reinstall network manager without Internet

[davidsanchezvasquez]

I have been trying to do this without success

Today I was trying to configure a wireless network for my pc and it ended in a mess and now I dont see anywhere the wifi icon (yes, I have already tried "add notifications")

The thing is that it seems the whole network manager is not longer there

I have downloaded the package to reinstall it (Im writing now from a friend's pc) without sucess, because network manager needs other packages who are supossed to be downloaded from the internet while the installation, but I do not have Internet!

So what can I do?

Any help will be appreciated

Basically you have two options. Strictly speaking you don't absolutely need NetworkManager for an internet connection, so you can configure your connection manually on the command line (can be a pain if you need to connect to a WPA-protected wifi network, not difficult at all for wired connections).

For a wired connection most likely all you need to do is connect the cable and run this in a terminal:

sudo dhclient eth0Of course that's assuming your ethernet interface is eth0 (could be eth1 if you have 2 NICs).

Or since you're able to post here I imagine you have another machine with internet access or at least a LiveCD. From that environment you can download the .debs you need from packages.ubuntu.com. Here's the ones related to network-manager I have on mine:

network-manager
network-manager-gnome
network-manager-openvpn
network-manager-pptp
network-manager-vpnc
I think the last ones can be left out depending on your particular VPN connection needs.

thank you, the problem is solved :D

I re-installed the following packages in that order:

1) modemmanager
2) network-manager
3) network-manager-genome

Then re-started the system and I have my Wifi icon back and thus Internet again :)

Cheers!
