Since Monday night March 26th both my Nortons AND my Cisco Firewall are getting intrusion attempts both on my home wifi router AND also on the generic 'xfinity wifi' which I've tried to connect with once my firewall shut down my home network. None of the logs ive looked at include any ip or website info. Just "multiple external network manipulation attempts". According to Nortons this appears to be originating at my ISP's node and not just my house. How can I deal with this besides disabling my wifi router? Every fix i try seems to be countered by the potential intruder. The last two intrusion attempts came over my LAN hook-up, since I'm not using wifi at the moment, given the security warnings.
