I just got a "Smart TV" that's smarter than me. In order to set it up for the "Smart" features I need to enter my personal wireless router password. Of course I never wrote it down. Is it hidden in my computer somewhere? I have Windows Vista and I have searched the Control Panel but can't find anything that leads to "router password." Please help, this is driving me nuts!

P.S. My key for the letter P came off. Is it repairable?
