The recent xubuntu 14.04 release has made it much easier to install new
kernels on ageing Pentium Ms, which say they don't support PAE but in
fact do so without problem.  An additional boot parameter (forcepae)
gets one going.  I discovered that it was in principle possible to do
this on 12.10 to 13.10 using an application add-in, but it was a little
more complex to do so.  The better support in 14.04 makes it all much
easier.

So I have now moved on to the latest kernel (and 14.04).  After several
days I've had no problems, so I've changed the status of this bug to
'fixed released'.

** Changed in: linux (Ubuntu)
       Status: Incomplete => Fix Released

Title:
  WiFi sometimes connects, sometimes doesn't, sometimes stops, Kernel
  bug

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  I am using an old Sony TR1MP 32bit laptop, ubuntu 12.04 (the system is
  not supported by later ubuntu versions).

  I use a Micronet wireless USB dongle since the inbuilt wifi is very
  slow, and is disabled by blacklisting it.  The dongle shows if it is
  working since it flashes blue when it does.

  Lately the wifi connection often fails at boot, with the system not
  attempting to connect (the dongles does not light up).  Sometimes it
  works, and then drops out later.  Sometimes it reconnects by itself,
  sometimes not.  Sometimes removing the dongle, waiting and then
  reinserting it works, sometimes not.

  Looking at syslog, I see the attached Kernel errors when the
  connection fails.  The problem seems to have got worse recently.  The
  wifi has always been a little unstable, but is now nearly unusable.

  I will gladly supply more information if someone can tell me precisely what is needed.  I'm not an expert at linux, but not totally useless at it either.
