Streaming Video From a MacBook With AirPlay

Connect your Apple TV to a television with an HDMI cable for the highest-quality sound and video. If your TV doesn't have an available HDMI port, use a three-component video cable and two-component audio cable. Connect your Apple TV's left and right audio ports to your TV's corresponding inputs and match your Apple TV's green, blue and red video ports to your TV's Y, Pb and Pr ports, respectively.
Connect your Apple TV to the Internet by turning it on and following the on-screen prompts.

Use the on-screen keyboard to enter your password if your network is encrypted. After joining your network, your TV displays a five-digit passcode for pairing with iTunes.
Pair your Apple TV with iTunes by entering the passcode in iTunes on your MacBook. Launch iTunes and press “Command-S” to show the sidebar. Select “Apple TV” in the Devices section and enter the passcode when prompted.

How to Set Up the Internet for the PowerBook G4

Determine what kind of connection you will use to connect to the Internet. You must already have an account set up with an Internet provider. If you plan to use a wireless connection, rather than an Ethernet connection, make sure that your computer has an AirPort Card in it first. Without an AirPort Card inside it, you must use an Ethernet connection. (To determine if you have an AirPort Card, go to 'About This Mac' underneath the Apple menu in the top left corner of your screen and click 'More Info.' If you see 'AirPort' listed underneath 'Network,' then your computer has an AirPort Card installed.) If you're using an Ethernet cable, insert it into the PowerBook's Ethernet port, located on the left side.
Open 'System Preferences,' which is by default located on the Dock. It is also located in the Applications folder on the hard drive (which is titled 'Macintosh HD').
Click on 'Network.'
Click 'Assist me...' then 'Assistant.'
Give your connection a name, or just use the default name provided, and click 'Continue.'
Select the type of Internet connection you have (wireless, DSL or cable--it's DSL if your modem is connected to a telephone wire; it's cable if the modem is connected to a cable wire). Click 'Continue.'
Select the wireless connection that you want to connect to from the list, if you're connecting wirelessly, and enter your password, if required, then click 'Continue'; your computer will automatically connect to the wireless account, and you're done. If you are using an Ethernet cable to connect, click 'Continue' on the next page. Once you're back on the network page, select the network location you just created in the 'Location' tab, and click 'Apply.' If needed, a pop-up will ask for your username and password, and will finish the connection.

How to Improve the Wi

Click the 'AirPort' icon and select 'Turn Wi-Fi Off.' Wait five to 10 seconds, then select 'Turn Wi-Fi On' to reset your wireless adapter. If you leave the MacBook Air's Wi-Fi adapter on for several hours or even days, it becomes overloaded with information and may need to be restarted.
Select the name of an encrypted wireless network with a password you know from the 'AirPort' menu. Although connecting to an unencrypted network requires less effort since you don't need to input a password, using unencrypted networks places you at greater risk for a slow connection due to an excessive number of users.
Connect to a different network if the one you usually use is slow or completely inactive. If another network works on your MacBook Air, even if you don't plan to use it regularly, it shows that the problem is with the connection and not the MacBook Air.
Sit as close as possible to the router for the wireless connection you use. The less distance the signal has to travel, the higher quality it is. This optimizes the speed and consistency of the Internet on the MacBook Air.
