2 networks 1 house

[Beaker491]

Hello

Is it possible to have 2 seperate computers wired up to seperate 2 routers, to make 2 different networks, using one phone line? I.e one computer wired into a router downstairs, in one phone socket (lets say "Network A") and another computer wired into another router, in another phone socket, upstairs (Network B)?

Thanks

Ian

Um ... why would you need two separate networks in the same house?

If your going through phone sockets, then i assume your either, looking for 2x dialup connections, only much use if you have 2x phone lines.

Or

Your trying to split something like BT broadband between two routers.

I know that with virgin I have 3 cables comming from the outside box, into my home, and I can swap the 2x boxes and modem onto any line and still get the tv/net on each one.

If you want two groups of PC's to use two different networks, then you just need to set up two different network names. Your default windows network name should be "workgroup" just change the settings on the PC's that need a second network, so that they have their own network name.

Or are you trying to keep these networks completely independent ie, work / home internet? in which case, just get a second connection, with its own modem/router and plug in the PC's you want.

Its a shot in the dark without more info on what exactly your trying to achieve.

I'm not sure if I understand what you're asking for, but you can set up two subnets with two routers on one internet connection. The two subnets will be separate networks. A computer on subnet A will not be able to see or communicate with a computer on subnet B. The same goes vice versa.

If that's what you're trying to accomplish then you could try this.

Here's how the connection between the devices will look (see below). Use ethernet cable to connet your internet connection to routerA's wan(internet) port. Then use ethernet cable and connect routerA's lan port to to router B's wan(internet port).

internet connection ------> routerA -------> routerB

Before you connect the routers. In routerA, set the local ip address to 192.168.1.1. After that for router B set the internet connection type to "static" with IP address of 192.168.1.2, subnet mask of 255.255.255.0, and "Default Gateway" and "DNS address" to 192.168.1.1. Then set the local Ip address of routerB to 192.168.2.1.

Note - You might need to set your DNS address of routerB to the same DNS address of routerA.

I hope that's not too confusing.

Your ISP has to assign a 2nd IP to your cable/dsl modem. (some ISPs do this for free, mine does)

My setup is like this:

Cable Modem
|
switch ___ router 1 --- network 1
|________ router 2 --- network 2

Both routers are DHCP and get the unique IPs from the ISP. Works flawlessly.

Is it possible to have 2 seperate computers wired up to seperate 2 routers, to make 2 different networks, using one phone line?

Yes, but only one router can act as the WAN gateway i.e. the one connected to your master telephone socket. As you're in the UK and mention "phone line" I'm assuming that you're on an ADSL connection of some sort?

I.e one computer wired into a router downstairs, in one phone socket (lets say "Network A") and another computer wired into another router, in another phone socket, upstairs (Network B)?

Nope, that won't work. The "B" router would have to be connected to the gateway router either via ethernet or as a wireless bridge; network traffic can't be routed via the internal telephone wiring.

If your aim is simply to keep the two computers seperate, check if either router offers a VLAN (virtual LAN) facility. This will allow each to be isolated from the other while still sharing the WAN (internet) connection.
