I'm moving to a cable ISP from fibre optics and am a bit confused as to how I can make the most of it... Basically the property has a single cable coming into the property and has a splitter feeding cables into two rooms. One has a TV decoder, the other has a cable router supplied by the ISP. I'm not sure if I can do anything with that router - I don't have login details and am not sure if I would break something if I tried resetting it. I would like to have a wired network in the room with the TV but don't know if that is achievable. I see that the TV decoder has been assigned an IP address so it has Internet access and I'm wondering what would happen if I added my own cable router... would it get an IP address from the ISP? Is there any way I can connect up the two rooms?
