There are other issues with cable BB services, including they tieing a mac address to the given ip address or that particular outlet. Now I ask if you used this card before, do they know this mac address, do you have to go on to their site under your service account of some sort to set your own things including your mac address... things like that. I think it's common to be able to specifiy several on the assumption that some have domestic networks. I have one of the D-link DI604 routers which carries out a lot of this for us and we didn't have connection problems with either of the Linux boxes going through it. GA!
