So...I may have made a huge mistake. I can't get my wifi working on my work Lonovo T410 after formatting the drive with windows 7 on it. I think the wifi may have been shut off when I obliterated the old install...

Here's what I know, when I run lshw -C network, I get this output:

*-network DISABLED
   description: Wireless interface
   product: Centrino Advanced-N 6200
   vendor: Intel Corporation
   physical id: 0
   bus info: pci@0000:03:00.0
   logical name: wlan0
   version: 35
   serial: 00:27:10:d7:b1:a0
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
   configuration: broadcast=yes driver=iwlwifi driverversion=3.11.0-15-generic firmware=9.221.4.1 build 25532 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn
   resources: irq:43 memory:f2400000-f2401fff

So it looks like there is a driver there, and it is installed correctly. Though if anyone has guidance beyond Ubuntus own troubleshooting guide, I'd love to hear it.

I got this laptop to take to a programming conference this weekend, and wanted to quickly get Ubuntu up and running so that I could be productive when I got there. In my rush I formatted the drive and threw Ubuntu 12.04 onto the laptop.

Small problem, the Windows 7 install was a fully configured install (they're just going to flash the laptop when I give it back, so no worries there.) I think they had the wifi turned off for security purposes... So now I can't turn the wifi on, no matter what I do.

The end of Ubuntu's official documentation says to just go to the old OS and turn the wifi on, but I don't have that option anymore (out of time...). Does anyone know how to just force the wifi back on?

    'Disabled' usually refers to the wireless switch. What does this tell us? rfkill list all What is the position of the wireless switch on the right hand side?
