2 Connecting to your network and line
LAN ports LAN1 to LAN4 on the SAR715PVW router are the type
designed to be connected directly to the port on a PC LAN card or
to any type of switch/hub port (i.e. either ‘normal’ or ‘uplink’) using a
standard cat5 LAN cable.
Use the supplied RJ11 phone cable to connect from the ADSL
socket on your router to your ADSL phone socket.
Connect the power jack from the power supply to the power socket
on the router and then plug the power supply into a suitable UK
power socket: The green POWER LED on the front of the router
should light up.
If you want to do configuration via the Command Line Interface
using Telnet then you can connect using the standard user name
‘admin’ and password ‘admin’ and the default IP address of the
router is 192.168.0.1. If you want to use CLI mode via the serial port
then you’ll need to connect a 9pin serial cable to the RS232
connector on the back of the router (a ‘normal’ modem, serial cable
is required which can be purchased from your supplier if needed).
Port settings are 9600,8,1,n,no flowcontrol.

Alternatively a more user friendly configuration method is to
use the built in http interface. To do this all you need to do to
be able to do is access the router through your web browser
running on any computer.

Solwise SAR715PVW ADSL Ethernet Router User’s Guide Chapter 3. Setting up TCP/IP on your computer
15
3 Setting up TCP/IP on your computer
You first of all need to check the TCP/IP settings of your computer.
Please note that the author is assuming you are using MS Windows
(Win9x or 2K/XP) or Mac OS10; please make appropriate
allowances if using another operating system or platform such as
Linux. The default IP address of the SAR router is 192.168.0.1 on
subnet mask 255.255.255.0. In simple terms this means that, in
order for your computer to talk to the router, their IP address should
be in the range from 192.168.0.2 to 192.168.0.254. If you already
use TCP as your default network protocol and you don’t use IP
settings in the required range then you will have to either
permanently alter the settings of your computers to suite or change
the default address of the router. If you wish to alter the settings of
all your computers to suite then it is probably best to ask the person
in charge of your network set-up to do this for you. If you want to
alter the router then you will have to temporarily change the settings
for your PC.
3.1 Installing TCP protocol on your PC
Win9x Win2K/XP
Go to Start/Settings/Control Panel/Network....
If you already see a line showing TCP/IP protocol such as
the example shown above then you can skip this section.
Otherwise click on Add, then select Protocol and then click
on Add.. again. Then on the Select Network Protocol
screen select Microsoft/TCP/IP...
Go to Start/Settings/Network and Dialup Connections...
Click on ‘Local Area Connection’.

Chapter 3. Setting up TCP/IP on your computer Solwise SAR715PVW ADSL Ethernet Router User’s Guide
16
Click on OK and Windows will then add the protocol to your network set-
up.
Then on Properties..
If you already see a line showing TCP/IP protocol such as
the example shown above then you can skip this section.
Otherwise click on Install, then select Protocol and then
click on Add.
Then on the Select Network Protocol screen select
Microsoft/TCP/IP...
Click on OK and Windows will then add the protocol to
your network set-up.

Solwise SAR715PVW ADSL Ethernet Router User’s Guide Chapter 3. Setting up TCP/IP on your computer
17
3.2 Configuring TCP/IP Protocol for your PC
Go to Start/Settings/Control Panel/Network....
Scroll down the list of network settings until you find the
entry showing TCP/IP. There may be several such entries
(see example); the one you need is the entry associated
with your network card. Select it and then click on
Properties:
The first screen shows the IP Address for your PC. As
already explained, you need to ensure that each PC on
your LAN has an IP address which is both unique and
within the subnet range of the routers address e.g. in the
range 192.168.0.2 to 192.168.0.254 (assuming default IP
address for the router).
Next, for each PC you must enter a Gateway address. This
is the address of the router and tells your PC where to
send internet TCP requests:
Go to your local network settings (Start/Settings/Network
and Dialup Connections/Local Area
Connection/Properties).
Scroll down the list of network settings until you find the
entry showing TCP/IP. Select it and then click on
Properties:
As already explained, you need to ensure that each PC on
your LAN has an IP address which is both unique and
within the subnet range of the routers address e.g. in the
range 192.168.0.2 to 192.168.0.254 (assuming default IP
address for the router).
Now you need to enter the address of the router as the
default gateway.

Chapter 3. Setting up TCP/IP on your computer Solwise SAR715PVW ADSL Ethernet Router User’s Guide
18
Finally you must set-up DNS Configuration on each PC:
Each PC MUST have the address for DNS entered in it’s
TCP setting. If your PC doesn’t have a DNS setting then it
will not be able to find any internet sites so it’s important
that you have this set correctly!
On the DNS Configuration screen you must Enable DNS
and then enter a Host name; this can be anything you like
– just a made up name will do!
Now you need to enter the DNS address.
Each PC MUST have the address for DNS entered in it’s
TCP setting. If your PC doesn’t have a DNS setting then it
will not be able to find any internet sites so it’s important
that you have this set correctly!
On the main TCP/IP Properties screen select ‘Use the
following DNS server addresses’.
Now you need to enter an address for the ‘Preferred DNS’.
Ideally you should get the DNS address to use from your
ISP (a list showing some of the common ISP DNS
addresses is given below). However, if you don’t know the
ISPs’ DNS address then you can temporarily use the
address 212.50.160.100.
Enter the DNS address for the preferred DNS (as shown
above).
Finally click on OK, then OK and then Close. The new
TCP/IP settings should take immediate effect.,
That’s all there is to the basic set-up.

Solwise SAR715PVW ADSL Ethernet Router User’s Guide Chapter 3. Setting up TCP/IP on your computer
19
Ideally you should get the DNS address to use from your
ISP (a list of common addresses is given later). However, if
you don’t know the ISPs’ DNS address then you can
temporarily use the address 212.50.160.100 or
1212.50.160.28. You need to ‘add’ the DNS address to the
DNS list.
Finally click on OK and then OK from the main Network
menu.
Windows will now install the revised network settings;
please note that your original Windows installation CD
might be required. You should then reboot your PC.
That’s all there is to the basic set-up.
3.3 Setting up TCP/IP protocol on your Mac
Configuration of the router is done using your web browser but first
of all you need to ensure that the IP settings on computer are
correctly set to enable you to talk with the router. The default IP
address of the Asus router is 192.168.0.1 with netmask
255.255.255.0. This means your computers and other network
resources should have IP address’s in the range 192.168.0.2 to
192.168.0.254. First of all go to the Network set-up on your Mac:

Chapter 3. Setting up TCP/IP on your computer Solwise SAR715PVW ADSL Ethernet Router User’s Guide
20
Enter a suitable IP address (e.g. 192.168.0.2) and the netmask as
shown above and click on Apply Now.
Now enter the IP address of the router in ‘Router’ box.
You also need to enter an address for your ‘Domain Name Server’.
