New Dell Laptop can't connect to home network

[okayplayer]

Hi, sorry for posting this here, but I figure you guys would have similar experiences and are the best responders. I just got my new Inspiron 6000 and I live in a house with a Netgear wireless router which all the computers are connected to. I am able to connect to the internet, but not to my network (i.e., connect to the other computers). I ran the Network wizard and put in the "name" of our network, and still nothing. When I click View Work group computers, it is busy for ~30-40sec and then gives me an error message saying it could not connect to the network yada yada yada ... contact the administrator...

Could anyone help me on this?
