I am using Ubuntu 12.04. I deleted network manager and do not see both wireless and LAN connection icons in the desktop, and for this reason I cannot connect to the internet. Any idea?

Please open a terminal and do:
gksudo gedit /etc/network/interfaces
Amend the file to:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Proofread, save and close gedit. Now do:
sudo ifdown eth0 && sudo ifup -v eth0
Your ethernet should now be connected so that you can re-install NM or Wicd. After doing so, repeat the process but remove the eth0 lines if you select NM. I believe the eth0 lines may remain for Wicd.
If you delete Network Manager you have to configure all network settings manual. This is a bunch of work. However, it's possible.
Why do you have removed it? It is very convenient and I think you could configure all thinks you need.
A good advice for the manual network configuration you can find here: Network Configuration
Whenever I delete network manager I can put an UTP cable in my system directly into my router. A reboot (or a /etc/init.d/networking restart) resets the networking and also shows me my LAN connection (though not with icons on the desktop it does work).
After that you can re-install network-manager (or wicd as that was the one I started using for a little while) over the wired connection.
/etc/init.d/networking restartthrough errors?
