is it easy to hack into a wi-fi single?

[Just Asking]

I finally moved to town, and after 2 months in a apartment, I have recently moved out of the apartment complex and into a house right across the alley (only place I could afford). Now I can get internet, but am concerned that the people in the apartments might try to hack into my wi-fi since they can not get the internet there.
For some reason, none of the local providers will provide there. Something about a prev tenant doing some illegal activity, so now the entire place is blacklisted.

Would it be possible for them to hack my account and got n without my knowing it?
If so, is there anything I do to prevent it?

You have to set up your wi-fi with a password protected acct. It is fairly easy. When you buy the router it will come with a disc that helps you do it. It will give you a password to give to guests of your home too.

They are easily able to get into your account, i'm doing it right now. the best way for you to fix the problem is to get rid of your wifi or change your password from your phone number, that makes it sooooo easy to get in.
