I have an USB HSDPA modem, and I configured a Dial-up connection to use this
modem.
The issue is, when I unplug the USB modem, the connection is set to the internal
56k modem (a Motorola onboard). This causes most times, when I want connect
again using the USB modem, Windows XP can't connect because it uses the incorrect
modem.

How to make it so, when I unplug the USB modem, Windows XP doesn't change the settings
of the connection?

Here are a few things to try:

- Don't unplug the USB modem.
- Remove the internal modem.
- Open Internet Options, Connections tab, remove the dial-up modem from
the list, or change to "Never dial a connection".
- Go to Device Manager, locate the Dial-up modem, right-click the modem,
click "Disable".
