For more great tips visit: www.JohnzPCHut.com I recently build a new PC using an “ASUS M5A78L-M LX” motherboard. I noticed that about two months later, my Internet connection started mysteriously dropping. Here is how I Fixed the problem. This problem seems to be associated with the on-board Realtek RTL8168 PCI-E Gigabit Ethernet NIC. I have found that by un-checking the “Allow the computer to turn off this device” setting, resolves this problem. Note: I am running Windows 7 Professional 32bit, but I have seen comments on the Internet that it affects other versions of Windows 7 and some distributions of Linux as well.
