Hi,

I have a couple of questions about Virgin Media cable broadband (ex-NTL area).

Specifically, I understand they now only supply new users with standalone ethernet cable modems (no problem here as never intended to use USB) (also would be broadband only / without a STB anyhow).

However, as well as wondering about the MAC binding issue (I understand this is less of an or no issue now - power cycle modem, etc.), I was hoping someone would clarify if the following scenario would work. In the absence of sufficient length of cat5 could I insert a hub or switch in the middle of a run of cable from the cable modem to the pc? I.e. cable modem --> hub or switch --> the one pc that will use the cable modem?

My instinct / thought is that the answer is probably not - perhaps a bridge would be needed. But any input appreciated. (I wonder a little bit because if the cable modem is not routing how can it necessarily determine the remote machine as being further on down the road through a hub or switch rather than being directly connected into a computers ethernet port - but I guess maybe it comes down to the "routing" [as in switch routing tables / maps {not NAT type router stuff}] / "relaying" function of the hub / switch).

Best wishes,

A Cableforum Fan

P.s. I understand this is pretty much the best Virgin Media / cable / cable broadband site / forum / resource. Is that right, are their others worth knowing about? Thanks.
