How to Share your Mac internet with your wireless devices

Share your Mac internet with your wireless devices

Many hotels, virtual offices, and other locations only provide a single wired Ethernet connection. If you need to share one internet connection with multiple devices, you can use your Mac as a sort of Wi-Fi hotspot or access point for other devices to connect to.

This will let other devices, even non-Mac computers, and mobile devices, access the internet through your Mac. The way it works is very similar to the built-in Internet Connection Sharing feature in Windows.

Note that this process shares your internet connection with other computers and mobile devices, so you'll need an Ethernet network adapter and a wireless adapter on your Mac. You can use a wireless USB adapter to add Wi-Fi capability to your Mac if necessary.


How to Share Mac Internet Connection

 1. Open System Preferences and select Sharing.
 2. Select Internet Sharing from the list on the left.
 3. Use the drop-down menu to select where to share your connection, such as Ethernet to share your wired connection.
 4. Under that, choose how other devices will connect to your Mac, such as AirPort (or even Ethernet).
 1. Note: Read any prompted "warnings" if you get them, and click OK if you agree with them.
 5. From the left pane, place a checkmark in the box next to Internet Sharing.
 6. When you see a prompt about sharing your Mac's internet connection, simply press Start.

Internet Sharing Tips From Mac

  * If you are using AirPort, enable wireless encryption by clicking the AirPort Options... button and checking the option to enable encryption. Even though it only uses the very bad WEP protocol, WEP encryption (choosing a 128-bit key) is better than nothing.
  * You can change the channel for your wireless network to minimize conflicts with other networks, and also choose a unique name for your network.
* If your Mac host computer goes to sleep or shuts down, all connected clients will be disconnected and no new clients will be able to find the connection until the computer is turned on again.
   * You can easily stop sharing your internet connection by unchecking the box next to "Internet Sharing" in Step 5.
