Trying to connect two computers to the internet, one says that there is an IP address conflict. Why?

Home » Networking

Hi, I want to connect my desktop and laptop to a LinkSys hub so that I can access my high speed DSL internet on either computer, often simultaneously. However, my laptop says that there is an IP address conflict and subsequently disables the connection. How can I fix this problem -- I can't get another ISP, so I have to share this IP address.

To start with, if you're truly using a HUB and not a Router then that's 90% of the problem right there. A router of some sort is required to share a single internet address among multiple computers. It's fairly easy, and they're not terribly expensive.

The other 10% sounds like it might be configuration issue. I would double check the TCP/IP configuration to ensure that it is set to "automatically receive an IP address".

You have to configure the PC's (that have Internet connection only) "C:\WINDOWS\system32\drivers\etc\networks" file so that it will act as a DNS server.

Introuduce the both Ethernets network address in that file.

For example,
Middle Desktop-Pc have 2 Net Cards.

Internet(172.14.13.2)(172.14.13.3)PC-Desktop(172.14.14.4)(172.14.14.5)Notebook

Step1: Now add this two networks(172.14.13.0 & 172.14.14.0)in the Desktop-Pc's "C:\WINDOWS\system32\drivers\etc\networks" file.

Step 2: Desktop-PC side Net card that is connected with your Notebook, go the TCP/IP configuration Properties, use (172.14.13.3) as a DNS and gateway address also.From Advanced TCP/IP Settings make this gateway priority 1.

Step 3: Notebook net Card, go the TCP/IP configuration Properties, use (172.14.13.3) as a DNS and gateway (172.14.14.4) address also.
