Feasibility of second modem setup
I currently have a VM package with Broadband, TV and Line Rental. I'm out of contract and I don't want the TV or Line Rental any more, but am wondering whether it's feasible that I can repurpose the coaxial cable that previously connected to the TV box, to connect to a second modem? I could then use that second modem as a more isolated setup for working from home. Is that possible?
Secondly, in terms of acquiring said second modem, would I need to get one direct from VM or can I buy externally, and if the latter, are there any type/features/specs I need to be aware of from a compatibility perspective? I'm currently on a 500Mbps speed (contemplating upping to 1Gb anyway) and as a point of reference I think my current modem is a Hub 3.0. p.s. I'd probably prefer a combined modem-router for the second connection.
If all that is possible I'll no doubt still need to explore whether I can drop the TV option in my package, but still use the 2 cables - so many things to think about!
All advice greatly appreciated!
