Intermittent invalid IP configuration
Hello,
I am having intermittent connection issues to the Internet when connecting via my ethernet adapter. My modem connects to my router (D-Link DIR-825) which connects to a Sling Media Powerline kit (see here) via my electrical system which then connects to my ethernet adapter (nVidia nForce network adapter).
I can connect to my router wirelessly perfectly fine. However, when using my ethernet adapter, it will intermittently stop working every ~10-20 minutes or so for a period of ~10-20 minutes. If I run the Windows 7 network troubleshooter it informs that my connection does not have a valid IP configuration and that the default gateway is not available, but it cannot fix either of these problems. Eventually it seems to sort itself out, but it is only temporary. Previously, this network configuration had been working perfectly fine for nearly a year.
When I run ipconfig /all in the command prompt, I get the following relevant portions when it is not working:
When it is working, I get the following:Code:Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved.

It is my understanding that Windows assigns an IP address in the range 168.254.xxx.xx when it cannot get an IP address from DHCP, which in this case would be in the range 192.168.0.xxx. However, I do not know why it cannot get an IP assigned. I have tried setting a static IP outside of the DHCP pool, I have tried releasing and renewing ipconfig, I have tried restart netsh via the command line, all to no avail.
Thanks in advance!
