Speed up Ubuntu Linux Ethernet connections

Rightardia uses BrightHouse Lightening at home but noticed that the Internet speeds seemed to be about half of what it should be.

We also noticed that the Ethernet connections dropped several times a day which was annoying. Our technical editor, Wirehead, decided to set up a static connection rather than use the Automatic Dynamic Host Configuration Protocol (DHCP).

If your Ubuntu System has set to use DHCP, you will want to change it to a static IP address.

There is a way to use Ubuntu's GUI to make the change to a static IP address. Start by adding a new Wired connection.You may have to check the connection information in the Network applet if you have more than one Ethernet card to see which one is active.

Here we can se that the active DHCP connection is eth1.

Next disable the DHCP connection by unchecking 'connect automatically. Cut the MAC address form the active connection and paste it into the new static connection.

Here is where you paste the MAC address into the new static connection.

You now need to configure the new static connection with a IPv4 address, a subnet mask, a gateway, a DNS server address and a search domain. In general, the gateway, the DNS server address and the search address is the IP address of the cable modem router or gateway. You may wish to ping a candidate IP address to make sure another PC in your network is not using it.

Once our technical editor, Wirehead, changed the Ethernet connection to a Static IP address, he noticed a amazing increase in speed when he was browsing the Internet. Bandwidth speed test results were excellent and the connection drops stopped.

This could be a problem with the DHCP server on the Bright House wireless gateway. In any event the entire Rightardia network now uses a static IP addressing scheme.
