Hi,

Every few days I've started to get my notebook's network connection
giving out. This is what the log tells me:

 [Sat Jun 27 17:14:38 2015] wlan0: deauthenticated from
00:xx:xx:xx:xx:xx (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
 [Sat Jun 27 17:14:38 2015] cfg80211: Calling CRDA to update world
regulatory domain
 [Sat Jun 27 17:14:38 2015] wlan0: authenticate with 00:xx:xx:xx:xx:xx
 [Sat Jun 27 17:14:38 2015] wlan0: send auth to 00:xx:xx:xx:xx:xx

 [Sat Jun 27 17:14:38 2015] cfg80211:   (start_freq - end_freq @
bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time)
 [Sat Jun 27 17:14:38 2015] cfg80211:   (2402000 KHz - 2472000 KHz @
40000 KHz), (300 mBi, 2000 mBm), (N/A)
 [Sat Jun 27 17:14:38 2015] cfg80211:   (2457000 KHz - … etc.

Restarting network-manager often fixes it, but not always.

This is on Ubuntu 15.04, x86_64. Network card is Intel Centrino
Advanced-N 6235, which may well be part of the problem.

I realize that there's more info I should add, but short of dumping all
of /etc on you, I don't know what else would be useful.

cheers,
 Stewart
