The In-Build Conexant SIS AC '97 Modem driver helps Windows recognize and communicate with this integrated dial-up modem. It is intended for users restoring a legacy computer, reinstalling Windows, or troubleshooting a missing modem in Device Manager.
Key Features
- Modem recognition: Enables Windows to identify the integrated Conexant SIS AC ’97 modem and make it available to compatible communications software.
- Dial-up connectivity: Provides the software interface needed for a dial-up connection when used with a working telephone line and an appropriate service provider.
- Legacy system support: This Microsoft-listed Network device has Windows 10, 8.1, 7, Vista, and XP listed as supported operating systems. Individual driver packages may support only some of these versions.
- Driver maintenance: Installing a matching package can help resolve problems caused by a missing, damaged, or incorrectly assigned modem driver.
How to Install In-Build Conexant SIS AC '97 Modem Driver
- Identify your hardware and Windows version. Open Device Manager and locate the modem or unidentified device. Under Properties > Details, check its hardware IDs. Also confirm whether your Windows installation is 32-bit or 64-bit.
- Choose a compatible package. Before starting an In-Build Conexant SIS AC '97 Modem driver download for Windows, compare the package’s supported hardware and operating systems with your computer. For Windows 10/11 searches, note that Windows 11 is not included in the listed support information; do not assume compatibility.
- Download and prepare the files. Use a trusted source for a free download, and extract the archive if necessary. Check the package documentation and create a restore point before replacing an existing driver.
- Install the driver. Run the supplied installer, if available. Otherwise, right-click the device in Device Manager, select the driver update option, and browse to the extracted driver folder. Avoid forcing installation if Windows reports a hardware mismatch.
- Restart and verify. Restart your computer if prompted, then check Device Manager for warning symbols. Test the modem with your dial-up software and a connected telephone line.
Keep the driver updated when a compatible release addresses a problem or supports your system configuration. The latest version is not necessarily the best match for older hardware, so review compatibility before you update and retain a working driver copy for recovery.
