Anshul Ranjan, could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.17

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

  After that on reboot, my WiFi starts - works for 10-15 minutes and then the computer hangs for a few sec and then WiFi module stops blinking and cannot detect my network at all. Restarting Wifi hardware switch doesn't help either. I have to reboot the system and the problem repeats.
  My system has been working smoothly for many months so far.

  I looked at syslog and found following
