My retina macbook pro's network locations keep either disappearing entirely or changing to "unknown". I wouldn't really mind but it stops my wifi from auto reconnecting when I open my laptop up. It doesn't forget the address (password) but it does forget to automatically connect to any known networks. I haven't really found anyone with a similar problem by searching but I've done the usual troubleshooting (reset pram and SMC). Another symptom is that my laptop's name keeps deleting itself also (_____'s macbook pro - the "computer name" that you can set in the sharing menu in system preferences). Any help would be appreciated.
