Wireshark and a wifi monitor have shown that there is a Smart ARP and Smart DNS attacks running on the shared wifi in the house that I live. I have a MAC address associated with this, but have no way of knowing if it's someone in the house or outside. No matter what firewall I use, eventually they get through and change permissions, set up a super user account, leave a keylogger, and change the registry. My separate wifi hotspot has also been cracked.
