Hi Lefkows,

I understand that when your Mac sits idle for too long, the Wi-Fi disconnects. I know it's important to have a reliable internet connection, so I'm happy to provide some help for this issue.

I recommend using the steps in the article below to create a new network location, then test this issue again:

Thanks for using the Apple Support Communities. Cheers!

If you have done the above, and still have this issue, do following:

hold the Alt/Option key while clicking the WiFi icon in the menu bar: you get a very complete list:

with Shift+CMD+4 keys you can make a sceenshot of that list. Post it here.

Also try turning off Bluetooth.


If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.
