Windows 7 keep loosing Internet connection when streaming video

   Every time I stream a movie to my laptop, or PS3 my internet crashe on the Windows 7 Machine where I'm getting the videos from.
I have a Windows xp laptop and a MacBook that keep working on the Internet so the problem is not on the router.

Before the Machine was working fine when using Windows XP. I did a clean install of Windows 7 32bit and now this is happening after a few minutes streaming video.

To restore the Internet connection I just disable and re-enable the network adapter and start working again for a few minutes.

If I don't stream videos Internet doesn't drop at all.

I have unchecked the option "Allow the computer to turn off this device to save power".

Some more info:
Network Adapter is: Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller (Before with Windows XP it said in device manager : Attansic L1 Gigabit Ethernet 10/100/1000Base-T Controller) but I assume is the same.

Any ideas on what to do?
I've google it and it seems that I'm not the only one with this problem but I haven't found any solution. I hope that in Expert Exchange at last I can find an expert :)

Thanks

Where are the videos located? On the Internet or on the Windows 7 computer?  

And is the Internet connection crashing or the connection to that computer?  Internet does not equal network, this is why I am asking.

I'm just trying to clarify to get a better idea of what is happening.

4ToNight: Did you updated your network drives directly from Device Manager or you downoaded them manually? When I do drivers update Windows tell me that it has the last version already.

rfportilla: Videos are located on the Windows 7 Machine and I have some also in an external driver connected to that machine. btw, it doesn't happen only when streaming. I was actually coping the video directly to my laptop via wireless and after 250MB or something the connection to that Windows 7 computer got lost. I check and the same as before happen. No Internet connection on that machine.

What is crashing is the connection to that computer. All other computers can connect to the network fine. Macs, WIndows XP, and even Linux are connecting ok, only the machine using Windows 7 have problems dropping the connection.

I'm going to try manually downloading the drivers for the ethernet card and report back if it works.

you are not the only one having trouble with this nic.

I saw some post they tried drivers from this website and it solved their problem.

Or some other people just bought a cheap 100/1000 nic.

It stops connecting altogether. I have to Disable and re-enable the Local Area Connection and in 5sec is working again. If I do a repair (Diagnostic) it doesn't work.

Are there any wireless connections between the 2 computers?
I don't get the question.

I'm going to try installing another Nic..

There are 2 solutions:
1 - Buy a new NIC
2 - Go into Atheros NIC adapter properties. click 'configure' tab & disable all the task off-load settings.

The second solution fixed my problem. No more disconnection. The only drawback is that it seem that with this option turned off my NIC cant handle multipe internet request anymore for some reason.
