Internet Tutorials


Controlling AirPort Network Access with Time Limits

If you own an AirPort base station, you can use the Timed Access feature to control the days and times when users access the Internet. This could come in handy in a variety of situations. For example, if you own a cafe and provide free wi-fi access, you can configure the AirPort to block all access to the Internet when your business is closed. And if you have children, you can set time limits for specific devices in your home.

Setting DHCP Reservations on Your AirPort

In a previous tutorial, you learned how to set a static IP address in Mac OS X to create a permanent, private IP address for your Mac that doesn't change from one day to the next. But if you own an AirPort Extreme, AirPort Express, or Time Capsule base station, you can use something called DHCP reservations to do essentially the same thing.

Creating a Dedicated 5GHz AirPort Network

AirPort base stations released after 2009 are capable of operating over both 2.4GHz and 5GHz bands simultaneously. That means that when you connect a Mac, iPhone, or iPad to an AirPort's wireless network, it will automatically select and use one of the bands for the best speed, consistency, and range.

How to Password Protect an AirPort's Settings

Whether you operate a guest network on your AirPort or simply use it to provide wireless access to the people in your home or workplace, you should ensure that your AirPort base station's settings are protected with a strong password. Doing so will prevent users connected to the AirPort network from modifying the base station's settings with the AirPort Utility application. The base station's password is usually specified when setting up the AirPort, but it can be changed at any time.

How to Create a Guest Network with an AirPort

Did you know that your AirPort base station is capable of creating two separate wi-fi networks? By enabling the guest network feature, you can create a second network specifically for guests or - since guest wi-fi networks can be open or protected with a password - authorized users. Creating a guest wi-fi network with your AirPort is easy and takes only a few minutes. This tutorial shows you how to do it.



Why Create a Guest Wi-Fi Network?

Tell Apple's Mail When to Receive Messages

Apple's free Mail application is included with every Mac. Just add an account and you'll be sending and receiving email in no time.

Drowning in Email? Enough is Enough!

How to Move Your Email to Another Mac

If you use Apple's Mail application, there will probably come a time when you'll want to move your email messages and email account to another Mac. Maybe you just purchased a new Mac. Or maybe you've kept your personal email at work, and you now want to move those emails and that account to your Mac at home. Fortunately, there's an easy way to move your mail!

How to Find the Best DNS Servers

We've previously discussed how to change the DNS servers on your Mac, iPad, and AirPort Extreme. But how do you know which DNS servers to use? There are dozens of free DNS providers, and all of them claim to offer the best service. Don't worry. In this tutorial, we'll show you how to find the best DNS servers, no matter where you're located or which device you're using.

Why Can't Anyone Tell Me Which DNS Servers to Use?

How to Change Your iPad's DNS Servers

Just like in Mac OS X, you can change the DNS servers on your iPad. This can significantly speed up Safari and other iPad apps that use the Internet. For a general introduction to DNS, and to learn why you would want to change the DNS servers on your iPad, see How to Change Your Mac's DNS Servers.

Change an AirPort Extreme's DNS Servers

If you own an AirPort Extreme and use it as a router, you can specify default DNS servers for all of the devices connected to your wireless network. This is a great way to enforce enterprise network policies using OpenDNS, which allows you to implement security and filtering controls.
