This is most likely the reason.

Nor did I say you do, don't get me wrong.

Like I said: the strangest thing I have ever heard of.
Unfortunately, I don't know, how I could help you further.

Would be the best to contact GOG's support team.

I just cannot imagine, how a GOG game could be the cause for this.

Final question: did you download those games all at once, or at different dates and when exactly occured the problem for the very first time?

And did you download some other program(s) from the internet on the same date, or around the same date.

Oh, and what is this icon showing, you've mentioned?

My guess is the power management then.

Go into your Device Manager, click the + beside Network Adapters, then right click and pick Properties for your wireless card. The last tab should say Power Management. Under it uncheck the box beside "Allow the computer to turn off this device to save power"

Can't you take a screen shot and post that?

Im guessing you have a second GOG account then?

Not really the point I guess but meh. Has this been going on since march 11? If so why has it taken 2 and a half years for you to try to fix the issue.

Again not really the point but im curios

I will, but it will take about an hour just to get it to appear.

As per your Avatar /Description, you registered to GOG.com on December 2012...so how could you download a game (Locomotion) on March 2011?

Strange coincidence, that the one game that causes so much trouble was the one, you downloaded, before you even were registered here.

Even stranger, that you waited more than two years before you come to the forums and ask about a solution for your problem.

I'm out of here.

Edit: ah, Reaver894 beat me to it.

No, I do not have a second account, only this one.

As for the issue of not saying anything, I was not sure if this could be fixed, so I kept quiet until now.

Yep, this was my first thought.

I'm sorry about the misleading information about the Mar 23 2011 thing, I was reading that off the game icon.

But here is a picture of the icon.

since you mentioned wireless and laptop over a hour of gameplay, it gotta be the heat or power saving option

How did you buy a game on your account a year and a half before you joined?

I think he just looked up the wrong information, because even in GOGwiki it says the game was released here on August 9th 2011 …

GOG games don't connect out, so they can't really do much todo with the internet. Actually, a lot of them don't even know there is such a thing.

Do you have the GOG downloader running while you play these games? It seems a strange question, but some people like to run a client even though it's not needed.
