No Gigabyte Ethernet on B520

Symptoms

I have a new B520 connected to a port on a  Netgear Gigabyte 8 port switch. The switch is connected at 100MB to a DLink router which is connected to a DSL modem. The Netgear switch also connects to two other Win systems that connect at 1GB, and an Snap server connected at 100MB.

 

The B520 says its link partner cannot connect at 1GB. It is using the gateway IP as the link partner which is the DLink 100MB router.

 

Both of the other PCs connect to the same switch and then router and I have a laptop that connects to the switch via a GB hub. None of the other systems have a problem.

 

How do I make the B520 ignore the router and  use any other system at 1GB so that it talks to the other PCs at 1GB and only slows for internet connections?

 

Diagnosis

The cables may not be properly aligned or installed, or some may be defective and need replacement.

Solution

The first thing to check when your system is not running at Gigabit speeds is the cable. You must have all 4 pairs (8 wires) working correctly for Gigabit. There are plenty of Ethernet cables around which only have 2 pairs (4 wires).

 

Check that they are all properly installed in the distribution box, and replace defective cables, if any.
