M1 Mac mini Ventura: No internet after Wi-Fi disconnect

Hello All,

Strange OS problem.

I am running Ventura V13.7.8 on a 2020 M1 Mac mini.

Over the past few days, I have been unable to connect to ANY

sites on the Internet using either Firefox (V149.0.2) or Safari (V18.6). I connect to the Internet via Wi-Fi using a

T-Mobile gateway. This has never

happened previously. I know my Wi-Fi

connection to the Internet is good because if I turn ON Little Snitch, I get messages

to decline or accept connections to various sites. If I reboot the Mac mini, I can once again

make connections. If disconnect from Wi-Fi

I again lose all connections, until I reboot the Mac mini.

I have an M1 MacBook Pro which is able to connect to

any-and-all-sites normally via the same T-Mobile gateway.

Any advice is appreciated.

Tanks in advance,

CEU2

Mac mini, macOS 13.7

Your issue is caused by a conflict in macOS Ventura's Network Extension framework or little snitch system extension failing to reset its packet filter state when a Wi-Fi interface drops and reconnects. Because a reboot temporarily fixes it, the underlying Wi-Fi hardware is fine; rather, the Little Snitch daemon or macOS socket filter is hanging onto a dead routing state.

Try this

Isolate Little Snitch: Fully disable the Little Snitch network filter through its menu bar or app settings to see if disconnecting and reconnecting to Wi-Fi still kills the internet.
Restart the Network Extension: Open Activity Monitor (in Applications > Utilities), select All Processes from the View menu, search for at.obdev.littlesnitch.networkextension, and click the Stop button in the toolbar to force-quit and restart the hanging extension without rebooting your Mac.
