Okay not sure how many of you use Steam but I'm sure there's some if not many.

Anyways I've recently ran into two problems of which one is only greatly annoying. I was wondering if by chance any of you had come across these problems and even more importantly had answers to them. I tried finding help for the issue via Google searches with what i'm running into but didn't find any answers or anywhere with someone having the same problem.

But here they are:

1) This is the major one. I got Bioshock during the Holiday sales on Steam. Just now getting around to playing it and it plays fine BUT when i exit the game I find my internet connection has either gone out or says 'limited access'
Now normally I'd think nothing of this but there's really no reason I should be getting the 'limited access' as that rarely ever happens until now (due to this problem) and the connection being completely out I can tell is BS because others in the house are using netflix which is off the same internet connection so obvious the connection isn't out.
So far Bioshock is the only game via Steam that does this to me.

2)This one is really minor but, for audio I have USB powered larger speakers that also plug into the audio jacks I typically use them because while my laptop doesnt have bad sound, these provide better sound and they get louder overall. However, for some reason whenever I go to play any of the new C&C games through steam those speakers stop working and i'm assuming the audio jacks themselves do too as my computer reverts to using its built in speakers which it shouldn't do if something such as headphones or these speakers are plugged into the audiojacks.

This isn't a big deal because I simply unplug and plug the input back in for the USB powered speakers and then sometimes i have to tab out and hit the speaker icon on the taskbar.
Also I have not tried to find this issue on Google anywhere because it's really not that big of a deal but i figured since i was going to be posting about the 1st one I might as well include this one too as someone here might have an answer to it.

Anyways, thanks to anyone who helps or tries to help.
