1) You can jump through a buncha hoops trying to learn how to recover your key.
2) You can reset it and have to start over, and yes, if your network is setup a certain way it will effect it, you will have to go through and manually set it up again, no problem if you know all your networking credentials, pain in rear if you don't.
