Wi-Fi repeatedly resets and drops connection

Wi-Fi module resets and known networks disappear temporarily on macOS Tahoe 26.1

Since updating to macOS 15 / 26.1 (Tahoe), my Mac repeatedly resets the Wi-Fi subsystem.

Every few minutes, in System Settings → Wi-Fi, all known networks disappear for about 5–10 seconds and then reappear.

During this period, the Wi-Fi connection drops, reconnects automatically, and browsers often report ERR_NETWORK_CHANGED.

This happens:

• even with VPN completely disabled
• with “Private Wi-Fi Address” turned off
• after deleting all network configuration .plist files
• after resetting Wi-Fi settings and removing all preferred networks

From what I can see, it looks like the Wi-Fi stack (possibly WifiDriverKit or WirelessRadioManagerd) is restarting itself in macOS Tahoe 26.1.

Expected behavior:

Wi-Fi should stay connected and should not lose its network list or reinitialize during normal use.

What I’m looking for:

• Is there a way to stop macOS from constantly scanning for new networks and force it to stay connected to the selected network?
• Any deeper reset steps or hidden configuration options that could fix this?
• Is this a known issue in macOS 26.1?

Any advice would be greatly appreciated. Thank you.
