What is dlink-assistant.exe?
dlink-assistant.exe is the executable for the D-Link Assistant utility that helps you discover, configure, and monitor D-Link devices on your local network. It runs as a background service with a lightweight UI to simplify setup, firmware checks, and provisioning for supported devices.
