Using Windows 7 Home Premium or Windows 10 with an 10/100 Onboard Nvidia Ethernet controller, Cat5 Ethernet cable, and AT&T router/modem combo (on a known good port); randomly, I will lose half of the connectivity to my machine. That is, I can ping out, but not ping in from anywhere. What could be causing this problem? It seems to happen when I'm not using the machine or have let it idle for a long time.
This machine is using a static IP (192.168.1.59), as are all the other machines on this network.
From any other machine:
$ ping 192.168.1.59

^C

Disabling then Re-enabling the Ethernet controller solves the issue, at least temporarily. It happens regardless of activity.

MAJOR UPDATE: DHCP does drop the connection.
EVEN MAJORER UPDATE: It just happened with a PCI ethernet card (non-Nvidia). Is something wrong with my OS, or what?
Ok, new update: Windows 10 started having instability issues (random hard reboots) so I formatted and went back to a clean install of Windows 7 Home Premium. I'm running on the PCI ethernet card (Realtek chipset) and it is still dropping the connection. I'm completely stumped... Any help is appreciated.
