Windows 7: Unidentified Network; No Network Access - Powerline Adapters

Unidentified Network; No Network Access - Powerline Adapters

Hello 7Forums.

I'll start off with the scenario that brings me here.

Today, I managed to redecorate my bedroom; where my computer sat on top of a shaky, wooden desk. That desk is now gone, caput, and replaced by a much bigger, sturdier and prettier glass replacement.

Before I dissasembled the computer to re-decorate, I was able to browse the internet at ease. There were no problems at all...

However, after the new desk was setup - and all wires replaced in their correct slots, I find that I am unable to connect to the internet, or even the house's network! For the past year, I have been wired to the router using a RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC. It was plugged into an extension cord, in my room, into the Ethernet port in the back of my computer. Downstairs, it's twin was situated no less than 2 feet away from the router - plugged into the first port.

Now, when I boot up the computer, the network notification presents the following message: "Unidentified Network. No network access", and sometimes presents a yellow ! next to it. So, I am reduced to typing on my mother's laptop - which has no problems connecting to the network.

I am able to use the ipconfig /release command, but unable to use the /renew - it hangs in the command prompt, then tells me that the DHCP server cannot be located. The IP, beforehand, was reverted to 169.254.223.117 - before all of this, I was 192.168.0.5

I've been attempting all sorts of fixes, for the past 7 hours. To no avail...any help would be greatly appreciated!

EDIT: I'll also mention that the DNS server and IP settings are set to automatic.

EDIT 2: Windows Network Diagnostics have determined that "Local Area Connection" doesn't have a valid IP configuration.

The router itself would present you with a new Local Area IP, thus the prefix of 192.168.0.*, so I can almost guarantee that it's not your computer acting up. Personally, I'm not too sure on why or how it gave your computer the middle-finger, but it seems to be the culprit..

I'd try resetting your router back to Factory Default settings (Unplug its power source for about 5-10 minutes), plugging everything back in, and seeing how it goes from there.

EDIT::

Also, when you get the chance, I'd check to see if there are any available firmware updates for your router... just saying. Hope all is well mate.

Try applying a static IP address to your PC and see if you can connect then.
see: How to Assign a Static IP Address in XP, Vista, or Windows 7 - How-To Geek

Use an IP addres that is high up like 192.168.0.177 (It will be out of the DHCP Scope so wont be given to another PC).

Follow Agent Zach's instructions. I would upgrade the firmware first and if that fails do a re-setup of the router.
