I'm trying to set up an internal network in my parent's house so that they can stream movies from their iTunes to their Apple TV, without the use of the internet (the signal is really bad in their house). They currently use a 3 Mobile (UK mobile company) 3g dongle which connects to the internet relatively ok, but they have no wifi so I need to set up a local area network. They have a Netgear router (DG834GT) which they have used in the past, so I thought I'd use this to set up the network. Problem is, I can't seem to get it to work. It doesn't find it when I type 192.168.0.1 into safari, so I can't set it up. Any ideas why it won't find it? I'm assuming it's something to do with the 3 dongle and it's own settings? When I check network preferences it shows the USB Modem connected, but the Ethernet says inactive. Can they both be active at the same time? Basically, how do I set this up... I have literally no idea what I'm doing. Many thanks in advance. ps. I'm using an iMac 2011 27" running Lion to set this up.
