Reset network settings to default

Asked by Jon Charge

How do I reset all my network settings back to the default when karmic installed. The network manager icon won't recognise the connection, and I can not manage it that way. I messed with my settings and created this condition, and I would like to undo everything back to the original settings. I'm not sure how.

If you just modified the settings using the NetworkManager, try the following:

1. You have to get the network-manager package for karmic from the internet, use another computer and a USB thumb drive if you currently have no internet connection.

2. Download the package from a mirror: http://packages.ubuntu.com/karmic/i386/network-manager/download (i386) or http://packages.ubuntu.com/karmic/amd64/network-manager/download (amd64) and place it on your karmic machine

3. Move the current NetworkManager settings away: sudo mv /etc/NetworkManger /etc/NetworkManager_old

4. Reinstall the previously downloaded package by running sudo dpkg -i FILE, for example: sudo dpkg -i network-manager_0.8~a~git.20091005t192303.1d28ad1-0ubuntu2_i386.deb

5. Start the NetworkManager and verify your settings. This should create a new settings file inside /etc/NetworkManager

Can you help with this problem?
