move the same load into a different port on the same

 

hub. If it works, there is probably a faulty port or bad

 

RJ45 port connection. If possible, try to connect the

 

load device into a different hub.

 

Try using a different Ethernet cable. If it works, there

 

is probably a faulty connection over the long cable,

 

or a bad RJ45 connection.
