help help wireless lan prob

Having successfully networked (I think) my main computer to my laptop, I
just cannot get explorer to connect to my web server. I can access my host
computer and visa versa no problem. I get the internet gateway icon in my
network settings. together with the icon in the toolbar saying connected to
my hosts net connection,. iv tried all sorts. I only am using two home
computers. set to ad-hoc.do I need other hardware? or is that I have to
insert an I.up address somewhere.
