|If there is only one network card installed, there should only be one entry called "Local Area Connection" without any number.|
If there is a number behind the one and only Local Area Connection", it indicates, that there is another entry stored in the registry.
This causes windows to get in trouble with it.
The only chance to get rid of it is, to edit the registry.
This should only be done, if you are familar with editing the registry.
If so, you have to search for alle entries in the registry called "Local Area Connection". This can be done with the program Regedit and the search option from its menu.
Than you have to delete the whole registy folder at the left site, where the searched entry is stored into.
Then search the next entry by pressing the F3 key and delete as mentioned above.
When all entries are deleted, restart windows.
The Local Area Connection will be found automatically during restart.
See whether it works.
You should edit the registry only, if you have a backup or image of your windows drive, to have another try, if something goes wrong.
Please send a reply, if you solved the problem !!!
