Unidentified network no internet access

I've been wrestling with this issue since yesterday. When I plug an ethernet cable into my laptop I get a message on the networking icon in the system tray stating "Unidentified Network - No Internet Access". I can however still access the shared drives on my LAN. I can even Remote Desktop to my other PCs.

My laptop is a Toshiba Satellite L305-S5933 running Windows 7 Ultimate 64-bit, the NIC is a Realtek PCIe FE Family Adapter. This is a fresh install as of yesterday (21May2013). There is currently no AntiVirus software, or AntiSpyware software installed and the Firewall is the basic Windows Firewall.

My wireless connection works fine, and I've able to connect without issue.

Here are the results of an 'ipconfig /all'

THIS is the icon I'm seeing in the system tray

THIS is my Network and Sharing status

THIS is my Local Area Connection folder

THIS is the particular Local Area Connection

and THIS is the Windows Diagnostic results

Now it says that "the default gateway is not available", however I have two other Windows 7 PCs (one on wired, one on wireless) and neither of them have any issues connecting what so ever, and previously I'd never had any issues with the laptop as well.

Here are the troubleshooting steps I have tried thus far.

1) Power cycle Cable MODEM, Router and Laptop - let them sit for 10 minutes in a powered off state before powering them back on
2) Switched ethernet cables
3) Switched ports on router
4) Disabled re-enabled Local Area Connection
5) Un-installed and Re-installed NIC driver
6) Updated NIC driver to latest available from manufacturer
7) Tried manually assigning IP address and Default Gateway
8) Setting DHCP broadcast to 0
9) Deleting 0.0.0.0 route
10) Altering Network List Manager Policies in the Local Security Policy so that Unidentified Networks would be Private

I'm sure that there are other steps I've tried too that I simply can't recall at the moment. Needless to say I'm currently stumped and looking for assistance in resolving this issue.
