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".

I'm traveling in my RV. I have an wifi internet conection on my lap top that I would like to share the internet connection with a desk top compute at the same time. Wife works on one computer I work on the other. How do I accomplish this.

The simplest is with an ethernet cross-over cable connected between the two machines, and turning on "Internet Connection Sharing" on the laptop.
