Wifi card that often disconnected on my MSI laptop

Hello, I have a problem on my laptop (not my connection).

I connect to the Internet via WiFi, and after a certain time (it varies its 10min is a 3h) that I pass it on the Internet is disconnected.

So if someone has a way for my home wireless network please help me.

Thank you

In the material properties, see if the option "allow the computer to turn off the device" is not checked. or change the channel your wireless box.

I find little or material properties that you said? I do not possible whatsoever that I have already seen something checked.

In short could tell me the location
thank you

Right click on My Computer -> Properties -> Device Manager -> NIC -> right click on your WiFi card -> Properties -> Power Management

after the properties of my wireless card I have no power management ...
how can I do?

it does not even with the case stalled. I therefore use the alternative. I did not box but a Netgear router so I do not just change the channel, finally I believe.

If someone has a solution thank you.

Try to change the channel (of course you can do with your netgear). As you open wireless network (your neighbors) with you ?
