Ubuntu 10.04 networking stopped after running updates

I had problems with Ubuntu 10.04 after running updates, After a lot of playing about and hunting around on the net I found the best way of fixing this is as follows:

click on applications, a accessories, then select terminal

now type sudo apt-get remove network-manager

now type
sudo gedit /etc/network/interfaces

you will now be able to edit the file

add the following 4 lines

auto eth0
iface eth0 inet dhcp
auto wlan0
iface wlan0 inet dhcp

now save the file and reboot your system.
You will now find your wireless and lan works
