1. Goto Start, Run, type: NETSH DIAG GUI - press 'OK'. A Command Prompt window will open temporarily; don't touch it, it will disappear in a moment.
2. A Microsoft Help and Support window will then open; select the option 'Scan your system'.
3. Wait for the scan to finish and then scroll down to the heading 'Modems and Network Adapters'. Look at 'Network Adapters' (don't expand it yet). Beside your connection information, you should see a green 'PASSED'; if you do not (if you see a red 'FAILED') then expand 'Network Adapters', scroll down the list until you see the heading with the 'FAILED', expand that option and copy and paste the results here.
In the NETSH DIAG GUI, you should be looking for any red 'FAILED', however the key one is Network Adapters for you. If you see any other red FAILED, expand the component and copy the results.
