FAQ
What type of USB port does this Ethernet adapter require?
The Dell DBJBCBC064 Gigabit Ethernet Card requires a USB 3.0 port for optimal performance. While it may function in USB 2.0 ports, connection speeds will be limited by the older interface's maximum throughput. USB 3.0 provides the necessary bandwidth to support full Gigabit Ethernet speeds up to 1000 Mbps.
Does this adapter work with both Windows and macOS computers?
This USB Ethernet adapter is designed to work with computers running various operating systems. Most modern Windows and macOS versions include built-in drivers that recognize the adapter automatically. For specialized or older operating systems, you may need to download specific drivers from Dell's support website to ensure proper functionality.
What is the maximum cable length supported by this adapter?
The adapter supports standard twisted pair Ethernet cables up to 100 meters (approximately 328 feet) in length, which is the maximum distance specified for 10/100/1000Base-T networks. For optimal performance, use Category 5e or higher quality cables that meet industry standards for Gigabit Ethernet transmission.
Can I use this adapter to add Ethernet to a computer that already has a working network port?
Yes, this adapter can add a second Ethernet port to computers with existing functional network interfaces. This is useful for creating separate network connections, implementing network bridging, or connecting to multiple networks simultaneously. The operating system will recognize both network interfaces independently.
What is the difference between this USB adapter and an internal PCIe network card?
This USB adapter provides external connectivity without requiring internal installation, making it ideal for systems without available expansion slots or for users who prefer not to open their computer cases. While internal PCIe cards may offer slightly lower latency in some scenarios, this USB 3.0 adapter delivers comparable Gigabit speeds with greater installation flexibility.
Does the adapter support Power over Ethernet (PoE) functionality?
No, this is a standard Gigabit Ethernet adapter that does not provide Power over Ethernet capabilities. It is designed solely for data transmission over twisted pair cables. If you require PoE to power connected devices such as IP phones or wireless access points, you would need a separate PoE injector or switch that provides both data and power over the Ethernet connection.
