Actions to take if the link is unstable at 1000 Mbps
Depending on the type of connected hub, the link might not be stable at 1000 Mbps. If you want to use the
network at 1000 Mbps, verify the connection with the hub in advance. If the link is unstable at 1000 Mbps, you
can stabilize it as follows:
• Use a cable that is 20 to 100 meters long (UTP Category 5e or better).
• Set the master/slave mode setting to Master (valid only in the 1000 Mbps settings).
Perform the following procedure to set the mater/slave mode to Master. The link might not function depending
on the type of the hub. In this case, change the setting to Auto Detect.
1. Perform steps 1 through 5 in Setting the network transfer speed under 2.8 Setting Up the LAN Interface.
2. Click the Advanced tab. In the Settings list, select Gigabit Master Slave Mode.
3. From the Value drop-down list, select Force Master Mode.
