someone's just connected to our password protected wifi, I've already changed the password but should I be concerned?
now's you chance to hack into their system and steal their porn.
>>107697095If you already changed the password you should be fine. Make sure you chose a long password with numbers, symbols, upper and lower case letters so no one can brute force it. If you want extra protection you can also configure the router to work with a whitelist system. But that can end up being kind of annoying because every time you want to connect from a new device you need to add the device mac address in the router settings.
