wifi disconnect when locking screen in mountain lion

Hi,

I've been having an issue with Mountain lion, where i disconnects from wifi when i lock the screen on my macbook pro.

I've searched a lot trying to locate the issue, and have found that there was a tic box in Leopard under Advanced in wifi settings (http://www.shepherd.edu/itservices/wireless/macleopardwireless.htm see image 4) where you could enable or disable the feature of disconnecting the wifi when the computer is locked. The feature was called "Disconnect from wireless network when logging out", and i can't locate the same feature in Mountain Lion.

I would greatly appeciate it if anyone had a solution to this.

I am having a similar issue with mountain lion. I know that the machine is not sleeping, just the display but for some reason it seems to disconnect from my network. I'm not sure how long it is but when the machine has been idle for a few moments, Remote.app can not longer see my iTunes library. I have also noticed that I have activated the screen and then emails have been sent, which I thought were sent before.

The machine also refuses to acknowledge Wake on LAN calls and I cannot VNC into the machine from my iPad.

Hopefully there is a preference I can change or that this gets fixed in 10.8.1

I have exactly the same problem after a new installation of Mountain Lion. It's actually pretty annoying if I need to leave my computer to run some long-term codes with internet access. Hope Apple can notice this issue soon and does provide a fix!

I'm also having the same issue. When the lockscreen kicks in after a while my VPN connection disconnects for no reason.

With Lion that was not happening.

Does anyone at apple care to respond? this is an extremelly annoying behaviour and another one of those changes to the default behaviour that does not make sense.

I don't think so, unfortunately 😟

But, what i have noticed, is that it might be based on what type of network i connect to, if it is a 802.1X network, or a WPA2 Enterprise authentication based network. Can anyone one else confirm this?

I thought maybe you were on to something, as my network at work (where the disconnects happen) is 802.1x/WPA2-Enterprise. However, I just tried it at home with my WP2-Personal network and I also saw the network drop after locking my MBP.

Hi I've found a solution to my problem, just posting it on here for anyone else experiencing the same issue.

The problem with OS X is to "lock" your screen you have two options, either let the screen saver time out and lock your screen (which doesn't disconnect WIFI) or clicking on your "user name" on the top right corner and choosing "Login Window" which essentially locks your mac and takes you to a login window, however this approach disconnects the WIFI Connection.

The work around I have found is installing an app called "Lock Me Now" from the app store and once it has been installed launch it and from the preferences "check" "Just Lock" under "Lock Type" which does the same thing as the screen saver timing out. Also for ease of use you can assign a keyboard shortcut to simplify the process of locking your Mac (I chose to use Command + L )

Thanks everyone.

Well I am about to find out if my approach is going to work, but I am sending a ping every 30 seconds hoping it will keep the connection alive... If it does not, I told my iMac I will send it to the junk yard and replace it by a PC. It did not like it so it better obey! ;-)

Open Terminal and issue ping -i 30 some.host.you.own. I can imagine if you send pings to some host they will get mad about it and ban you..

I used the Screen Saver approach and it's working perfect.

I have Alfred with my Command +Spacebar shorcut, and I assigned an easy two letters command for the screen saver. That way WiFi doesn't disconnects.

Hope It helps forward.

cheers!

Update: Well sending a ping -i clearly doesn't prevent the machine from going into sleep and thus removing itself from the wireless.

The solution is pretty simple though: in energy saver, just set that the display has to go to sleep after 1 minute but set that the computer goes to sleep: NEVER. ( Slide slifer totally to the right )

You may allow disk to go to sleep whenever possible. This approach works for the moment. My screen goes out after a minute and keeps out even when I access the server remotely. That way power consumption is acceptable.

Good luck with it.

Apple doesn't routinely monitor the discussions, which is probably why they haven't responded. This is mostly a user forum.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Or you can use your Apple ID to register with this site and go the Apple BugReporter. Supposedly you will get an answer if you submit feedback.
