I'm connected to the Internet via router (wired) and Ubuntu disconnects me from it. I have to manually disconnect from my network (via panel in top-right corner) and connect again. I don't know why. Can someone help me? I will give any information that will be needed.

P.S. On Windows 7 everything is OK, so it isn't the fault of the network card.

You haven't given enough details to accurately diagnose ..

(the obvious) Check your settings.

(Network Icon) >> Edit Connections

It should look like:
