@ Reba-- I need to be able to see the questions, so pardon my not quoting you.
How I know is because Google would have alerted me to an attempted login from my account, and my other e-mail accounts would have likely done the same thing. I know for a fact that Google did this before, so that's how I know.
As for guessing the password-- there's only one possible clue-- my former password had a clue in my Albums, so I'm guessing that the person who may have guessed it (If he/she did) would've known I was there, and might've used that to guess the password. and yes, I AM using a strong password-- maybe too strong. I have quite a long one, and it's a bit complicated, but if done correctly, I can get in.
For using the default admin password, I didn't even KNOW it was there-- until I did some digging, and contacted Clear, who told me. I can try, but doubtful it would work. I'll make an inquiry after I'm done with other things. Good thing they're 24 hours.
I am currently using a Private Network-- it's secured, so I am okay. As for who owns it, I can't say the name, because their rules prohibit it. Let's just say it's a program for the mentally ill, and they aim to help make our lives better than ever. That's all I can say. Same for the VP-- it's not under my name-- if it were, I would've done things differently.
No, the AT&T WiFi's are not public-- they are password protected, and only a few people who know the passwords to them have access. What I am trying to figure out is how the person got access to both. I'm also confused if it's in inside job or outside job. That part is the hardest to pinpoint. If I hadn't successfully traced all three of the IP addresses to the WiFi's, I wouldn't know what to do, but now that I have, I have a little bit of a better idea of what to do this weekend and next week.
