I have no wired or wireless connectivity in Ubuntu or Linux mint. I have tried Gnome and KDE versions of both. Networking works in Windows 7 on the same machine. In the Ubuntu 12.10 Network manager (in the control panel), I only have two items listed on the left: "Wired" and "Network Proxy".

"Wired" only says "Cable Unplugged" and my MAC address. The options button is not clickable.

The only interface I could add in this menu is VPN.

This is my output of ifconfig -a

ubuntu@ubuntu:~$ ifconfig -a

What exact model of wired and wireless adapters do you have? If you don't know, what model of computer? Are you trying to connect to wired or wireless? – Gilles Feb 3 at 19:17
