Is it legal to connect to an unsecured network?

Provided they don't have a firewall to block you out of their network, yes. Anytime someone has a wireless network in their house, it extends farther than the house usually. You could theoretically drive coast to coast, and hardly ever loose a wireless network to tap into.

Also, If they have a security-enabled network, you will need to type in a passWord to get into the internet. Most people have a security-enabled network, because who wants someone else gettting on internet they are paying for? I have a security-enabled network. It works great! And you can see who is on your wirless router and you can kick them off any time!! That is what I like about secuity-enabled networks! Well, bottom line, you can get on someone else's internet, but you will be promted to type in a passWord, unless they have an unsecured network!
