Today I installed Ubuntu 12.04 on my laptop. I am unable to see my home SSID or even connect to it.

I've tried to connect as a hidden SSID but I always get prompted for authorization although my key is correct.

I'm in in Europe but my laptop is from the US. I'm not sure if that is relevant. I've read around this site and saw something that has to do with setting the channel above 11.

I'm not sure I did that correctly I did this :

How to use Wi-Fi channels above 11?

Didn't help. I'm able to connect with cable but not via wifi either windows or linux. Other devices in my home can connect without any issues, even the kindle.

Here is the screenshot from my router :

Not sure about setting channel above 11? I do run all my devices on channel 6 (no matter if bought in Europe or USA), However your WI-FI channel is set on Auto and that should not be an issue.

Did you check if your WI-FI is hard blocked in BIOS? Got similar situation installing Mint in Europe on a Lenovo notepad bought in USA. And after endless CLI commands and installing newer drivers I was still only able to use cable to connect. Try this:

On first boot screen enter BIOS hit (F2 or F10 or F12 - depending on your BIOS configuration)

When in BIOS search for wireless to enable it if disabled (Most likely chose configuration -> wireless -> enabled)

When enabled confirm and boot normally (probably F10)

Hope it solves your problem.
