I have a laptop with Vista home premium on it that I am trying to connect to
a network. I can connect and see all the other computers on the network if I
am wired to the network but if I go wireless all I can do is surf the web.
What do I need to do to be able to see the other computers useing the
wireless feature? The other computers are XP and yes I am on the same
workgroup. Everything works fine if i'm wired in but not if i go wireless.
