I am still looking for a solution.

I have the same problem and  found that I could Enable and Disable using the following steps:

1.         Start

2.         Right click My Computer

3.         Select “Properties”

4.         Select “Hardware”

5.         Select “Device Manager”

6.         Find “Network adaptors”

7.         Click the “+” sign to open the folder

8.         Right click your adaptor and select either “Enable” or “Disable”
