MBA M1 A2337 - Dead Wifi?

Hello everyone !

I have a Macbook Air with quite the unusual issue, I believe I shorted the small parts highlighted in red in the picture below while doing a screen replacement on my unit. (It made funny sparks when the antenna cover slipped....)

Now, the system won't let me activate wifi on the device. I had to use an USB to Ethernet adapter to perform device recovery (It was not booting prior to screen replacement, pink screen and bootloop)

I tried to see if any part was fried on the front side of the logic board but to no avail, I'll try to remove the logic board from the device to check the other side tomorrow

I'm thinking of a logic board repair using a donor board, I'm probably gonna look for a repair shop to do that for me as I'm not that much DIY nor correctly equipped. I'd love your input though regarding the issue, if you already encountered in the past and which lines might be at fault here.

Thanks !

The capacitors that you marked have to do with the LCD backlight circuit, but it's possible another component was damaged. Are you sure the antenna cables are properly connected? Do the antenna connectors on the logic board appear damaged in any way? Are you able to connect to WiFi in Safe Mode? Good luck!

Thanks for the swift answer Zach !

The antenna cables are properly connected although even if they were not, the device should still be able to detect Wi-Fi ; it's the first theory is explored when I encountered the issue ; they have no hardware in them, it's just a long metal antenna.

Antenna board connectors aren't damaged neither, they're the part I hate the most in any disassembly but I made sure to be careful with those.

Lastly, nope, in DFU Mode or Recovery Mode, when I reach the "Activate Mac" screen, Wi-Fi wasn't showing up at all. I had to use an USB C to Ethernet adapter to be able to activate the device and reinstall Mac OS

Total darkness haha

Hi. I have a 2020 M1 Macbook Pro A2338 that I replaced the screen on and ever since the WIFI is off and will not let me switch back on.

The WIFI worked perfectly prior to repair and now the screen and internet work well but only when wired to router.

A wiggle test with continuity meter on WIFI wires revealed a bad connection so I replaced WIFI antenna/vent. No change. I performed a hard reset(all power and battery disconnected for 30 mins) and No change.

I did notice with old antenna the WIFI icon acted like it would look for signal for a split second and give up but since replacement of antenna, it doesnt even try.

I was told its probably a logic board issue. My next step is to send it out for repair.
