Dell :: Studio 1555 Will Not Pass Authentication With D-Link DSL 2750B Router

I am probably missing something so obvious, but I have been working on it for three days.  I received a new modem DSL 2750B and have it LAN wired to my Dell Studio 1555.  I asked my techy step son to hook it up to wireless while I was away.  He could not do it and worked with Verizon to create a home network changing the SSID and WPA Key.  They spent about a hour together on line and could not get the wireless to work and Verizon said its a problem with the Studio 1555.

So, I have been working on it since and can not fix it.  The Studio is out of warranty and I have Windows 7 Home Edition.  I spent a day and a half to finally get the Function F2 button to work and turn on wireless.  This was only possible after downloading the Dell Quick Set and now the Radio On button shows in my Windows Mobility display.  I checked my BIOS and Radio, WiFI, and WAN are all enabled.

When I boot up I can see the wireless network showing as available and at excellent strength.  I click it to connect and it fails authentication.  I ping the router at 192.168.1.1 and it shows both wired LAN and wireless LAN connected.  So, I go to Wireless and go through the push button method of signing on to the router, pressing the WPS button on the router.  It "spins" for 120 seconds and says fails enrollment. 

I am thinking that I should have my laptop and router all reset and eliminate the network Verizon and my step son set up.  This would give me a clean start and I can use the SSID and WPA key that came with the router..but, I'm not sure that is it or am I missing something else.
