Identifying Connection

What exactly isn't working?

I now see the default gateway again and your IPv4 address is now showing up. It also doesn't say Media Unoperational any more, so those problems are gone because of resetting the router just like I mentioned in my first post. I hope you have your router set up for auto DHCP assignments?

You might also try flushing the DNS by typing
ipconfig /release
ipconfig /renew
ipconfig /flushdns
into the command prompt one at a time then hit enter.

Also try returning your HDD to the normal state, plugged back in like it was before into the same SATA port and remove the new one that you added for now since changing them seemed to cause this problem to begin with.

Also if you are using anti virus software or a third party firewall uninstall it for now.

Your DNS connection suffix should be showing your ISP name like mine shows san.rr.com, which tends to go back to the modem needing a reset like I mentioned earlier. Have you performed a complete reset starting from the Modem yet?

If you are concerend about where it says Media Disconnected? If so that is perfectly normal as I already mentioned before, that is what it always says there, notice my ipconfig says the same thing as yours and everything is working for me.

If you are running Apple programs with Bonjour try this. Start > Control Panel ( Large Icons ) > Windows Firewall > Allow a program or feature > Allow another program > Right click on Bonjour Sevices and delete .
