sharing Vista SP1 laptop wi-fi with XP Pro desktop

by ranman96734 / September 19, 2008 7:47 PM PDT

I'm pretty knowledgeable when it comes to computers but despite my greatest efforts I simply cannot get this to work... here is the situation

I have a desktop sans Wi-Fi capability running XP pro SP3 that I've got hooked up via ethernet to my laptop running Vista Home Premium SP1...

My question is how can I use the wi-fi connection on my laptop to give my desktop internet?

I already have my Wi-fi connection set up to be shared... I've tried manually setting the IP addressed to something like and and then setting the gateways to each other... that didn't work... and I've finally given up, any help would be appreciated.

Re: sharing Internet

Two ways:

1. The software way (use Internet Connection Sharing=ICS) on the Vista laptop. Details, for example, in

2. The hardware way: Add a wireless card to your desktop, so it can run independently of the laptop. Here's one:
Note this is not a recommendation for the seller nor for this particular product. You can find many comparable products (also connecting to USB, if you prefer) and all shops have them.

If you already have the wireless router, I'd recommend to go the hardware way. ICS, although working, is somewhat outdated (it used to be useful in the good old days of dial-up).

Hope this helps.

I'm trying to use ICS, not interested in the hardware way of using money... I'm having trouble getting ICS to work thought that's what I was asking for help with.

That was what you were asking for. So I gave a helpful link.

But I couldn't resist telling about the currently preferred alternative.

Anyway, I hope you get it up and running. It's certainly possible.

Possible but the lesson on ICS is

It doesn't always work, is finicky and some never get it to work. The number one and two reasons I find it to not be working is the firewall and the second is the owner doesn't have a grasp on TCPIP and networking in general.

Can anyone help with the problem?

So, thanks I've got a good understanding of TCP/IP I mean... I don't know what SYN/Ack packets do or anything but I know what a subnet is and how to set up a VLAN... so yeah... I think it has something to do with the services running or not running, I just don't know which ones.

I'm not interested in any alternatives, I only use this desktop to do 3D editing and the only time it's connected to the internet is when I need to download a new program, so buying another wi-fi card or adapter isn't something I'm really interested in...

Just want to have my desktop use my laptops wi-fi...

I've tried just about everything... It's something with the desktop I think... I'll post here if I figure it out

Any clues could offer an idea.

In reply to: Hmm

You didn't tell how you wired it up or what cable you used and more. No details about if the other machine got it's IP and more.

I have a cross over cable and regular ethernet cable, neither worked, I have let them configure automatically and tried setting to and and setting their gateways to each other... the desktop has two ehternet jacks a nvidia nforce whatever and a marvel yukon, the drivers are up to date. I've tried the connection from both. I've restarted both computers, enabled and disabled connection sharing, it appears that the desktop can recieve packets but can't send anything out.. the laptop has stuff going both ways, the event manager doesn't show any errors.

I've also tried setting up a network bridge.

On the laptop side I have NVIDIA nForce Networking Controller... and the wi-fi adapter is a broadcom something something.

I'm going to buy a wi-fi adapter. **** this.
