Did anyone get to the bottom of this? 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.
