You should be able to just disable one which would automatically make the other the default connection. Go to Control Panel and open Network Connections. Then Highlight the one you don't want to use and right click and you will see a box with some options. Click Disable and it will put an X through that connection making the other connection the default or the one you wish to use.
I use my laptop in my office and at home.
In both cases I have a LAN connection.
The ISP in the office is of course different from the
one at home.
I tried to install both and have Windows XP recognize
in each case the one that is active. But Windows doesn't
acknowledge the second one, unless I remove the first.
Is there any way to have both on the computer at the same time and then activate the one required in each case (office or home)?
