MacBook Air M4(Unable to enable Wi-Fi - permanently greyed out) - “port enable failed: 0xe00002d6”

Problem details and system configuration

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

While working, my Mac suddenly restarted and showed the following log message (Full log attached in the link text of this post) -

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

@AppleMultiFunctionManager.cpp:1673

After the restart, The Wi-Fi icon is greyed out and cannot be enabled. Rebooting in SafeMode did not help.

This exact issue happened once before last week, and Apple Service simply reset the Wifi network Antenna cable post which it started working fine. They also ran apple server toolkit and did not find any issue.

Has anyone else seen this issue?

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.

Refer to the attached text for the complete error log.

MacBook Air 13″, macOS 26.0
