Comment 1 Stanislaw Gruszka 2011-04-22 12:15:41 UTC 
Does swcrypto=1 (or swcrypto50=1) module option helps?
Comment 2 lionghostshop 2011-04-22 12:22:03 UTC 
hwo to use swcrypto=1 (or swcrypto50=1) module option?
Comment 3 Stanislaw Gruszka 2011-04-22 12:43:03 UTC 
Like described here:
https://bugzilla.redhat.com/show_bug.cgi?id=688252#c6
but use "options iwlagn swcrypto=1 swcrypto50=1" .
Comment 4 lionghostshop 2011-04-23 17:16:43 UTC 
it works well again after some software updates. Thanks
Comment 5 Stanislaw Gruszka 2011-04-26 06:03:19 UTC 
I'm confused. Did you update NetworkManager or wpa_supplicant, and things start to works?
Comment 6 lionghostshop 2011-04-26 07:47:05 UTC 
I am not really sure since many packages were updated via yum, including packages like sssd, etc.
Comment 7 Stanislaw Gruszka 2011-04-26 09:13:16 UTC 
Ok, let's close bug.
Comment 8 lionghostshop 2011-04-30 00:28:18 UTC 
The problem occurred again, I tried following,
I still need 3-4 times to establish a connection.

echo "options iwlagn swcrypto=1 swcrypto50=1" >> /etc/modprobe.d/iwlwifi.conf

rmmod iwlagn
rmmod iwlcore
modprobe iwlag
Comment 9 Stanislaw Gruszka 2011-08-15 19:29:45 UTC 
How things looks now on 2.6.40 kernel?
Comment 10 lionghostshop 2011-08-16 00:51:36 UTC 
I must remove swcrypto50=1 in order to connect to wifi now.
Comment 11 Stanislaw Gruszka 2011-08-17 19:35:46 UTC 
Yeah, I saw your other bug report :-) But does the problem described comment 0 and 8 still occurs?
Comment 12 lionghostshop 2011-08-19 06:27:17 UTC 
It works well now.
Comment 13 Stanislaw Gruszka 2011-08-19 22:26:05 UTC 
I hope this time issue is gone for sure.
