5.2 Configuring a PC Connected by USB Port
5.2.1 Connecting a Computer to the USB Port by a USB cable
If you use the ADSL router
s USB port to connect to a PC, you must install the provided
USB driver on the PC. The driver enables Ethernet-over-USB communication with the
ADSL router.
5.2.2 Installing the USB Driver
Ensure that the USB function of your PC is OK.
The Microsoft Windows 98, 98 SE, ME, 2000, and XP support this driver. The following
installation instruction is based on Windows XP; you may refer to it when operating on
other operating systems.
1. Insert the driver CD to your CDROM.
The CD shipped with the ADSL router contains the USB drivers. Insert it into your PC
s
CDROM.
2. Plug the USB cable from the device into the USB port of the PC.
The USB cable provided has a flat connector on one end (called Type A) and a square
connector on the other (Type B). Connect the flat connector to your PC and the square
connector to the ADSL router.

5.2.3 Configuring IP Properties on PC Connected by USB Port
After the USB driver installation is complete, you must configure the PC so that its IP
properties place it in the same subnet as the ADSL router
s USB port. There are two
ways to do this:
Configure the ADSL router so that it assigns an appropriate IP address to the PC.
If you want to use this automatic assignment feature called DHCP server, you
must configure the PC to accept dynamically assigned IP information. Follow the
instructions in
5.1
Configuring Ethernet PCs
for the operating system installed
on your PC.
If you want to assign a static IP address to the PC, follow the instructions
described in
5.1.7
Assigning Static Internet Information to Your PCs
and use the
following information:
In the Network Connections window, be sure to select the icon that corresponds to your
new USB connection (not the one that corresponds to your Ethernet NIC). When you
display properties for the icon, the following text should appear in the Connect Using
text box:
Aolynk USB Remote NDIS Network Device
The USB port on the ADSL router is preconfigured with these properties:
USB port IP address:
192.168.1.1
USB port subnet mask:
255.255.255.0
Therefore, your PC must be configured as follows:
IP address:
192.168.1.n where n is a
number from 2 to 254 that does not conflict
with the DHCP address range.
Subnet mask:
255.255.255.0

6.1 IP Addresses
&
Note:
This section refers only to IP addresses for IPv4 (version 4 of the Internet Protocol).
IPv6 addresses are not covered.
This section assumes basic knowledge of binary numbers, bits, and bytes.
IP addresses, the Internet version of telephone numbers, are used to identify individual
nodes (computers or devices) on the Internet. Every IP address contains four numbers,
each from 0 to 255 and separated by dots (periods), e.g. 20.56.0.211. These numbers
are called, from left to right, field1, field2, field3, and field4.
This style of writing IP addresses as decimal numbers separated by dots is called
dotted decimal notation
. The IP address 20.56.0.211 is read "twenty dot fifty-six dot
zero dot two-eleven."
6.1.1 Structure of an IP Address
IP addresses have a hierarchical design similar to that of telephone numbers. For
example, a 7-digit telephone number starts with a 3-digit prefix that identifies a group of
thousands of telephone lines, and ends with four digits that identify one specific line in
that group.
Similarly, IP addresses contain two kinds of information.
Network ID:
Identifies a particular network within the Internet or intranet
Host ID
: Identifies a particular computer or device on the network
The first part of every IP address contains the network ID, and the rest of the address
contains the host ID. The length of the network ID depends on the network's
class
(refer
to the following section). Table 7-1 shows the structure of an IP address.
