I recently moved into a new place (rental) and I'm wondering if the following is possible. There's a single coaxial cable that powers the internet connection. It is currently hooked up to a modem provided by the ISP, which we connect to wirelessly. There are other tenants in building that use this same connection.
I have a Unifi Dream Machine AP that I'd like to use. I've plugged this directly into the modem of the ISP and it works fine right now. But, I've been running into problems with port forwarding, etc as the modem is not in bridge mode since there are other users of it. I'm also concerned about performance, and generally would like to skip the existing modem middleman.
I'm wondering if it's possible to use a splitter on the existing Coaxial cable, having one end go to the modem (as is done currently), and have the other go to my access point to run a different wireless network. The only thing there is that I would need to convert the Coaxial to Ethernet, which seems possible to do through a MOCA adapter. Is there any issues with two different networks using one Coaxial cable (performance, or otherwise)?
Thank you very much!
