I had the same problem as mentioned above on my EEEpc 1005HA running the netbook remix of Lucid Beta 2 (I had no problems with Karmic):
i.e. rfkill list showed:
...
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
After reading through all of this, I checked the BIOS and found that wireless was disabled.
Enabling it fixed my problems, and rfkill now longer shows the phy0 as Hard blocked.
