I want to let other devices connect via WiFi to my new ThinkPad X220 (tablet). I'm running Kubuntu 12.04. How do I determine if my X220 will function as a WiFi HotSpot?

Here is the info hwinfo returned:

UPDATE: this forum post indicates the X220 can act as a WiFi HotSpot. If that is correct, then I have to figure out why Kubuntu won't facilitate this...

iwlwifi is a proprietary driver. choosing opensource driver like madwifi would allow ubuntu to configure the card as access point.

Create an ad-hoc connection. other devices will then connect to that access point.
