Fedora 24 WiFi connection issue

asked 2017-05-11 06:43:08 -0600

I have laptop Lenovo T450s with installed Fedora 24. Sometimes when Im leaving my laptop alone it disconnects from WiFi and won't connect again. Command systemctl status NetworkManager gives output:

Restarting NetworkManager doesn't help. Only rebooting laptop do the job.

Try out journalctl -f -u NetworkManager | tee network.log That shows you what happen, when it disconnect. Can be that your wifi interface go to power sleep...

From that point I don't know, whats happen. But next time you got a log file ... before and when it's happen.

Might be helpful you try another kernel...

Checkout the firmware by intel

http://www.intel.de/content/www/de/de...

On my fedora 25 follow package is installed: iwl7260-firmware.noarch 1:25.30.13.0-72.fc25 @updates

how to know which exactly firmware I need to install? modinfo iwlwifi shows a lot of different versions. I'm a bit confused what I need to do...

I found some workaround: I just killed wpa_supplicant.conf process and restarted NetworkManager service.
