Losing Internet Connection over Sleep?

This is a BIG problem for me, and one for which I hope there is an easy solution...

I was connected to the Internet and stepped away from my computer for about 30-40 minutes, and when I came back both my 1.) Internet Connection, and 2.) WiTopia Connection were down?!

Before leaving, I did Control+Shift+Eject to turn on my Password-Protected Screen-Saver on Mountain Lion.

On my old MacBook with Snow Leopard, I *never* have this issue...

Once I get all of my data copied over to this new MBP, the problem I just described would be an *enormous* issue, because I am a major audiophile who records broadcasts all weekend long.


And if I get up and go have supper, and come back and find that I just missed 40 minutes of Casey Kasem's AT40 - The 80's countdown this weekend, I will absolutely flip!!! :mad:


When I was setting up my MBP this Summer, I had this issue, and I did something which I cannot remember which seemed to have fixed the issue, but apparently didn't.


Not sure if I am being too vague here, or what details you guys need to help, so just let me know?! :confused:


Bottom line is... I do NOT believe that the Library's Internet and WiTopia just happened to go down while I was away.

It seems like my MBP was off long enough that something happened and it *dropped* the Internet Connection and my WiTopia Connection...

Help!!

It is almost the weekend and my radio shows are counting on you!! ;)

Sincerely,


Debbie

You could use an app like Caffeine to keep your Mac from sleeping.
Before I do that, I need to understand what is happening... :(

Why is my MBP dropping my Internet Connection?

When I do Control+Shift+Eject it doesn't affect my Internet Connection.

Doesn't that put my MBP to sleep?

Sincerely,


Debbie

What is causing the issue I described in my OP?
There's a possibility that while you are away, your Mac goes into sleep mode, which could account for the loss of Internet connection. Using an app like Caffeine, as I recommended, will prevent that from happening.

What if I just adjusted my Power Settings to Computer = "Never Sleep"?

Would that fix the issue?

And could it cause any damage to my MBP?

No it can't damage your MBP to set it to not sleep. However, the Caffeine app is much more convenient, as you can simply click the icon on your menu bar to activate or deactivate it, overriding the power settings when you need to.

I have "Wake for Network" checked under Power Settings, so why isn't that working?


The problem I am encountering seems to have frustrated many a Mac user...

Is this an unfixed bug in Mountain Lion?

I've read several accounts of problems with the "wake for network" settings. The app I recommended will enable you to prevent your Mac from sleeping when you want to. It's a free, simple and reliable solution.

So you are saying that it is *just* when my *computer* goes to "Sleep" that my Internet Connection is being dropped, right?

In other words, if I set Computer Sleep = "Never" but Display Sleep = "5 Minutes", then when I don't lock things and my Screen-Saver kicks in after 5 minutes, what would happen??

(I understand you are suggesting "Caffeine", but just trying to understand how my MBP works first.)

That's the likely scenario, yes.

That should work. Test it and see. If it doesn't, you can try the app.

Yes, I am going to play around with things - when I can find time to stop using my new MBP!! :)


So, are there any down sides to Caffeine?

Is it Mac tested and safe?

Yes, it's quite safe. Like many others, I've used it for years with no problems at all. It's been recommended countless times in this forum and elsewhere. I would never recommend an app that wasn't safe.

So the advantage is that Caffeine offers "one click" versus having to dig up System Preferences?

And dumb question, but do you use Caffeine for what we are talking about, or some other reason?

Yes, it offers one-click convenience without having to open System Preferences to change settings. I leave my sleep settings adjusted to maximize battery life, but when I know I'm going to be doing intensive work, I click Caffeine to make sure my MBP or screen doesn't sleep when I step away from the computer.
