What Is a Modem Driver?
A driver is a software component that goes along with a physical device, such as a modem, that enables an operating system to utilize the device properly. Sometimes a driver needs to be updated to stay functional.

Function
-
Modem drivers are instructions that tell an operating system how to use it. Drivers are often specific to a certain operating system.
Upgrades
-
Drivers for hardware devices are often upgraded to optimize performance. Checking for upgrades periodically is important to ensure all devices are functioning at their best possible level.
-
Sources
-
Upgrades for certain devices may be released by the manufacturer or by third parties. It is always safest to get official driver releases.
Issues
-
Installing a bad driver can cause a device to malfunction and can cause system instability.
Rolling Back
-
If a new driver causes a system to malfunction, the best thing to do is to reinstall or "roll back" to the previous driver and look for a different upgrade.
