Can two computers run off of one cable modem box with an ethernet splitter?

Answer 1

They can yes, but you will only have access to the internet on one at a time. You would need a router to have two or more computers access the internet at the same time...

Answer 2

Cable Modem Ethernet Splitter

Answer 3

I think by Ethernet splitter, you would mean an Ethernet switch. Technically, yes this is possible however most ISPs have a policy of assigning only 1 IP address per subscriber. If this is the case, the 2nd PC that will plug into the switch will not be given an IP by the ISP, hence no browsing. You will need a router instead for the 2 PCs to share the cable Internet connection. This is possible due to the router's Network Address Translation functionality.

Answer 4

First of all, I don't think there is such a thing as an "ethernet splitter" cable.

Each computer has to have a ethernet card installed, either wired or wireless, which in turn connect to a router, either wired or wireless, which then connects to the modem.

Answer 5

You DON'T want to use an ethernet splitter. What you want is an ethernet router/firewall with 2 or more RJ-45 network ports. Just plug your computers into the router/firewall. Both will be protected by the firewall, especially if you're running Windows.

For example, the Linksys BEFSR41 (4 port).

If you wanted wireless too, you'd look at the Linksys WRT54GS.

Answer 6

No, there has to be an individual IP assigned to each computer. Routers do this and you can call your ISP to set up two separate modems, but an ethernet splitter wont work.

Answer 7

Yes, I run a laptop, desktop and my xbox 360 off of the same ethernet cable using a router as a splitter.

Answer 8

Routers can do this. They are cheap.

The main thing is that your modem has an IP address that everyone out in the world can see.

But really, an IP address can only refer to one computer.

So the each computer connected to the router gets an ip address in a special range (usually 192.168.x.x) and the router translates the destination source and address of every single packet of infromation inbound and outbound.

That way you can have as many computers as you want behind one public IP address.

Of course, consider before you run out of internal IP addresses, you will run out of bandwidth before you get any crazy ideas :)

You probably want to use a router because each device will need a separate IP address. A switch wouldn't work in this case.
