Dell Vostro 3460 lost internet connection randomly

Hi,

It's really randomly. When i first start my laptop, it's usually disconnected from wired network. In Device Manager, Ethernet Controller driver is disappear, "scan for hardware changes" and it appear with yellow triangle and error code 10 - this device cannot start. I must restart computer to get it back. Then it work, but after a period of time, may be 2h, 1h or 15m, connection lost again. Ethernet Controller disappear again in Device Manager and cannot take it back without restart. It can may system freeze and have to press power button.

I'm using windows 7 ultimate 64 bits. I tried to reinstall it a few time, install driver in Dell Driver Download webpage with right order in forum guide, update windows but it doesn't work.

I tried restart and boot into ubuntu 13.10 32 bits when it has problem but connection sometimes still lost.

Thank.
