OK
Have a router
have 2 computers
plug both systems into the router
I can get online with one at a time
If systems A is online, B can't get online
IF system B is online, then A cant get online
It doesn't matter if one is off or on, (and if it's on it's connected to the net I think)
as long as nothing on the system is actively running online (IE, no downloads, no games etc) the other one
can get online.
WHY?????
