Description Wade Mealing 2007-04-05 17:07:19 UTC
Description of problem:

Networkmanager starts, wireless card comes up, selecting a network from the list
(Or when network manager auto-detects my home network, then autoconnects),
NetworkManager will fail to continue the connection.

Version-Release number of selected component (if applicable):


How reproducible:

1/3 times, but usually when I'm already frustrated after a long days work.

Steps to Reproduce:
1. Boot laptop, log into gnome.
2. See nm-applet do spinny thing
3. tail the var log messages, notice it didnt get a dhcp lease, frown.
Actual results:

nm-applet does not connect to my wireless 

Expected results:

nm to connect to my wireless server so I can go about my life.

Additional info:

It seems whenever it fails, I see the log in the messages..

Apr  6 02:43:36  localhost NetworkManager: <info>  Old device 'ath0' activating,
won't change. 

However when it works, I get

Apr  6 02:45:54  localhost kernel: ADDRCONF(NETDEV_CHANGE): ath0: link becomes ready

var log messages sections to be attached.

Comment 4 Doncho Gunchev 2007-05-03 19:53:49 UTC
This happens for me about 1/20 times, but gets better, mostly when the signal is
weaker. Does it help if you stop NM; rmmod (your_wls_card_module_here); insmod
(your...) and then restart NM? That works for me...

btw: I used only wpa_supplicant (edit the conf file and start) the first time I
got connected to my AP and it never failed. Maybe NM is not waiting enough at
some point and should certainly not clear my passphrase every time - ask yes,
but fill in the old one. I use the knetworkmanager applet and wpa2 if that matters.

Comment 5 Wade Mealing 2007-06-12 15:10:44 UTC
It usually does, but i cant get it to work properly.

This seems to work though.


service NetworkManger stop
/usr/sbin/wpa_supplicant -dd -Dmadwifi -c/etc/wpa_supplicant/wpa_supplicant.conf
/sbin/dhclient ath0

wpa_supplicant is of course populated with the correct values.

Comment 6 Wade Mealing 2007-10-25 15:53:41 UTC
Still happening in F8T3 and current rawhide.

And.. it still happens

Updated error messages.. this still works if i set it up manually.

Comment 8 Wade Mealing 2007-10-25 16:42:05 UTC

set /etc/sysconfig/wpa_supplicant up to look like this
INTERFACES="-i wlan0 "
DRIVERS="-D madwifi -dd"

Start the service, have it start on boot.. make this your wpa_supplicant startup
params, now it works.  Till we meet again networkmanager

Comment 9 Tim Lauridsen 2007-10-26 09:12:38 UTC
I have the same problems in current rawhide, NetworkManager can't connect to my
WPA AP at home.
I works if i use

service NetworkManger stop
/usr/sbin/wpa_supplicant -dd -Dmadwifi -c/etc/wpa_supplicant/wpa_supplicant.conf
-iath0 -B
/sbin/dhclient ath0

I will try modifying /etc/sysconfig/wpa_supplicant when i get home.
why wlan0, shouldn't it be ??
INTERFACES="-i ath0 "

Comment 10 Tim Lauridsen 2007-10-31 08:45:08 UTC
Thanks !!!!.

All my problems with NetworkManager & wpa_supplicant is solved in Rawhide.
NetworkManager connects without any problems to my WPA2 access point on my
Thinkpad T60 (Madwifi driver)

The is a problem connecting after suspend/resume, i have to 
modprobe -r ath_pci
modprobe ath_pci

Then it is working again. (I don't think this issue have any thing todo with NM)
