) was designed by the Internet Engineering Steering Group (IESG) to
allow locations on the Internet to be identified by a name. A DNS server maintains a database of URLs
(Internet location names) and their corresponding IP addresses. When you type a URL in the
Go To
field
of your web browser, your PC will contact a DNS server to determine the corresponding IP address. To
