Problem with network in Ubuntu Intrepid Ibex [Solved]

Few days ago, I installed the newest version of Xubuntu called Intrepid Ibex. This version fixes some things and also includes some updates for applications I'm used to use. For instance Gimp 2.6 or Network manager and here the problem comes. The old version of Network manager, which I used in Xubuntu 8.04, worked just fine for me.
I work on my notebook so sometimes I switch between the cable and wifi connection, the old Network manager handled this fine but the new version doesn't. What's worse, the network didn't work at all in Intrepid Ibex for me. Sometimes I was lucky and I connected via wifi, but the connection was very unpredictable at all.
So I went through some Ubuntu forums hoping I would find a solution. And fortunatelly I found. The solution is a program called wicd.
Here is what I had to do, step by step:

1)

sudo

2)

echo "deb http://apt.wicd.net intrepid extras" >> /etc/apt/sources.list

3)

wget -q http://apt.wicd.net/wicd.gpg -O- | sudo apt-key add -

4)

apt-get update

5)

apt-get remove network-manager

6) Now because I definitely cut myself from the internet by uninstalling the network manager I had to download manually (from another computer) .deb package of wicd from here. Download a free network manager wicd.deb from SourceForge.net.

7) When you get the .deb file on your Ubuntu Linux, you just double click on the file, and it will start installation. And that's all, since this moment, my network works again. =)
