Splitting one cable connection between 2 modems

[Enemy_uav63]

Would be great to know if i can split one cable with one ip address between the following devices

Netgear CM600 modem with a router or network switch connected

Netgear C3700 Gateway

I cannot use ethernet to connect the two or else i would

either i need to know if you can split one cable connection between 2 routers,

or if i can use an older belkin router with DD-WRT to wirelessly repeat the signal to my room

Any help would be appreciated because we have weak signal in the bedrooms if the router is in the living room and we have a weak signal in the living room and kitchen if we put it in the only bedroom with a drop

So you need a wireless AP in you room.

 

No you cannot. Not without paying for a second Public IP from your ISP. Some ISPs won't even let you pay for a setup like this if you wanted it.

 

Why can't you run Ethernet?

I am unsure as to what you are attempting to accomplish. Why is it that you have 2 modems in the first place? A modem simply interfaces with your ISP in order to turn the signal into a regular ethernet connection. Are you referring to a wireless access point?

Yesterday our internet stopped working after a storm, we didnt know if a power surge had affected our router, so we went to a thrift shop and bought the netgear CM600 for $5, not realizing that we would have to contact the isp (suddenlink) to give them the mac address or whatever of the new modem for it to even work, given that we think our existing gateway still works, so we would like to know if we can split the connection between the two instead of buying range extenders, since now given that we bought a pretty decent modem, we would like to know if we can split the connect between the two, i cant find any information from suddenlink about multiple ip addresses.

@Enemy_uav63 If you have coax in both places you want to put the modems (I assume you do), you can use MoCA instead. This puts a gigabit Ethernet link on the coax so it can go wherever you have coax.

 

If it interests you, I can walk you through it. I have it in my apartment right now and it works great.

Most likely the ISP wont let you connect (or at least use) 2 modems at the same time for the same internet connection.

What you want is an ethernet cable from the 1 working router to the new(ish) one. Which with proper settings would repeat/enlarge the wifi and cabled network.

Yeah could I have some more info on how this works?

Yeah if you get a second account, but then you would have two full fledge internet connections. 1 IP address per modem and no you cant share IP address between multiple modems. IF you have coax in both locations however you should check out a technology called MOCA. That should solve the issue right there.

It works a lot like those powerline Ethernet adapters (just better, because coax was design for data, where powerlines weren't). It's roughly the same as how the Internet get from your cable provider to your modem, but at a higher frequency (so it doesn't interfere and can be band-cut filtered from leaving your domicile).

 

To borrow from a previous post about it:

 

 

The adapters I have are both Actiontec ECB6200. This is the splitter I have. This is a decent filter.
