unable to enable Wi-Fi in Macbook Air M4

I’m using a MacBook Air (M4, 24GB RAM, 512GB SSD) running the latest version of Mac OS.

While working normally, my Mac suddenly restarted and showed this message in the log:


panic(cpu 0 caller 0xfffffe0039e41568): "port enable failed: 0xe00002d6"

@AppleMultiFunctionManager.cpp:1

673


After the restart, the Wi-Fi icon is greyed out and cannot be enabled.

This exact issue happened once before and Apple Service simply reset the internal WiFi network Antenna cable device and wifi started working fine. Later they ran apple server toolkit test and found no issue. 


Has anyone else seen this issue on Apple Silicon (M4) Macs running latest macos?

Is this a known recurring hardware fault, or is there a firmware/software fix planned?


Any guidance from Apple engineering or other users who resolved similar “port enable failed” kernel panics would be appreciated.

Attached a snippet for reference


MacBook Air 13″, macOS 26.0
