[Bug 1361290] [NEW] hard time with wifi connection after suspend/resume

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I have to say that since I upgraded to 14.10 I've been having tons of
problems with my wifi.  Some of them seemed to be related to network-
manager while in some other cases not...  I've noticed the following
entries in dmesg after suspend/resume which happend at the same time as
my wifi was having hard time to allow me viewing web pages or apt-get
commands being really really really slow.
