I've just bought a new MacBook Pro. When I close the lid or when screen becomes inactive. The wifi connection closes itself.
I tried to search on internet but It shows screenshots of some other Mac OS I think.
So my question is specifically for Sonoma OS. I don't see any option in setting to keep wifi awake while lid is off.
Can someone please help?
MacBook Pro 14″, macOS 14.2
When you use a computer in a busy environment, you get your local IP address via DHCP. This is referred as a 'lease' on the use of that IP address. You can only use and hold the lease for its lease duration, and never beyond the lease period, or your traffic may collide with a different computer's data.
So when you Mac goes to sleep, it does not know whether it will still be sleeping when the DHCP lease on its local IP address expires. To avoid issues, it releases its IP address.
it is possible, with certain settings, that when your display goes dark, you Mac also sleeps.
System preferences > Battery > Power adapter...
Check :
[√] Prevent computer sleep when the display is OFF
it will warn you this setting uses more power.

These settings seem to vary wildly between different versions of MacOS:

It's not just when I close the lid.
When the screen is inactive and it locks itself then also the wifi connection is lost.
This should not ideally happen right?
When at work I switch between my work laptop and this laptop, and in between I have to switch the wifi again and again.
I hope you understand the issue.
when you close the lid, your Mac goes to sleep.
why do you need wifi to continue to be active when the computer is asleep?
do you have a sleep proxy device on your network?
