Apple AirPort Extreme Model A1143 Wi-Fi Antenna Replacement

简介

The three WiFi antenna are very fragile and sensitive. Be very careful when removing and replacing them, as touching the replacement antenna can cause them to not function at peak efficiency. The old antenna do not require the same care, though you should avoid bending or forcing to remove the antenna because they could snap and ruin the device. Also be careful with the metal attached to the antenna can bend and cause the metal casing to not fit back together with the other pieces.

  1. Apple AirPort Extreme Model A1143 Wi-Fi Antenna Replacement, Back Pad: 步骤 1 中的图像 1，1

    • The back pad is held in with glue so use caution when removing to prevent tearing. Low heat may be used to help remove the pad.

    • Slowly peel off the rubber pad on the bottom of the device. Start from one corner and peel with your fingers. Use heat if necessary until pad is completely removed.

    This is where you would use the opening tool. It’s the perfect tool to lift the rubber base around the metal lip and then pull with your fingers.

    I have found it easier to lift from the side with the Ethernet ports. When putting back together watch that the three WI-FI antennas don’t get snagged against the case as your putting back.

    Take care to remove the small pieces of metallic tape between the case and the spring copper comb earthing strips in the case.

    If you do not, it is a real fiddle to put them back in place latter (the tape will pull them out of the case ground steps)

    PS: I believe the onboard power converter is bust: the board sings when power turned on. So to trash it goes.

    (external power supply is good), swapped with another to test).

    Sad…

Thanks for the guide.

Pulled mine apart to examine the battery inside. It measured above 3.1 volts - even though it has been in use since June 2008 (about 9 years).

Holes will be punched for access to the 5 screws so the rubber pad does not have to be removed if it needs to be opened in the future.

I may see about buying a new Ac adapter to power this Airport Extreme since that is probably why the status light on the front did not illuminate.
