Windows 7 - Windows 7 to AirPort Extreme via Ethernet Cable Issues

I just built a new computer and have Windows 7 Home Premium 64bit installed on it and it is connected via ethernet cable to AirPort Extreme but my computer says there are no network connections, does anyone know how to fix this?

If it matters this is my build:

Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor BX80601950

CORSAIR CMPSU-850TX 850W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready Active PFC Power Supply

GIGABYTE GV-N570D5-13I-B GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

Western Digital Caviar Blue WD10EALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

GIGABYTE GA-X58A-UD3R LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX6GX3M3A1600C9

Can you log into your router by typing its IP address into IE?

No, it cannot display the page. It seems to be the whole back of the motherboard. The USB Ports don't work when I plug in the mouse or keyboard, nor do the actual mouse or keyboard slots. I have power on them, they light up, and the mouse and keyboard light up, and the spot where the cable is plugged in lights up, but I can't move the mouse or type on the keyboard. So, right now I have them plugged into the front of the PC and they are working fine.

It worked when I first powered up the PC, but I had an issue originally with Windows reading the HDD, so I had to open the case and mess around with the SATA cables and when I rebooted it up the mouse and keyboard stopped working on the back panel. But I don't understand why I have power on them but they're just not working.

Right now, I am leaving the computer unplugged for a little bit then going to plug it back in and see what happens. I'd assume a cable or something must have come unplugged on the MoBo, but rationally I don't think that's possible if I have power on the back panel.

If you enter your BIOS, is "Legacy USB" or something similar enabled? If not, enable that, plug your keyboard and mouse into the back USB ports and see if they work.

If you were messing with stuff inside the computer there is a good chance the board saw a bit of excess voltage in the wrong places, they can be very sensitive to that sort of thing. Clearing the cmos would be my first choice to fix this sort of problem.

The process is a bit different depending on who made your board. If you built this machine yourself you should have no problem figuring out how to clear the cmos.

Reset the CMOS and enabled Legacy USB (well, something similar -- forget the exact name), and the USB ports in the back are now working. The network, however, still does not. I tried trouble shooting and it reads:

Got it. Didn't see the Ethernet update. Wow, I am an idiot. Thanks everyone.

So its all working OK now?

Yes, thanks.

Glad to hear you got everything working again mewithoutYou, Happy newyear.
