"deconfiguring network interfaces" kills wireless on NetMan?



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:
awhite 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:
awhite author:~$ sudo service NetworkManager stop
NetworkManager: unrecognized service

So I thought I'd try this also:

awhite author:~$ sudo service NetworkManager restart
NetworkManager: unrecognized service


    sudo service network restart

MY RESULT:
awhite 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:

ADDITIONALLY:
