The Conexant HDA D110 MDC V.92 Modem driver allows Windows to recognize and communicate with this internal dial-up modem. It supports the connection between the modem hardware and compatible communications software, helping you access telephone-line internet services where a dial-up connection is still available.

Key Features

• Hardware recognition: Identifies the Conexant modem in Device Manager so Windows and compatible applications can access it.
• Dial-up connectivity: Enables modem operation over an analog telephone line using V.92 capabilities, subject to your telephone service and internet provider.
• Application support: Provides the driver interface needed by compatible dialing and modem communications software.
• System-specific setup: Installs the components required for the supported hardware configuration. For Windows 11, 10, 8, or 7, verify that the selected package explicitly supports your Windows version and system architecture; older modem drivers may not work on newer systems.

How to Install

1. Confirm the modem and Windows version. Open Device Manager and look under Modems or Other devices for the Conexant HDA D110 MDC V.92 Modem. If it appears as an unknown device, check its hardware IDs under Properties > Details before choosing a driver.

1. Check package compatibility. Select a Conexant driver intended for your computer model, Windows edition, and 32-bit or 64-bit architecture. A package for Windows 7 or 8 should not be assumed compatible with Windows 10 or 11.

1. Extract and install the driver. If the download is compressed, extract it first. Run the included installer with administrator permission and follow the prompts. If no installer is provided, right-click the modem in Device Manager, choose Update driver, and browse to the extracted driver folder.

1. Restart if prompted. After installation, return to Device Manager and confirm that the modem is listed without a warning icon. If Windows rejects the package, look for a compatible, signed driver rather than disabling security protections.

1. Configure and test the connection. Connect the modem to a suitable analog telephone line, then enter your dial-up provider’s access number and account details in your connection software. This modem does not replace an Ethernet or Wi-Fi adapter, and the driver alone does not provide internet service.

Common Issues and Fixes

• Install fails or rolls back: Run the installer as administrator and in compatibility mode for the package’s Windows version. Remove any existing Conexant modem entry in Device Manager first; if the driver is unsigned, temporarily disable driver signature enforcement.
• Modem not detected: Enable the internal modem in BIOS, confirm the HDA bus/audio driver is installed, and check Device Manager for an unknown “Conexant HDA” device. If nothing appears, verify the MDC modem is enabled/present.
• Version conflicts or Code 10/31: Uninstall old/generic Conexant or Microsoft modem drivers, delete the driver package, reboot, then install the exact D110 MDC V.92 package. Do not force an AC97 modem driver onto this HDA device.
