one computer, 2 NICS to 2 networks

Specs: WIn XP, 2ghz/1gb

Hi,
I have a computer with a wireless NIC and a ethernet card. I am connected using the wireless NIC to my home wireless network(192.168.0.0, Linksys router). I want to have a seperate wired LAN in my room for my different computers though(192.168.2.0, Belkin router). I run Win XP by the way. The problem is, when one network works, the other doesnt. How to I make both of them work at the same time, so that I can browse the web on the wireless LAN and do my data transfers on the wired LAN at the same time.

Thanks

Try removing the Gateway Address from your NIC's and both should work.

Yet another interesting question... I had to think about this one (and still am). I know that this question is going to nag me at work all day.... THANK YOU VERY MUCH!!! My family is already considering a devorce over the time that I spend at this keyboard.

You could link the two routers together with a common gateway to accomplish your task (see the linksys manual for this) but then you would pretty much be creating one large network, thereby defeating the purpose.

You could try and create a BRIDGED connection between your wireless and wired, (but back things up first because I have a feeling your system will become unstable.) But I think even with this, in a round about way you would again be creating one large network.

When you come down to it, xp needs to know how to direct traffic and it does this by keeping the 2 networks separated to the point where one is the DEFAULT connection and one is the ALTERNATE. If you think about it, even though XP can log 2 user accounts in at the same time, they cannot be USED at the same time....

and to the best of my knowledge, this can not be changed.

If I wake up in the middle of the night with a better answer, I will be sure to let youknow.

This is a very common setup in servers but I think you must ensure you use a different sub net, so try setting the ethernet connection to 10.10......whatever & keep away from the wireless network range but this means the second computer cannot share the Internet connection unless it too has effectively two nics, one on the 192... net and the other on the 10.10......
I have something similar installed, I have a laptop which is wirelessed to my desktop for ICS but the ethernet on my laptop is hard wired to a desk top which I use to back up my laptop but of course the backup machine is not visible to the wireless desk top so only the laptop can see both machines.

Before anyone asks, yes, I do use the Backup machine to back up the Desktop by mapping a network drive from the laptop to the Backup, put a share on it and log into it from the Desktop. Using Ghost I keep an image of the Laptop & the Desktop on the backup machine and I keep an image of the Backup machine on the desktop working on the theory I can't lose two machines at the same time but belt and braces I copy the relevant images to DVD for restoration, works for me.!

Bob:

Can you see and confer with both networks at the same time... in other words can you perform background tasks on one network while while (for example) surfing the net on the other?

Yes, no problem, you just need a decent amount of RAM re my post on AVI files which you kindly reminded me of the file size limits on FAT32 (Thank You!) I can easily upload a 15GB file to my backup machine while downloading another file from the web, the task manager does look kind of busy mind you but that's what XP is supposed to do.

Bob's got it right. You have to bridge the two subnets and you can't bridge the two same subnets. Routing wouldn't know which way to go.

BTW, this a real "cheapy" network, no hubs etc, I use a X-over cable from Laptop to Backup machine, very fast too!

The original post complains that one network stops working so he reports.
I am pretty sure it should work fine.

I'd start with event viewer. Not all nic drivers support XP fully.
I'd be sure to disable ICS too if you use it.
As to why else. Do you use internet explorer to access the backup drive? Be sure to make a link to the backup drive from network neighborhood.

Hi Guys,
Thanks for the responses. I tried Bob's suggestion and changed one of the networks to 10.10.2.0 subnet. It worked! Thanks to all the respnses.
