Windows 7: Intermittent invalid IP configuration

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:

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!

It looks like you want to use your lan connection so I would disable your wifi and if that fixes your problem search this site for how to change the metric of your lan just in case you want to enable your wifi for some reason set your lan to metric 1 and your wifi to something higher like 10

If the network was working properly then the wired connection would override or disconnect the wireless connection the second it was plugged in.

If the Sling Media power line kit has any type of DHCP server that you can disable on the UI then that may clear up the problem. Although since it was working before you might try resetting the D-Link DIR-825.

To change the metric, I went into the properties for the adapter, then IP v4 > "Properties" > "Advanced" > uncheck Automatic metric > fill in "1" for "Interface metric". I did the same thing for my WiFi adapter but changed the metric to 10. I still get the same problem, however. It should be noted that even when my WiFi adapter is disabled and I am only connected via my LAN adapter, I get this issue.

Just to doublecheck, I switched out my CAT5 cable for a different cable, tried connecting via my second ethernet port (my motherboard has two identical ethernet ports), and updated by nForce networking drivers. I also tried setting a static IP address again. None of this helped at all.

As far as I can tell the Sling Media power line device has no UI or accessible settings. Resetting my router did not help.

Thanks for the replies.
