Do I need to use a crossover cable or straight-through cable?
With most of D-Link's switches and routers, the Ethernet ports are Auto MDI/MDI-X. This means the port will auto-detect the
cable type. Auto MDI/MDI-X ports may react differently if the Ethernet cable is not properly pinned. If you make your own
cables, it is very important that they follow the industry standard pin-out (568A and 568B).
Computer connections to a switch or router typically use a straight-through cable. When connecting a computer to another
computer or to an uplink port then a cross-over cable is typically required. Rule of thumb: "If there is a link light, the cable is
right. "
Why isn't my DUB-E130 achieving 1 Gbps speeds?
1 Gbps (1,000 Mbps) is the theoretical maximum speed of the Gigabit Ethernet standard, and actual speeds may vary. Gigabit
connectivity is dependent on a number of factors, and just one weak link in your network can reduce data speeds. If you are
not achieving Gigabit speeds, you should check the following:
• Ensure that the DUB-E130 is plugged in to a USB 3.0 port, and that the drivers for this port are correctly installed.
• Check your network cable. A cable of specification CAT 5e or above is required for Gigabit speeds, with a maximum
length of 100 metres. Also check the cable for damage, or wear and tear.
• If you are connected to a switch or router, ensure that this device is also Gigabit-capable.
• Network congestion can also affect data rates. Slower speeds may be due to heavy data traffic elsewhere on the network.
