| Apr 8, 2023 at 21:01 | comment | added | wengen | By two different adapters, you mean Bluetooth and WiFi ? What do the 3.3 V and 1.5 V mean in this linked picture ? Is one responsible for the WiFi and the other for the Bluetooth ? Yes, obviously if one adapter is “dead”, the other could still work even if they are on the same card. I don’t have any isopropyl alcohol at my home currently, but I have a can of compressed air. Is there any risk to spray with compressed air the connector on the logic board that connects to the WiFi cable ? | |
| Apr 8, 2023 at 17:52 | comment | added | Allan | Keep in mind that this adapter is basically a 2-in-1; two different adapters on a single card. To illustrate this, have a look at the pin config for mini PCIe. You’ll see that there are multiple 3.3V and 1.5V power sources. It’s possible to kill one and only affect “half” the adapter | |
| Apr 8, 2023 at 17:29 | comment | added | wengen | I will try that, thank you. I don’t remember that there was ever any contact between liquid and the computer. In September 2021, I had to replace the keyboard, so I took out most computer parts, but there was never any liquid near the computer, and there was definitely never any liquid damage, I’m quite sure about that. The worst that could have happened maybe is some finger fat or dust that got in contact with it | |

| Apr 8, 2023 at 16:04 | comment | added | Allan | You mght have an issue wth the logic board. Maje sure the bus connector (where the AirPort card plugs into the logic board) is clean and shiny. Get some 91% isopropyl and a nylon bristle brush (Harbour Freight) and clean it. Make sure it’s dry before reconnecting the card and especially before powering on | |
| Apr 8, 2023 at 15:27 | comment | added | wengen | Under System Information -> Wi-Fi, it only shows the software part, not the hardware. So it’s like here (the hardware is not shown) discussions.apple.com/thread/254743022 | |
| Apr 8, 2023 at 14:55 | comment | added | Allan | Not working as in the hardware is not detected or detected and there is no signal? | |
| Apr 8, 2023 at 12:56 | comment | added | wengen | Hey Allan ! This morning, I received the new WiFi card. An hour ago, I just replaced the card but the problem is still the same: bluetooth works but not WiFi. Do you maybe know what else it could possibly be ? apple.stackexchange.com/questions/458274/… | |

| Mar 30, 2023 at 18:06 | comment | added | Allan | Both situations are plausible. It could be sheer coincidence that one failed at the same time as the other or the short could have damaged a component. . I’ve personally repaired MacBooks for what I thought was routine only to have another, totally unrelated component fail. It just happens. | |

| Mar 30, 2023 at 17:57 | comment | added | wengen | Isn't it highly unlikely that both the WiFi cable and Airport card stop working at the same time ? Or did a problem in one of them cause a problem in the other ? Like there was an issue with the Airport card that then caused the WiFi cable to break ? This seems just so strange, like it's really a coincidence that both components broke at the same time. So you think that replacing the WiFi cable is not enough and that somehow the Airport card was also damaged at exactly the same time ? Could something else that is unrelated to both the card and cable cause the issue ? | |
