My house is wired with cat5 wires all throughout the house and I have a DSL internet connection. I was wondeing if there was any way I could add a second modem. The 1st one is down stairs and is connected to a router which is sending wireless to the house, but I want to have an ethernet connection to my new computer, so I rewired the RJ-11 port in my room for the DSl and was going to plug another modem into it. My question is will this work and if so will it affect the bills?

typically, one modem means one internet connection. Modems may have the ability to switch between multiple internet accounts but don't think that's what you want.

Wheres the phone line now, down stairs or in the room you just rewired?

If your house is wired with cat5 already, it would make more sense to have the dsl router in one location (downstairs was it originally?) and feed internet to rest of the rooms via network cable.

two dsl modems will not work simultaneously. Only way is to have two separate accounts paying more money and have the modem's alternating each account.

I'm confused though, if your house is wired cat5 already, just use that instead. Connect the cables to the router.

the problem is I don't understand how this works. The cat5 wires all carry the DSL and phone connections so how would I run the connection through my modem/router to my room without having to strip my dry-wall

I want the connection to be wired not wireless I have a wireless connector but its not reliable because of interference from my floor, also boosters are out of the question

Alright, picture below is of a modem+router bundle with wireless. Hopefully will give you some idea what i mean.

If this looks similar to your router, you should have a series of network ports, those numbered in picture 1 to 4. It would help if you knew where the cat5 cables lead to in your house and where the point of origin is. The idea is to connect the cables from the rooms to the back of the router.

I have a network setup here at home and where the modem/router is i have a wall plate with multiple network ports spreading to each room where they each have a single network plug each.

so i plug an Ethernet cord into where all the cat5 cables are based and the the network is spread through out the entire house

Without knowing exactly how the house is wired, all we can say is "probably".

There would have to be a switch somewhere in the house, distributing the ethernet signal to the various rooms.

if I only want to distribute it to one room would I still need a switch?

Well...you'd run one Cat5e from your router to that one room.
But as the house seems to be already wired....where does the wire that already exists in that particular room actually go to?

No you can't just plug in a ethernet in to a live phone line it would probably blow the modem ports you have to disconnect the cable from the phone line and wire a rj45 socket to each end, each Ethernet socket needs a port on a modem, router or switch.

Once you have put on rj45 sockets you can get a plug in adapter that you plug in both ends that uses 2 wires for phone if you need it.
