How to Fix Mac Wi-Fi Drops After Sleep in macOS Tahoe 26.2

Symptom: After your Mac wakes from sleep, Wi-Fi is dropped and won't reconnect on its own. Or, the Mac won't wake until you press Return several times or force-restart. Reported on M1, M2, M3, and M4 MacBooks running macOS Tahoe 26.2.

TL;DR fix

Open Terminal and run sudo ifconfig en0 down, wait 5 seconds, then sudo ifconfig en0 up — this restarts the Wi-Fi interface and clears the suspended state. Then in System Settings → Battery → Options (or Displays → Advanced on desktops) turn off Wake for network access to stop the sleep/wake loop. If the issue returns after a reboot, see Fix 3 for the SMC-level reset path.

Why this happens

macOS Tahoe has introduced new "Power Nap" behaviors that can cause the network interface (en0) to stay in a "suspended" state after the system wakes. This is often caused by a conflict between the system's power management and the Wi-Fi hardware's firmware.

Fix 1: Reset the Wi-Fi Interface (Free)

A simple toggle in the menu bar isn't enough; you need to restart the network daemon.

Open Terminal

Go to Applications > Utilities > Terminal.

Restart Network Services

Type: sudo ifconfig en0 down
Wait 5 seconds.
Type: sudo ifconfig en0 up

Renew DHCP Lease

Go to System Settings > Wi-Fi > Details... > TCP/IP.
Click Renew DHCP Lease.

Fix 2: Adjust Sleep Settings (Free)

If your Mac won't wake up properly, you may need to disable "Wake for Network Access."

Open System Settings

Go to Displays > Advanced...

Disable Network Wake

Turn off "Wake for network access" (or "Power Nap" on older models).

Battery Settings

If on a MacBook, go to Battery > Options and set "Wake for network access" to Never.

Fix 3: The Automated Reliability Path

When power management sensors are out of sync.

Persistent wake/sleep issues are often a symptom of a deeper "System Management" error that native settings can't reach.

Recommended Tool: CleanMyMac X

- Maintenance Scripts: The "Flush DNS Cache" and "Run Maintenance Scripts" modules in CleanMyMac X reset the internal network configurations that get stuck during sleep transitions.

- Optimization: Identifying background apps that are "Preventing Sleep" (like stuck backup agents) will stop your Mac from overheating while the lid is closed.

Alternative: iStat Menus

Use iStat Menus to see exactly which hardware component (Sensors, CPU, or Network) is failing to respond during the wake process.
