NTL Broadband On The AmigaOne From A PC

[Herewegoagain]

The router connects to your broadband modem with an RJ45 ethernet cable via the Wan port on the router to the ethernet port on the modem.  Most routers will have 4 ethernet ports for plugging in computers to the network.   If your modem is USB only, then you will not be able to use it with a router (none that I know of).

In the case of USB only, setup the USB modem on the PC with drivers and configure your internet.  You will need to have an ethernet card in both the PC and AmigaOne, and connect them with a crossover cable.   Setup Internet Connection Sharing from the PC and select the USB modem as the device which you access the internet with, and the ethernet is for accessing your lan.   On the AmigaOne, you should just setup the network stack to obtain IP address auto from DHCP server.  This should work ok, but requires that the PC stay on to access the net from A1.  Hope that helps and makes sense.

There is no cable modem
It comes through the NTL STB

Well, being in the US, I'm not familiar with their service.  But I took a look at the NTL website and requirements.  It looks like they offer 2 options for connecting broadband:  

1)  Through a cable modem, or
2)  Through your STB with built in cable modem

Taken from their "what you need page".

So you do have a cable modem, its just integrated into the STB.  The big question is if it has an ethernet port or USB only?  According to this page, if you have an STB you should have recieved the following items:

An Ethernet cable
Ethernet-to-USB adapter
Cross-over (x-over) adapter

Those items will allow you to do the things discussed above.

This seems to be a fairly good source of info too:

I use a Draytek Vigor2200USB router that is connected to a USB ADSL modem. They now have a new version with the modem built in.

That's cool they now support USB modems, but it seems these are for ADSL only, and just support about 7 different modems specifically.  I don't think that would work with the broadband service he is using as it comes in via STB and not ADSL.

To quote from the Draytek website :

>>>>> Cable - Cable Modem Interface. The product has an RJ45 10BaseT Etherner socket which plugs into your cable modem or set-top box's Ethernet interface, using the RJ45 CAT5 cable (supplied). This is ideal for UK cable services from Telewest Blueyonder and NTL. The interface can also be used to route to any other type of Ethernet connected network, or another router, including another ADSL router such as a non-NATted ADSL router <<<<

Um.....yeah, I know that the other versions support the ethernet port and cable modems, but you were talking about the Vigor2200USB version, which is why I commented on that one.  A bit of miscommunication I think.
