Fax-capable Modem (inbox driver)

A fax-capable modem is an analog modem that can also send and receive faxes, and Windows Fax and Scan drives it through the same inbox modem driver. These live on in offices and clinics that still send documents over a phone line, and they rarely need any manufacturer software. If faxing fails, confirm the modem is detected in the Modems section and that Windows Fax and Scan is pointed at the right device.

Use this when you are not certain which family your hardware belongs to.

Dell

Dell Wireless WWAN / Mobile Broadband (OEM package)

This is the cellular broadband module Dell fits into its business laptops so they can reach the internet over a carrier network without Wi-Fi. Dell validates the driver against a specific system and often pairs it with ControlVault or module firmware, so the package tied to your Service Tag is the one to trust. Because the same module can carry different carrier approvals across models, resist the urge to substitute a newer build from the chipset vendor.

HP

HP lt-series Mobile Broadband (OEM package)

HP markets its integrated cellular modems under lt-series names, and they turn EliteBook, ProBook, and similar laptops into typically connected machines. The driver HP publishes for your product number is tuned to work with HP Connection software and the module firmware, which is why a generic download often connects to a tower but does not reliably pass data. Enter your product or serial number to be sure you get the release meant for your exact chassis.

Lenovo

Lenovo Integrated Mobile Broadband (OEM package)

Lenovo builds mobile broadband into many ThinkPad and select IdeaPad models, and the driver is looked up by machine type rather than by a simple model name. Lenovo frequently bundles firmware with the driver, and the two are meant to be applied together, so grab the whole package for your machine type. If your ThinkPad has a SIM tray but no cellular option in Settings, a missing Lenovo driver is the usual cause.

ASUS

ASUS Mobile Broadband Module (OEM package)

This covers the cellular modules ASUS installs in its business and premium laptops so users can work off Wi-Fi. ASUS posts the driver on the support page for each specific laptop, and because ASUS uses several module suppliers across its range, the download is model-specific rather than universal. Confirm your exact laptop model before installing, since the wrong build can leave the SIM unread.

Acer

Acer Mobile Broadband Module (OEM package)

Acer offers cellular connectivity on some TravelMate and higher-end laptops through an embedded WWAN module. The correct driver is the one Acer lists for your model or serial number, because Acer sources modules from more than one vendor and only the matched build carries the right band and carrier settings. Treat Acer support as the source rather than a general driver from the silicon maker.

Microsoft Surface

Microsoft Surface WWAN Module

Certain Surface Pro and Surface laptop models ship with an LTE or 5G module that lets them connect over a carrier network anywhere with signal. Microsoft services the driver and firmware for these modules through Surface support and Windows Update together, so keeping the device current usually keeps the modem healthy without a separate hunt. If cellular is missing after a major update, the Surface driver pack is the place to restore it.
