[Bug 1392999] Re: On Intel 3945ABG, Wi-Fi constantly stops functioning


Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

  On Intel 3945ABG, Wi-Fi constantly stops functioning

Status in “linux” package in Ubuntu:

Bug description:
  Essentially, sometimes my Wi-FI simply stops functioning without
  disconnecting from the network - I am unable to access any Internet
  pages and all my downloading files are stuck - this, obviously, is an
  undesired effect caused by a bug, as I wish to use Internet normally
  without any interference. The only workaround regarding the effect of
  this bug is reconnecting to the Wi-Fi network or restarting the
  computer - however, the bug usually appears in chain - this means that
  reconnecting or restarting usually will give me my Internet access
  only for a couple of seconds or minutes until I lose it again due to
  same issue.

  This bug appears frequently under normal workflow, but it is
  especially common whenever I attempt to download large (1GB+) files
  either via direct download or BitTorrent client. This bug is present
  in earlier versions of Ubuntu(13.10, 14.04) and actually did affect
  other distributions as well but it appears that it is much less severe
  in 14.10 - an Ubuntu version I currently report this bug from. Default
  14.10 kernel was not changed. I have made slight changes in /usr/lib
  /pm-utils/power.d/wireless(disabled Wi-Fi power savings) and
  /etc/pm/config.d/blacklist(blacklisted Wi-Fi power management) in
  order to lessen the outcome of this bug but I do not think that it
  have changed much and bug was present in the same form before I have
  made those changes.
