Troubleshooting my 6T04 Adaptor

I have a Satellite A205-55804 and theres something wrong with 6T04 Network adapter. It was working just fine this morning but now its not. Okay so when i log on to the internet you know the little icon in the system tray thats has 2 computers and has a red X in front of them when you're not connected to the internet, well mine remains like that when connect to the internet(i have a dial-up connection). Now i can log on to the interent and browse and what-not but my icon remains the same and doesn't show the blue icon it usually does when i connect to the interenet. Now I know its up to date cause I already ran a search for updates on it, and I ran a network diagnostics and it says there nothing wrong with my network. Also when i put my mouse on the icon this is what it says "Connection Status Unkown" then under it it says "The dependency service or group failed to start". So I have went to my control panel and went to my device manager and there i saw under my network adapters drop down a whole line of 6T04 adapters with the error icon in front of it you know the yellow caution symbol with the exclamation point and when i double click on it to check the device status this is what it says:
"This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"

and under that :

"Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available."

Okay thats it
