Problem using ICS & Ethernet Card at same time

[wseyller]

Only internet connection I have is by using my windows mobile phone via internet connection sharing through usb.

I now have a wireless router to use only for file sharing between computers and for wireless printing. I do not have an internet connection on this network.

Problem is if I enable the Local Area Connection for the Ethernet Card then it causes my internet via the phone to cease. As soon as I disable it again then webpages load again.

How can I get both working at the same time.

My computers use Windows XP Pro SP3.


Also This is my ipconfig:


Windows IP Configuration

Your two cards are on tow independent Network.

Network one, 192.168.0.x

Network two, 192.168.2.x

So, they are working only one at the time they way it should.

I have change the router settings. But I still behaves the same way. When Local Area Connection is enabled the web pages won't load. Once I disable it the webpage instantly loads.

remove the default gateway setting from your Realtek LAN adapter

 

[wseyller]

Just so I understand do you mean I should...

Change TCP/IP setting on my Realtek card. Instead of using a dynamic address and obtaining ip automatically, I should set a static ip manually and just leave the gateway ip blank? What about preferred dns server...normally I would set it to the same address as gateway ip....should I leave it blank too?

Yes to all of that.

Go back to where you started. But you need to remove the Default Gateway for the Realtek adapter. The Default Gateway, for your purposes, tells the PC where to go to find the Internet. You aren't supposed to have two Default Gateways set. Windows will choose one and ignore the other. If it picks the wrong one, you are in trouble.

As soon as you enabled the Realtek NIC, your PC thought it would find the Internet at 192.168.2.1. If that's not a route to the Internet, then bye, bye Internet.

Now that you have two Ethernet adapters on the same subnet (i.e. 192.168.0.2 and 192.168.0.102), your PC won't know which one to use to access the Internet or anything else on your network. When it tries to go to the Internet, it doesn't know if the Default Gateway (the Internet) is connected to NIC 1 or NIC 2.

If you want to keep both adapters on the same subnet, you can manually add Routes to your PC to tell it which NIC to use for which destination. But what you had originally should work without any special routing commands, as long as you get rid of the second Default Gateway.

Being on the same subnet 192.168.0.2 and 192.168.0.102 and then removing the default gateway but it did not resolve the issue.

I put the settings back to 192.168.2.2 and 192.168.0.102 and then removed the default gateway. Now it works. Thanks.
