Fix slow wireless internet problem on Ubuntu, Linux Mint etc.

Since first day that I update my Ubuntu 10.10 to 11.04, I noticed my WiFi is very horrible. I can connect any network. But it's very slow. I can't browse any website or if I can - it just takes 30+ seconds. But my WiFi works normal on Windows. Tried bunch of methods from internet and nothing fixed this issue.

I'm using an Acer Aspire 5720G and iwl4965 network card.

After challenging this issue for days and hours, managed to how to fix it.

Solution is replacing default "network-manager" with "wicd". After doing this, my connection was full speed again!

This method also works with all LinuxMint and Ubuntu variants just like Kubuntu, elementary OS and all other Ubuntu based distros.

How to fix it? 

  1. Open Terminal and type commands below.
  2. sudo apt-get install wicd
  3. sudo apt-get remove network-manager-gnome network-manager
  4. Open wicd from programs menu and connect your network.
  5. Enjoy full speed internet again on your Ubuntu! 


  1. Please don't follow this it breaks everything in Linux Mint 17

  2. Dont do it! Mint 17 is down after these changes! Had to reinstall drivers and cinnamon desktop to fix

  3. Thank you so much. It really worked for me. I checked the change in my internet speed by having a speed test from :)

  4. Thank you, it worked on an acer-aspire one netbook running Debian Stretch and Xfce4.
