F14 RC3 WLAN not working; F13 works fine

[Ron Leach]

List, good morning,

On Acer AspireOne netbook, F14RC3 beta network manager does not see, 
or allow connection to, wireless networks that exist.  Network icon 
has a red cross against it.  Wireless networks do not show in the 
network popup.  Adding 'connections' via the popup still doesn't let 
NM 'see' the active WLANs.

F13 (Goddard), on the same netbook, sees the networks and connects to 
them without difficulty.

Machine: Acer AspireOne AOA150
WLAN: Atheros AR5001
F14: XFCE live CD, Sept 30 2010 release for CD
Updates: 'yum update' run 5 Oct 2010

Here an extract from lspci -v

This is quite odd, users won't be expecting things that worked on F13 
to stop working on F14, so I'd like to help sort out what the problem 
is.

Please let me know what information is needed to pin this down, or 
whether I should try some other commands.

regards, Ron
