Hope you can help.
In our household we have 3 computers, 2 desktop (Computers A and B) and 1 laptop (Computer C), all of which are running windows XP. we are trying to connect all 3 to a network plus have internet acces through a cable (ADSL broadband) modem. at first computer A had access to the net and computer B could access the net through this and could see computer A's files, etc. now we have added computer c and none of the computers can see each other and only computer A has internet access again.
All computers and internet connection are plugged into a 5 port network hub.
I have run network setup wizard on all 3 compters, but no joy.
None of them can ping any of the others and im completely baffled!! At one point computer A could see computer B for accessing files however could not see each other when trying to play network games.!??!
