I installed F25 a couple of weeks ago and network performance is noticeably poorer on this machine. When browsing the internet, or particularly on Ajax based sites like gmail or google search connections seem to just drop. The previous Fedora that was on this machine (23 I think) was fine, and my laptop (still on an older Fedora) and other devices have not experienced any change. Looking in journalctl as root I see frequent renegotiation with the AP, e.g.: Mar 24 00:21:29 atlas wpa_supplicant[864]: wlp2s0: SME: Trying to authenticate with xx:xx:xx:xx:xx:xx (SSID='X' freq=5200 MHz) Mar 24 00:21:29 atlas kernel: wlp2s0: disconnect from AP xx:xx:xx:xx:xx:xx for new auth to 00:a4:23:17:18:e5 Mar 24 00:21:29 atlas kernel: wlp2s0: authenticate with xx:xx:xx:xx:xx:xx Mar 24 00:21:29 atlas kernel: wlp2s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) Mar 24 00:21:29 atlas kernel: wlp2s0: authenticated Mar 24 00:21:29 atlas kernel: wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3) Mar 24 00:21:29 atlas wpa_supplicant[864]: wlp2s0: Trying to associate with xx:xx:xx:xx:xx:xx (SSID='X' freq=5200 MHz) While the machine is supposedly connected. There's also this, Mar 24 00:21:29 atlas systemd-udevd[5658]: Process '/usr/sbin/crda' failed with exit code 249. which can't be a good sign. -- imalone http://ibmalone.blogspot.co.uk _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
