OK.... On the IPv4 properties page switch everything back to the way it was.
One more thing we can try is turn off your router and leave it off. Go into "Network and sharing center". On the left side of the page click on "manage wireless networks".
Right click any network listed and then delete. Boot down your PC.
Hard reset your router again back to factory defaults. When your router is back up and running boot up the PC and set up a new wireless network.
