<p class="MsoNormal">Hi,<br>
<br>
Every few days I've started to get my notebook's network connection<br>
giving out. This is what the log tells me:<br>
<br>
[Sat Jun 27 17:14:38 2015] wlan0: deauthenticated from<br>

<br>
Restarting network-manager often fixes it, but not always.<br>
<br>
This is on Ubuntu 15.04, x86_64. Network card is Intel Centrino<br>
Advanced-N 6235, which may well be part of the problem.<br>
<br>
I realize that there's more info I should add, but short of dumping all<br>
of /etc on you, I don't know what else would be useful.<br>
<br>
cheers,<br>
