Cross-Over Connections?

Agravehra · Post by **Agravehra** » Sat Sep 02, 2006 9:58 am

I am currently living in an apartment that has a single Cogeco cable connection for all the residents which we connect to over a wired local network. The problem I am having is that in my office I have two computers that I want to connect to the internet, but only outlet in the wall that I can connect to.
My first attempt at this problem was to connect my D-Link AirPlus Extreme G Wireless Router (DI-624) to the local network and then to connect both of my computers to the router. While the router recognized both its connection to the WAN and to the computers it would not allow the internet connection to pass through itself. I had someone suggest to me that I should disable the DHCP on the router, which I did to no avail.
My second attempt at this problem was to purchase a second network card for the one computer, plug it into the outlet and then use a cross-over cable between the two computers. In this case all I got was internet on the one computer and a message on both computers that there was limited or no connectivity between them on the second network connection.
I currently run Windows XP Home: SP2 on both computers and if anyone could help me with my problem it would be greatly appreciated.

Thanks

Hello,

To get the crossover cable technique right you'll need to bridge the LAN connection with the crossover connection on the computer with the 2 network cards.

So you know those moments when you are fixing a computer for someone and they tell you "I tried that, but it didn't work for me" and then you tell them that it worked because the computer was scared of you...well this is one of those moments. I had already tried bridging the two connections, but it didn't work so I undid it and forgot about it. Now it seems to work. I have no idea why, but thanks Craig for scaring my computer into submission.

Ok, I'm assuming that since your whole apartment building is sharing one internet connection that you all have private IP addresses, right? It could be that the router is trying to assign IP addresses from the same net or subnet as is already running through your building, for example 192.168.1.x. If that's what your building uses, then just set your router to assign addresses from 192.168.2.x instead, and you should be fine.

I second that hunch....log into the routers web admin, compare WAN address with LAN address.
