I have a couple of iMacs, one of which I use as an access port.
Works fine for the other Mac, iPod Touch and iPhone, but I cant get a laptop with Windows 7 running to connect.
The Mac is wired to a wireless router, when the laptop is in range of this router it connects fine, but its out of range in parts of the house hence the need to use the Mac as access.
Not a computer expert so be gentle please.
