i suspect someone has hacked into my network and i'd like to confirm it by monitoring the mac addresses that access my wifi network. is that possible and how do i do that?
i know i can change the password and they will be denied access until they hack in again. i also know that i can restrict access to just the devices in my home but i'd still like to confirm that unauthorized users are causing me to exceed my monthly usage limit. all of the overage is due to increased upload traffic and neither my son or i use a cloud service, torrents or on-line gaming.
