Do you have local area connections 1 through to 10?
This is very unusual as you should only have 1 or 2 on average.
The local area connection generally is your network card (Please experts, don't flame me I know there is a lot more to it than that)
Has somebody been trying to set other connections up for you?
I would 'hesitantly' advise that you check which is the live one (e.g. the network card) and remove all of the others.
Obviously if they are there for a specific reason I would leave them but I think we need to know more about your setup.
The other obvious question is have you changed/removed/installed anything two weeks ago?
