I recently purchased a DIR-850L wireless router.  With a wired connection between my laptop and the new router I have an internet connection.  The laptop shows I'm also wirelessly connected.  Without the wired connection I have no internet access.  With my iPad and iPod the internet connection works fine.  I also have a D-Link camera that works fine on the iPad and iPod.  I am running Windows XP SP-3 with IE 8.  I have tried Google Chrome browser on the laptop with the same result.  Wirelessly I cannot sucessfully ping 4.2.2.2 or the in use IP address of the new router.  When I ping these addresses "wired" they all work.  Help!
