Using BT in most of the house and it works fine, but there is a small network (no connection) connected that we want to connect to our Virgin Broadband modem. It seems to work fine on the Mac that they installed it with, but I can't seem to address the modem directly through its IP address nor get DHCP addresses that work off it for other devices. Curiously, things like the AppleTV seem to believe that it has been assigned an address, but the address is both completely different to that on the connected iMac, and doesn't work (listing no DNS or router on the ATV network page). Is there any way to address and configure these modems using a browser? It is connected via coax to the outside word. I can't find a model designation but it does say "Tradename: AMBIT" on the bottom. HELP! I'd like to get it handing out valid addresses or find a way to make it accept manually configured devices. On a related note, the IP address of the router is, for example, 77.149.22.001, on a manually configured ATV, would that be 077.149.022.00x? Also, allowing sharing over the Mac's connection doesn't seem to work either, though that may be down to not having wireless on the iMac, and connecting via Internet which is also the only practical port to switch it out on. It is connected through a dumb switch, but it didn't seem to work through a router with NAT to the modem either. HELP!
