I installed Ubuntu 12.04 on a NTFS partition on my Windows 7 machine. After installation Ubuntu will not connect to a network either Wired or Wireless. Windows 7 Networks work fine.

Ubuntu recognizes Wireless networks, prompt for authorization, yet cannot connect.

ifconfig shows local loopback (lo) and ethernet (wlan0) with no errors, no dropped packets, no overruns.

Any suggestions?

sudo lshw -C network output please? – Mitch Jul 17 '12 at 16:42

First, go to Additional Drivers and install all drivers. Your Wi-Fi network works fine as far as I can tell. Try to connect to Wi-Fi network using:

iwconfig wlan0 essid <Networkname>
dhcpcd -d -t 10 wlan0

Or maybe your local network is off. Try

ifconfig eth0 up
