I finally gave in and updated xubuntu-11.04 to 11.10 on my Acer
Aspire One netbook. Since upgrading, I have been unable to use the
wireless adapter to connect to a network. It worked fine with
11.04, and it still works fine in Windows XP so I know it isn't a
hardware issue. The kernel module "ath5k" loads, but the Network
Manager cannot find a network to connect with.
lshw sees the hardware:
*-network
description: Wireless interface
product: AR242x / AR542x Wireless Network Adapter

vendor: Atheros Communications Inc.
physical id: 0

logical name: wlan0

I can invoke ifconfig to wake up the interface and assign it an
address:
wlan0 Link encap:Ethernet HWaddr 00:24:2c:1a:72:57

RX bytes:6554 (6.5 KB) TX bytes:18836 (18.8 KB)
But I still am not connected to my wireless network.
iwconfig shows the interface:

And iwlist finds the signal from my access point:

But rfkill shows a soft block I am unable to clear:

Is there a solution short of reverting to 11.04?
