Description Kent Kristensen 2011-05-13 13:11:44 UTC
Description of problem:
I am unable to  switch on the wireless network on network manager. I have tested both Fedora 15 beta and Fedora 15 nightly build

I am currently using a laptop with ath9k. I am uncertain whether there is a missing kernel module, or if there is some error in the NetworkManager application. The problem exists both in the normal desktop edition and the kde spin 

Version-Release number of selected component (if applicable): 15 beta, 15 nightly build. (didnt check the NetworkManager version)


How reproducible:
Every time.

Steps to Reproduce:
1. Click on NetworkManager
2. Trying to change wireless state from Off to On
  
Actual results:
The NetworkManager does not switch and remain turned off

Expected results:
Activating the wireless network and get a list of available networks

Additional info:

It could be an issue with ath9k driver or with a platform driver blocking the WiFi.

Please could you report the following pieces of information:
1. your laptop type
2. lspci -vv | grep -B 12 ath9k
3. rfkill list
4. rpm -q kernel
5. nm-tool

Comment 2 Kent Kristensen 2011-05-24 19:54:23 UTC
Sorry for the late reply. 

It seems to be related to the networkmanager or some configuration I havent used previous. Anyway; here is the the answer/output:

1. your laptop type

Comment 3 Jirka Klimes 2011-05-25 12:34:06 UTC
The problem is platform driver 'acer-wireless' which blocks the wireless. Either it doesn't behave or you should activate the wireless pressing a key-combination.

Removing the driver should help:
# rmmod acer-wmi

See also bug 658003.

Comment 4 Kent Kristensen 2011-05-25 14:20:03 UTC
The ath9k works fine with my gentoo and win7 partition. It also worked fine in Fedora 14. 

#rmmod acer-wmi

worked! Thanks! 

as temp solution I blacklisted the acer-wmi (/etc/modprobe.d/blacklist.conf)

The problem seems to be fixed :)
