I'm using Windows7 with SP1. The CPU is an i5 3450.
When the problem started my wife decided to have all of our computers have user login and passwords. Also I believe she tried setting the wireless access to be on a schedule by setting up the router (I showed her how to connect to the router page so she could turn off wireless).
All computers and devices lost connection to the internet and router/modem. I did a full modem reset and was able to get back internet access to all computers but mine.
As the title says I can ping anything, but FF and IE both can not bring up anything including the modem/router using IPs.
