## Summary description

D-Link DUB-E100 is a USB 2.0 Fast Ethernet adapter that adds a 10/100 Mbps wired network port to compatible computers. It features an embedded 7K × 16-bit SRAM buffer and energy saving suspend/resume function. Supported operating systems include Mac OS X and Microsoft Windows. Suitable for desktop or laptop use when native Ethernet is unavailable or damaged.

## Long description

The D-Link USB 2.0 Fast Ethernet Adapter DUB-E100 provides a 10/100 Mbps wired network interface via a USB 2.0 connection, enabling computers without a functioning Ethernet port to connect to wired networks. The adapter includes an embedded 7K × 16-bit SRAM buffer to handle packet bursts and an energy saving suspend/resume function to reduce power consumption when the host is idle. Compatible with Microsoft Windows and Mac OS X, this compact adapter is designed for desktop and laptop systems that require a reliable Fast Ethernet connection.
Advantages
The adapter delivers stable 10/100 Mbps Ethernet connectivity through a USB 2.0 port while offloading temporary packet storage to an integrated SRAM buffer, which helps maintain throughput during traffic peaks. The energy saving suspend/resume feature minimizes power draw when the host system enters sleep states, and the small, portable form factor makes it easy to carry and install without internal upgrades. Driver support for common desktop and laptop operating systems simplifies setup and integration into existing networks.
Suitable for
Adding a wired 10/100 Mbps Ethernet port to laptops and ultrabooks that lack a built-in Ethernet jack
Replacing a damaged or non-functional onboard Ethernet port on desktop or laptop computers
Providing a quick wired connection for devices that currently rely on wireless networks for configuration or troubleshooting
Temporary or mobile workstations that need reliable, low-latency wired connectivity

How to use
Connect the adapter to an available USB 2.0 port on the computer and attach a standard Ethernet cable to the adapter's RJ-45 port and the network outlet or switch. Install the appropriate driver for your operating system if prompted; many systems detect the adapter automatically. Once installed, configure network settings through the operating system's network control panel or system preferences to obtain an IP address automatically via DHCP or set a static IP as required by your network.
Usage recommendations
For reliable performance, use a USB 2.0 port rather than a legacy USB 1.1 port and connect the adapter with a quality CAT5e or higher Ethernet cable. If using power management features, verify the host system's suspend/resume settings to ensure network reconnection after sleep. Keep drivers up to date for best compatibility with newer OS updates.
