Unable to connect to modem/internet via lan but wireless works fine
My desktop (windows 7 ultimate 64bit) has been able to connect fine to the internet until I got home from work this morning. My laptop is connecting to the same modem fine through wireless (along with my wii). The modem I am using is Motorola SB 901. When I rightclick my connection on my desktop and hit troubleshoot problems, I get 'local area connection 2 doesn't have a valid ip configuration'. Same thing happens when I switch the ethernet cord to local area connection 1. When I go to control panel, network and internet, network and sharing, the connection map at the top stops between my pc and the network (which is now labeled as 'unidentified network').
Here is a list of what I have done so far to try and resolve the issue:
1. Replaced the ethernet cord with one I know is working
2. Full scanned my pc for viruses
3. Disabled all firewalls and virus protection programs
4. Restored my pc to a previous save state
5. Reset winsock with cmd via these prompts: netsh winsock reset catalog and netsh int ip reset reset.log hit
6. This attempt is unfinished as I am getting stuck. I am attempting to setup a static ip to attempt to resolve the issue, but when I open cmd and type ipconfig/all, the default gateway under my local area connection is completely blank.
Here is what comes up with ipconfig/all:

7. Powercycled modem pc and every device that connects to my modem via wireless.
Any help towards this issue would be great. Can't seem to find anything useful googling my issues!
Extra info that may be helpful. Anti virus is Microsoft Security Essentials. Going into device manager and checking under network adapters, there are no issues showing for my network adapters.
