Change hand positions often to avoid fatigue. Some computer users might develop 
discomfort in their hands, wrists, or arms after intensive work without breaks. If you 
begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a 
qualified health specialist.
Chair
An adjustable chair that provides firm, comfortable support is best. Adjust the height 
of the chair so your thighs are horizontal and your feet are flat on the floor. The back of 
the chair should support your lower back (lumbar region). Follow the manufacturer’s 
instructions for adjusting the backrest to fit your body properly.
You might have to raise your chair so that your forearms and hands are at the proper 
angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you 
can use a footrest with adjustable height and tilt to make up for any gap between the 
floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. 
Another option is to use a desk with a keyboard tray that’s lower than the regular 
work surface.

External Mouse
If you use an external mouse, position the mouse at the same height as your keyboard 
and within a comfortable reach.
Built-in Display
Adjust the angle of the display to minimize glare and reflections from overhead lights 
and windows. Do not force the display if you meet resistance. The display is not meant 
to open past 130 degrees.
You can adjust the brightness of the screen when you take the computer from one 
work location to another, or if the lighting in your work area changes.

CConnecting to the Internet
You can use your computer to browse the World 
Wide Web, send email to friends and family, and 
chat in real time over the Internet. Use this 
information to help you connect to the Internet.
When you first start up Mac OS X, Setup Assistant helps you enter your Internet 
configuration information. If you didn’t use Setup Assistant to configure your Internet 
connection, you can use Network Setup Assistant later (see “Using Network Setup 
Assistant to Connect” on page 117). If you choose not to use Network Setup Assistant, 
you can use the information in this appendix to set up your connection manually.
There are four kinds of Internet connections:
ÂHigh-speed DSL or cable modem connection:  Your computer is plugged into a 
special modem you get from an ISP using an Ethernet cable.
ÂWireless connection:  Your computer is connected wirelessly using an AirPort 
Extreme Base Station, AirPort Express, or other 802.11b or 802.11g access point.
ÂLocal area network (LAN):  Your computer is plugged into a LAN using an Ethernet 
cable. This type of connection is usually used in the workplace. 
						

							114 Appendix C   Connecting to the Internet
 
ÂDial-up connection:  Your computer is connected to an external modem that is 
plugged into a phone wall jack using a phone cable.
Before you connect to the Internet:
1Set up an account with an Internet service provider (ISP). 
2Gather the connection information you need from your ISP or network administrator. 
See the next section, “Gathering the Information You Need,” to find out what 
information to get for each type of connection. You can write the information directly 
on the next few pages, and then enter it in Setup Assistant.
If another computer in the same location is already connected to the Internet, you 
might be able to use its settings. 
To find the settings on a Mac OS X computer:
ÂOpen the Network pane of System Preferences.
ÂChoose your connection method from the Show pop-up menu. 
ÂCopy the information for your configuration.
To find the settings on a Windows computer:
The connection information on a Windows computer resides in two places.
ÂTo find the IP address and subnet mask, open the “Network and Internet Connections” 
control panel.
ÂTo find user account information, open the User Accounts control panel.

Troubleshooting Your Connection
If you have trouble with your Internet connection, you can try the steps in this section 
for your type of connection or you can use Network Diagnostics.
To use Network Diagnostics:
1Choose Apple () > System Preferences.
2Click Network and then click “Assist me.”

If Network Diagnostics can’t resolve the problem, there may be a problem with the 
Internet service provider (ISP) you are trying to connect to, with an external device you 
are using to connect to your ISP, or with the server you are trying to access. You can 
also try the following steps.
Cable Modem, DSL Modem, and LAN Internet Connections
If you can’t connect to the Internet using your cable modem, DSL modem, or local area 
network (LAN), see the following instructions. 
Important:  Instructions that refer to modems do not apply to LAN users. LAN users 
may have hubs, switches, routers, or connection pods that cable modem and DSL 
modem users do not. LAN users should contact their network administrator rather than 
an ISP.
Check the cables and power supplies
Make sure all modem cables are firmly plugged in, including the modem power cord, 
the cable from the modem to the computer, and the cable from the modem to the 
wall jack. Check the cables and power supplies to Ethernet hubs and routers.  
						

							120 Appendix C   Connecting to the Internet
 
Turn the modem off and on and reset the modem hardware
Cycle the power on your DSL or cable modem by turning if off for a few minutes and 
then turning it back on. Some ISPs recommend that you unplug the modem’s power 
cord. If your modem has a reset button, you can press it either before or after turning 
the modem off and on again.
PPPoE Connections 
If you are unable to connect to your ISP using PPPoE, first check the cables and power 
supplies, and then turn the modem off and on again to reset the modem hardware. 
Next, check your settings in the Network pane of System Preferences.
To check System Preferences settings:
1Choose Apple () > System Preferences from the menu bar.
2Click Network.
