All Apple iMac desktop computers come with a built-in wireless networking card, referred to as an Airport card. Use an Apple Airport wireless router to set up a local network in your home or office and share a single Internet connection across multiple computers. If your iMac computer is registering a low Airport signal or no signal at all, there are several steps you can take to improve the signal and increase the wireless card's range.

    Quick fixes

  1. 1

    Clear away any large objects surrounding your Airport wireless router to limit interference with the wireless signal and increase the wireless range.

  2. 2

    Move your Airport router to different locations in your home or office to improve the wireless signal.

  3. 3

    Disable or turn off other wireless devices that could be causing interference, such as cordless phones, Bluetooth devices or other routers.

    Advanced troubleshooting

  1. 1

    Navigate to the "Utilities" folder on your iMac and double-click on the "Airport Utility" icon. A window will open, and your iMac will begin scanning for nearby wireless routers.

  2. 2

    Double-click on your Airport wireless router from the list located on the left side of the window.

  3. 3

    Go to the "Airport" tab at the top of the window.

  4. 4

    Open the drop-down menu next to "Channel" and choose a different number from the one currently set, which can reduce interference with other devices and improve your iMac's wireless range.

  5. 5

    Go to "Wireless Options" at the top of the window.

  6. 6

    Choose "100%" from the "Transmit Power" drop-down menu. This setting will ensure that your iMac and Airport router are using the full extent of their wireless range.

  7. 7

    Press the "Update" button to save the changes to your wireless configuration.
