We don't have N9 to reproduce. Please do the following: Add this line in /etc/rsyslog.conf: kern.* /var/log/kernel Restart rsyslog: # systemctl restart rsyslog.service Reload module with verbose debug option to grab messages: # modprobe -r iwldvm # echo > /var/log/kernel # modprobe iwlwifi debug=0x47ffffff Reproduce the problem. Unload module # modprobe -r iwldvm Then please provide /var/log/kernel file. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.11.1-200.fc19. Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those. It seems that you are connecting to an IBSS on a channel that is not allowed because of regulatory issues. Can you please choose a different channel (1 to 11 prefereably) and report back? Thanks Hi, I wasn't able to reproduce the problem recently. I've tried debug setup proposed in comment #1. Either various kernel and firmware updates fixed my problem, either the environment changed so that I'm not facing the issue. For the record, I'm in France and the Nokia N9 hotspot utility propose only channels 6, 11 or automatic. Regards. Closing per above comment. |
Created attachment 762068 [details] an extract of dmesg Hi, I'm getting stuck many times not being able to use the hotspot provided by my smartphone (Nokia N9). Many errors are reported by the firmware and the kernel. This is not a regression, since the connection was already unreliable in Fedora 17. But it became unusable in Fedora 19. Some of the error messages: iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Advanced-N 6205 AGN, REV=0xB0 iwlwifi 0000:03:00.0: Microcode SW error detected.
