It is my current belief that the message seen on shutdown (HP G60,
Ubuntu 10.10.1, Atheros 5K) that Network Manager is deconfiguring
network interfaces is part of the issue with wireless no longer working
with Network Manager. In any event, I'd like to be able to again use
this laptop with wireless! Soon! Thanks.
Is there a replacement for NetworkManager on Ubuntu that allows wireless
to work again? It works great under Windows Vista Home Premium on the
same laptop...

I'm no expert, but the 3 things I try when NM doesn't work
(not an infrequent occurrence):
1. Run "sudo iwlist scan".
If that sees something then the problem is certainly with the NM setup.
MY RESULT:
awh...@author:~$ sudo iwlist scan
[sudo] password for awhite:
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
wlan0 Interface doesn't support scanning : Network is down
wlan1 Interface doesn't support scanning : Network is down
2. Try the network service instead of NM;
sudo service NetworkManager stop
MY RESULT:
awh...@author:~$ sudo service NetworkManager stop
NetworkManager: unrecognized service
So I thought I'd try this also:
awh...@author:~$ sudo service NetworkManager restart
NetworkManager: unrecognized service
sudo service network restart
MY RESULT:
awh...@author:~$ sudo service network restart
network: unrecognized service
3. Check that the entry in /etc/sysconfig/network-scripts/ifcfg-wlan0
is reasonably accurate.
MY RESULT:
vi /etc/sysconfig/network-scripts/ifcfg-wlan0
"/etc/sysconfig/network-scripts/ifcfg-wlan0" [New DIRECTORY]
4. Check /var/log/messages (I pulled out a few but there are MANY messages)
MY RESULT:
