Installing the TCP/IP Protocol
Follow these instructions to install the TCP/IP protocol on one of your PCs
only
after a network card has been successfully installed inside the PC. These
instructions are for Windows 95, Windows 98, and Windows ME. For TCP/IP
setup under Windows NT, see your Windows NT manual.
1. Click the
Start
button. Choose
Settings
and then
Control Panel
.
2. Double-click on the
Network
icon to bring up your Network window.
Select the
Configuration
tab.
3. Click the
Add
button
.
4. Double-click on
Protocol
.
5. Highlight
Microsoft
under the list of manufacturers.
Step Two: Pinging for a Web Address
While the IP address returned above would work as your e-mail server
address, it may not be permanent. IP addresses change all the time. Web
addresses, however, usually don’t. Because of this, you’re likely to have less
problems by configuring your system with web addresses rather than IP
addresses. Follow the instructions below to find the web address assigned to
the IP address you just pinged.
1.
At the DOS command prompt
, type “ping -a 24.53.32.4”, where
24.53.32.4 is the IP address you just pinged. Information such as the fol-
lowing data will be displayed.
C:\>ping -a 24.53.32.4
Pinging mail.msnv3.occa.home.com [24.53.32.4] with
32 bytes of data:
Reply from 24.53.32.4: bytes=32 time<10ms TTL=127
Reply from 24.53.32.4: bytes=32 time<10ms TTL=127
Reply from 24.53.32.4: bytes=32 time<10ms TTL=127
Reply from 24.53.32.4: bytes=32 time<10ms TTL=127
Ping statistics for 24.53.32.4:
Packets: Sent = 4, Received = 4, Lost = 0 (0%
loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum =
0ms, Average =
0ms
2.
Write down the web address returned by the ping command
. (In the
example above: mail.msnv3.occa.home.com.) This web address is the web
address assigned to the IP address you just pinged. While the IP address
of “mail” could change, it is likely that this web address will not.
3.
Replace your ISP’s abbreviated server address
with this extended web
address in the corresponding Internet application (web browser, e-mail
application, etc.).
Once you have replaced the brief server address with the true server address,
your Router should have no problem accessing the Internet through that
Internet application.

Twisted-Pair Cabling
There are different grades, or “categories,” of twisted-pair cabling. Category 5
is the most reliable and most highly recommended. Category 3 is a good sec-
ond choice. Straight-through cables are used for connecting computers to a
hub. Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally,
which allows you to link or connect hubs together with a straight-through cable
instead).
You can buy pre-made Category 5
cables, or cut and crimp your own.
Category 5 cables can be purchased or
crimped as either straight-through or
crossover. Inside a Category 5 cable are
8 thin, color-coded wires inside that run
from one end of the cable to the other.
All 8 wires are used. In a straight-
through cable, wires 1, 2, 3, and 6 at one
end of the cable are also wires 1, 2, 3,
and 6 at the other end. In a crossover
cable, the order of the wires change
from one end to the other: wire 1
becomes 3, and 2 becomes 6. See the
diagrams on the next page for more
detailed
information
on
straight-
through and crossover
cabling.
To determine which wire is wire number 1, hold the cable
so that the end of the plastic RJ-45 tip (the part that goes
into a wall jack first) is facing away from you. Face the clip
down so that the copper side faces up (the springy clip will
now be parallel to the floor).
When looking down on the
copper side, wire 1 will be on the far left.
6. Find and double-click
TCP/IP
in the list to the right (below)
.
7. After a few seconds, the main Network window will appear.
The TCP/IP
Protocol should now be listed.
8. Click the
OK
button. Windows may ask for original Windows installation
files.
Supply
them
as
needed,
e.g.,
D:\win98,
D:\win95,
c:\windows\options\cabs.
9. Windows will ask you to restart the PC. Click the
Yes
button.
The TCP/IP Installation is now complete.
