How to use dual networks on Windows XP?


 Share

Question

Dell Optiplex Windows XP system with on-board ethernet and add-on PCI wireless card.

The PCI wireless is connected to the Internet via ISP provided wireless router.

The on-board ethernet is connected to the LAN.

Only one connection works at a time, i.e. when I plug in the ethernet cable, the wi-fi stops working, and vice versa.

How can I get both to work simultaneously?

Wi-fi Adapter:
IP: 192.168.1.10
Default Gateway: 192.168.1.1
Subnet Mask: 255.255.255.0

Ethernet Adapter:
IP: 192.168.0.2
Default Gateway: 192.168.0.1
Subnet Mask: 255.255.255.0

 

Googling this turns up a plethora of conflicting advice.

Hopefully, someone here can straighten this out.

Not my forte but do you want the LAN to only work for local file transfers or is it another ISP connection?

 

You could proably remove the default gateway from the LAN (i think) or set some priorities in the properties of the WLAN connection?

Yes. The LAN is only used to share files locally.

Then as Roger correctly stated already just remove the gateway from that network interface, since it has no "gateway" off the 192.168.0.0/24 network.

When you say stop working - What exactly do you mean?

 

NIC / WLAN adapter show as disconnected? or pings drop to devices on each subnet?

It doesn't disconnect. There is simply no response when trying to access shared folders on the LAN, and Firefox says "Page cannot be found"

Then as Roger correctly stated already just remove the gateway from that network interface, since it has no "gateway" off the 192.168.0.0/24 network.

 

OK, will try this a.s.a.p.

Bah had to login on firefox to be able to paste links in this WYSIWYG editor >.>

Seems to be what Budman and Roger says. Will try and report.

It's at one of my client's office.

Are the computers on the LAN side connected to the internet?

 

If not, use could use Internet Connection Sharing (ICS) on the Win XP machine.

That way your internet access will work and the LAN side will have access to your PC and the internet.

The faster connection should be the connection Windows uses. This is usually the Ethernet connection. I "think" you need a server OS to use both.

No. It's purely for file sharing.

Remove the Gateway and DNS on your LAN. I have this setup for one of my servers at home (two internet connections)

 

Wireless - DHCP

LAN - Static IP address and Subnetmask (No Gateway and DNS)

 

While im not using Windows XP. I think you should be fine with this setting.
