===== Network Setting/Speed Check =====

//Superuser (su or sudo) credentials required//

The //ethtool// linux tool can be used to check network settings. Using the command:

<code> ethtool "connection" </code>

where, "connection" implies your network access point such as em1, eth0, eth1, etc.. This command will display information based on the network point you enter, such as speed, duplex, available connections, etc..

//Ethtool// can be used to set network properties as well. For example, on network access point "em1", to set the speed to 1000 mbits, duplex to full, and auto-negotiation to off:

<code> ethtool -s em1 speed 1000 duplex full autoneg off </code>

For more information on how to use ethtool and other setting options, type in //ethtool -h// in the terminal.

**Please make sure you disconnect from the network and connect again after any changes have been made, as sometimes they will not take affected until the network connection is reset or turned off and restored**

===== Incorrect Speed Checklist =====
If the network is not gigabit:

  * Make sure you network interface card (NIC) can support gigabit speeds
  * Make sure your cable can support gigabit speeds
  * Test computer at different network port. Gigabit network speeds may not have been enabled in all locations
