I bought a 2nd apartment in the same building. The internet for my 1st apartment is provided via (coax) cable, cable modem and a router.
The ISP (which is also cable TV provider) installed a box in the basement, attaching every apartment in the building with a coax cable. I don't know the details of what the ISP box contains, but my guess is that it contains splitters and amplifiers.
Note: I don't use cable TV in any of the apartments.
Sine I don't want to pay the ISP twice, I would like to use MoCA to get the internet in the 2nd apartment from my 1st apartment. I attached a rough plan of the setup I would have in mind.
I have some questions regarding the two setups I could think of:
- In apartment 1 add a MoCA splitter before the cable modem, attach a MoCA adapter in both apartments and hope this works, even if the ISP box is between the two apartments.
- Would this setup even work? (since I have no idea what the ISP box contains ... maybe someone has a similar setup and could share his/her experience)
- As far as I understood, I shouldn't add a PoE filter between the ISP box and the splitter before the modem, since this would "disconnect" the two apartments. Is that assumption correct? What are the consequences of not using a PoE? Could someone in the building interfere with my setup? Could anyone in the building use my internal LAN by attaching another MoCA adapter?
- Same as setup 1. Additionally - in the basement - add a PoE+splitter between the ISP box and apartment 1. Then separate apartment 2 from the ISP box, connecting it to the newly added splitter in the basement.
I would be glad for any advice you could help me out.
Thanks
