We probably need to see the output from running 'dmesg' shortly after a reboot. Created attachment 776194 [details]
dmesg
OK, there is output of this command. It is from actual liveCD with gnome, directly after boot of OS.
There is no messages about iwlwifi, that module is not loaded. Either it is blacklisted or udev does not load it automatically. What happen if you do "modprobe iwlwifi" . Created attachment 776892 [details] dmesg after modprobe iwlwifi so I did it. modprobe iwlwifi has no output, but wifi still don't work. In attachement is added new dmesg output after this command, just for sure. I just did some google research for this problem and I find out, that on Ubuntu was something, what seems very similar. There is some patch, but it is in .deb and I am not sure if it can be used on rpm based system, in some way. http://askubuntu.com/questions/295027/lenovo-t431s-and-and-wireless-dont-play-nicely I also tried (after modprobe command) grep some info from logs. pwd = /var/log grep -ir iwl - no output [root@localhost log]# grep -ir wifi messages:Jul 22 08:41:15 localhost NetworkManager[715]: <info> WiFi hardware radio set enabled messages:Jul 22 08:41:15 localhost NetworkManager[715]: <info> WiFi enabled by radio killswitch; enabled by state file messages:Jul 22 08:41:19 localhost NetworkManager[715]: <info> domain search 'wifi.nat.' messages:Jul 22 08:42:44 localhost kernel: [ 101.972836] Intel(R) Wireless WiFi driver for Linux, in-tree:d Binary file journal/7725dfc225d14958a625ddaaaea5962b/system.journal matches I looked into BIOS and it seems, that everything connected with wifi shoud be enabled. I also tried use fn + other keys, but with no effect. Just realized that this patch is missed on 3.9 and it most like fix this issue https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=20ecf9fd3bebc4147e2996c08a75d6f0229b90df It is already on 3.10. Josh please apply it on 3.9 kernels as fix for this bug. F19 is rebased to 3.10 now, just not built yet. I've applied the patch to F18. kernel-3.9.11-200.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/kernel-3.9.11-200.fc18 kernel-3.9.11-200.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report. |
