How can I re-install NetworkManager fromCD?

[bliffle]

I installed 10.10 and ran it for a few weeks and then (foolishly) installed Wicd and tried it and it failed. So I had no network connection. Can I re-install NetworkManager from the 10.10 CD? Or is there something else I can try in order to restore wifi access?

In synaptic>repositories>check CD-ROM as repository and reload.Now you should be able to install from CD.Put CD in drive and try to install network-manager.BTW it is strange that wicd doesn't work.
