First off, I'm new to Linux - I have Windows 7 installed in my laptop. I thought of installing Ubuntu 12.04 and I used the option "install alongside windows". So every thing went down good except Network Manager icon did not show the wireless connection that I get in Win 7. I have gone through almost all forums. I followed some instruction (terminal commands) but i just came to know that those command require internet connection. So, its no benefit. And just recently i removed network manager using the code
sudo apt-get remove --purge network-manager-gnome network-manager
for some stupid reasons (don't ask) and now i can't re-install using the code
sudo apt-get install -d --reinstall network-manager network-manager-gnome
I guess that code also needs internet connection. I am FRUSTATED out of my mind. Need help badly.
