Why does Dial-Up Networking say that I’m connected at 115,200kbps?

Dial-Up Networking is reporting the computer-to-modem speed (also known as the Data Terminal Equipment (DTE) speed) rather than the speed that your modem connects to the modem at BT Ireland. The modem-to-modem speed is described as the Data Communications Equipment (DCE) speed.

One cause may be that an incorrect or outdated .inf file is being used for your modem (an .inf file is basically a text file that tells Windows how to set up your modem). You need to get an updated .inf file for the modem which can be obtained from the website of your modem manufacturer.


How to install an .inf file

To install the .inf file after you've downloaded it, follow these simple instructions.

  • Click on Start, select Settings and then Control Panel.
  • Double-click on Modems. (Windows 2000 & XP users double-click Phone & Modem Options. Then click the Modems tab.)
  • Highlight your modem by clicking on it once.
  • Click on the Remove button.
  • Click on Close.
  • Double-click on Add New Hardware. Click on Next.
  • You'll be asked if you want Windows to search for your new hardware. We want to specify the new modem information, so select No and click Next. (On some versions of Windows you will have to click Next first then select the No option).
  • Next, you'll need to select the type of hardware to install. Select Modem, and then click Next.
  • Windows will offer to try to detect a new modem. This often works, and is worth trying if you don't have an .inf file. As you do have an .inf file, select 'Don't detect my modem; I will select it from a list.' Then click Next.
  • Click the Have Disk button.
  • Click Browse and navigate to the folder where the .inf file is located. If you're in the right directory, the .inf file should be listed on the left side of the window. Click OK.
  • Click OK in the 'Install from Disk' window.
  • Select your modem from the list and click OK.
  • Select the COM port your modem is on and click OK.
  • Click Finish when Windows has set up the modem.
