I posted this in the LAN/WAN section by mistake, figure I'll get more of a response here:

First of all, here's my setup:

Computer A: Windows XP Pro, connected to router wirelessly, internet connection is shared.

Computer B: Windows Vista 32bit, connected to Computer A via a crossover cable.

This was working fine for several weeks (ever since I installed vista) until today. I updated my chipset drivers on Computer A, and now Computer B will not connect to the internet through it. I never could get file sharing to work properly between the two, but I was fine with that as long as I could connect to the internet. When it was working, I had Local Area Connection 1 and 2 on Computer A on a network bridge. I'm a total noob when it comes to networking, I don't even know what a network bridge is or does, but it worked. Now that the comps won't connect anymore, I deleted the bridge. I've tried setting up static ip's...no joy. They are both on the same workgroup. I can't seem to find anything on any forums that is similar to my situation. If you need more specifics, just ask. I will be monitoring this thread intently and impatiently.

Just when I thought I was starting to get a handle on XP networking, Vista comes along and makes things difficult!!

This is not a definitive answer but guesses. Try in this order:

1) Find out brand and model/series of your chipset. Google "<brand/series/model> chipset update stop network" or "<b/s/m> chipset problem" or "<your motherboard> chipset network" or some more combinations with creative keywords. Note the more words in your search, the less likely Google will pull up close solution

2) Go to Control Panel > System > Hardware Tab > Device Manager > go to chipset driver you just updated. There you should see "Rollback to Previous Driver" button. Click to roll back to your old driver.

3) Updating the chipset drivers shouldn't alter your network status. The only thing I can think of is that I read some time ago that Nvidia chipsets have some sort of firewall built into them. I wonder your chipset update put up a firewall at your network cards. Not saying you have Nvidia chipset but other vendors might follow Nvidia way

4) Or is it due to Windows (XP/Vista) unpredictable behavior???

Let me know how it goes. Maybe somebody can give more accurate answer???

Yea, I think it's more vista related. I can hook up another XP computer and they see each other no problem - file sharing, ICS, no problems. The Vista machine just decided that all the sudden it can't find the network. I really wish they would have included Network Setup Wizard on Vista. And yes, I do have a Nvidia chipset on both machines. The one I updated on the XP machine is nForce 570 SLI, and the Vista machine is nForce 430. When I install chipsets, I always make sure not to install Nvidia Network Access Manager, that is the built in firewall. I think I'm just gonna roll the Vista machine back to XP.

i didn't get it in the beginning too.
well you have router CD right? what you have to do is.. you install on xp router, and when you install on vista you have to specify it is older OS or newer i don't really remember where, but you have to look for that. it should work. at least you will get to somewhere
