Wireless problem with Thinkpad X220


I've been trying to help a friend out with wireless on his Thinkpad
X220. The identifier is:

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

Now, according to http://wiki.debian.org/rtl819x the drivers should
work for the kernel (2.6.39 bpo.2). However, while wlan0 is displayed,
he is unable to configure his network, and dmesg output says this:

[ 2343.267260] rtlwifi: wireless switch is off           

In spite of having switched the WiFi on, Network Manager doesn't see anything.

iwlist scanning gives:
Failed to read scan data : Network is down

Also, rfkill showed:
2: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no

An rfkill unblock removed the soft block, but that still did nothing.

I've run out of debugging ideas, and am looking for suggestions. Could
you let me know how I should go about this?


Sigh.  I like to think it's just the Linux people who want to be on
the "leading edge" so bad they walk right off the precipice.
