The Dell Wireless 5720 VZW Mobile Broadband (EVDO Rev A) Minicard Status Port (COM4) driver helps Windows recognize the status-monitoring interface of Dell’s mobile broadband minicard. It allows compatible connection-management software to communicate with that interface, which is part of the modem rather than a separate network adapter.

Key Features

• Status-port recognition: Identifies the minicard’s status interface in Device Manager, helping resolve an unrecognized device when the correct driver is installed.
• Communication with modem software: Provides the serial-port interface that compatible Dell mobile broadband utilities can use to access modem status information.
• Support for the broadband driver setup: Works alongside the minicard’s other driver components; the status-port driver alone does not provide a complete mobile data connection.
• Windows configuration: Enables Windows to assign and manage the interface as a COM port. Although this device is listed as COM4, the assigned port number may differ between systems.

How to Install

1. Verify the hardware. Open Device Manager and locate the Dell Wireless 5720 status port or the corresponding unknown device. Check its hardware IDs under Properties > Details to confirm that the downloaded package matches your minicard.

1. Check Windows compatibility. Select a Dell driver package appropriate for your operating system and architecture. For Windows 11, 10, 8, or 7, verify the package’s stated support before installing; this legacy hardware may not have an officially supported driver for every version.

1. Download and extract the package. Save the driver locally and extract it if necessary. If you are replacing an existing working driver, consider creating a restore point first.

1. Install the driver. Run the included installer and follow its prompts. If no installer is provided, right-click the device in Device Manager, select Update driver > Browse my computer for drivers, and point Windows to the extracted folder.

1. Restart and verify. Restart if prompted, then check that the status port appears without a warning icon. If you use compatible broadband-management software, confirm that it recognizes the modem.

Installing this driver does not guarantee cellular connectivity. The Dell Wireless 5720 relies on legacy EVDO/CDMA service, so network availability, carrier support, and any required companion drivers remain separate requirements.

Common Issues and Fixes

• Install fails or rolls back: Run the Dell Wireless 5720 driver package as administrator. If Setup still fails, open Device Manager, right-click the unknown “Status Port”/WWAN device, choose Update driver, and point it to the extracted Dell 5720 driver files.
• Device not detected / COM4 missing: Confirm WWAN is enabled in BIOS and airplane mode is off, then reseat the Minicard. In Device Manager, check for unknown devices or a hidden COM port; remove stale COM4 entries and rescan.
• Version conflicts: Uninstall older Dell Wireless 5720 and Verizon VZAccess drivers first, delete the old driver when prompted, reboot, then install the matching Dell package. Avoid forcing a generic modem driver onto the Status Port.
