Internet connection is very slow on Karmic Koala-Solution-

November 16, 2010 by: upa_kid

One of the big bugs (https://bugs.launchpad.net/ubuntu/+bug/433972) on Ubuntu 9.10 Karmic koala is the slow internet connection, i have a connection of 25Mo/s and even that it take too long to load a page, at the begining i tought that was something wrong with my router or with my wireless card untill i discovered that is a known bug in karmic koala and there are many people fronting th same problem as me. I found a solution somewhere, and has worked for me for the moment. Please try it and report if worked for you also.

1. Right-click on ‘Network Icon’ (located at top-right panel by default) and click on ‘Edit Connections’ to open Network Connections Manager.

Network Manager :

2. Choose the type of connection you have. For this example, in my case “Wireless”, select the connexion (My case Auto unixmen) and click Edit

3- Inside editing ” auto unixmen wireless” click on ‘IPv4 Settings’ tab.

4. Under ‘IPv4 Settings’, change the ‘Method’ to Automatic (DHCP) addresses only.

6. Put these nameserver addresses as your ‘DNS Servers’: 208.67.222.222, 208.67.220.220

7. Click ‘OK’ and reboot your machine. You can then visit http://welcome.opendns.com to confirm you are using OpenDNS. (Need registration)

8. NOTE:

To avoid having your settings get revoked after reboots, or after periods of inactivity you may need to make the following changes via the command line:

$ sudo cp /etc/resolv.conf /etc/resolv.conf.auto
$ gksudo gedit /etc/dhcp3/dhclient.conf
# append the following line to the document
prepend domain-name-servers 208.67.222.222,208.67.220.220;
# save and exit
$ sudo ifdown eth0 && sudo ifup eth0

You may be required to change eth0 to your own network device’s name if it uses a non-standard name.
