Intel Centrino N-1000 WIFI problems on Linux Ubuntu

I have a laptop with the Intel Centrino N-1000 wireless card running Ubuntu 12.10.

The Ethernet card works fine, but the wireless card doesn't.

When I click the Networking icon I see that wireless is disabled by hardware switch.

Screenshot:

I checked the switch on my laptop and it is ON!a

I tried:

-Restarting the Computer

-Copying the ucode firmware file to /lib/firmware

-sudo iwconfig wlan0 power off && sudo iwconfig wlan0 power on

-Going to Settings>Software Sources>Additional Drivers but "No propertiary drivers are in use"

Still the same problem. EDIT: After typing sudo rfkill list I discovered the wireless card was soft-blocked and hard-blocked.

I typed sudo rfkill unblock wifi.

Now the card is still hard blocked.

user@linux-laptop:~$ sudo rfkill list 
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
2: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
3: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no

While searching for a solution I found some people having similar problems.
Reseting the BIOS to defaults helped me and them.
I don't know how this worked, but it looks like magic.

I had a similar problem with a Lenovo T410 laptop. I solved my problem with help from this page, which suggests using an older driver.

Hi, can you quote the relevant parts from that link in your answer? – bertieb – 2017-03-20T00:14:32.203

OK. Here's what he says: – vsh – 2017-03-21T14:22:36.797

aaargh -- if I could figure out how to format these comments I would cut-and-paste a section of the referenced page. :-( But, IMO, the description in the link is pretty thorough, and better than a summary. – vsh – 2017-03-21T14:35:31.313

The summary should be edited into your answer. Quoting parts is fine, but including a description in your own words is better. The reason for including it here is if the link disappears or changes or similar- if you include the information here your answer will still be useful regardless :)
