The configuration of your modem, its drivers and firmware can have a significant impact on the stability of your connection. Every modem is different, with some better than others, however you should be able to achieve a stable connection regardless of the type you have. This section is designed to make sure that everything relating to your modem is correct and up to date. Just make sure you follow the correct instructions for your operating system! Note that you do not need to be online to do any of this.

Wrong modem drivers

Info: Modem drivers or scripts are what your operating system uses to control and work with your modem. If you have the wrong modem driver installed, your operating system can have problems working with your modem, and even if it connects you might find you have dropout or throughput problems. With the wrong drivers, your modem is most likely not working to its full potential.
Investigation: You need to check which driver is installed for your modem.
Windows 95/98/Me: Go to Start -> Settings -> Control Panel. Double-click on Modems. Ensure that your modem name is listed. If not, you will need to install the correct drivers. Note that any driver marked as Standard (eg. Standard Modem) is a generic Windows driver and is therefore NOT the correct driver.
Windows 2000/XP: Go to Start -> Settings -> Control Panel. Double-click on Phone and Modem Options. Click on the Modems tab. Ensure that your modem name is listed. If not, you will need to install the correct drivers. Note that any driver marked as Standard (eg. Standard Modem) is a generic Windows driver and is therefore NOT the correct driver.
MacOS: Go to the Apple menu -> Control Panels -> Modem. Ensure that your modem name is selected. If not, you will need to install the correct modem script.
Solution: A driver disk or CD and some instructions on how to install the drivers should have come with your modem. Remove the wrong driver and install the correct one as specified in those instructions.

Old modem drivers

Info: If you have the correct drivers, but an old version, it is possible that a newer version has been released by your modem manufacturer. New drivers often have fixes for connection related issues that might help with your problem.
Solution: Check your modem manufacturer's web site for a new version of your modem drivers. Download and install them as per the instructions that should be on the site. This simple step can give you much more stable connections, especially with internal modems.

Modem firmware

Info: If you have an internal 56k modem, you will have already covered this step above when you updated the drivers. If you have any external modem, or an internal 33.6k (or slower) modem, it is definitely worth doing.
Solution: Check your modem manufacturer's web site for a firmware (or flash) upgrade. If they have one that is more recent than the manufacture date on your modem (or when you bought your modem), download and install it according to their instructions. A word of caution: firmware upgrades work by writing to a chip inside the modem. If you use the wrong firmware, or anything goes wrong, it can render your modem useless. If you are unsure at any stage, contact your modem manufacturer for assistance.
