Thanks allot all of yall answered my question perfectly!

Thanks forf the replys but my question was more along the lines of, can they capture crutial info without being connected to the network? If its unsecure or they have a password Thanks all

i have a question that is hard to find on google so i asked it here. This is strictly for wireless security purposes. I have a wifi router and allot of people connect to it. i Know someone can connect to it and do a man in the middle attack. but what if they know the password or its unsecured and someone monitors and captures packets with lets say wireshark,can they get passwords and info? and how? If so can other programs like ssl strip, ettercap etc... be used for this.
