Splitting a high speed cable line inquiry

Hi,

Okay, so I have roadrunner and the cable from the backyard is running under the yard up to the multilink box, where it is then router down to the basement. I want to split the line (instead of using wireless) so that I can have it run down into the basement, as well as up the exterior of the house into the 2nd floor room. Previously, I had satellite in that room, so it is already being supplied with a coax cable in the room with the cable running down and the other end "dangling" next to where the HS internet is running into the basement through the wall.

A couple quick questions:

1) I know I can buy a cable modem from newegg or wherever, is this all I need (as well as a splitter to have the internet split into two lines) and then have a network cable running into the 2nd floor computer?

2) Will this change the speed of my current house network? Right now, I have the single line going into the basement into a cable modem, and then into a linksys wireless-g router (wrt54g)?

3) Is it this simple to do, or am I missing something else?

Thank you for your input!
 
The question to you would be are you trying to set up a second system in the upstairs room or carrying a laptop around with you? Once you split a line assume that there will be signal loss and possible noticable slowdown especially when another system is added to one point on the existing router. Basically you would be splitting one channel on the same router when you use a splitter to run the extra cable needed.
 
In the basement is a desktop with the cable modem/router. In the upstairs, is my custom build. Yes, I know I can simply get a PCI adapter, but I like to try new ideas and was wondering what I will experience. So, I am able to split the line and put an adapter on one end and a splitter on the other, but that will decrease speed performance.

Is there anything else that I should be aware of?


Thanks!

On a dsl setup here with four systems connected(one being the host pc) two share one line off of the router. But the distance from the router to the splice is about 15ft. Another 10ft goes either way to reach the two systems involved. Surprizingly the speed loss isn't that much. But that is with dsl which has only a slightly heavier wiring then cable. Both systems can run at the same time without issues. But there are different browsing times as well.

So far that setup has worked well since 2004. If your basement system acts as the host you shouldn't have to split but use a secondary channel to the router itself. Are you running any other systems on the router?
 
I have road runner cable.

In my office I have the modem and a router which connects my five computers via cat5 cables. In another room I have another router (DHCP disabled) there is a 35 foot cat5 cable connecting this router to the router in my office. I almost never notice performance issues with these two computer or the computers in my office.

I would recommend running a cat5 (for the future maybe cat6) cable from downstairs to your room.
 
In this setup, I will have HQ computer in basement (with cable modem/wireless router), I have a laptop (with built in wireless adapter), and on 2nd floor is my custom build.

Currently, my router (with 5 ports in back I believe), is only using one slot, which is connected to HQ computer, and the laptop uses the wireless signal.

The main reason I wanted to "split the coax cable modem line on the exterior of the house is because of the fact that I had satellite in the room with the custom build at one point, so it has a coax outlet, running down the exterior of the house with the other end not being used, but conveniently right next to the cable modem inlet from the cable box about 50ft away from house. It is housed in a multilink grey box, and then fed through the wall to the basement.

If you could patch from the end of the cable coming down from the 2nd directly to the router you would gain access to a free port solving the problem there by utilizing a separate channel from the host pc for internet access. As a rule the host pc stands separate from any others while you could still install the software/drivers on the system you use upstairs. You would have to shut one down to run the other effectively though. Unfortunately cable isn't quite available around here yet to give you any better ideas to work with. Dsl is the fast one here over.... DIALUP?(%@$#!)
