I am bit skeptical about installing a non-released version of kernel. Right now I do not want to spend time in fighting fires with possibly unexpected bugs and breaks - apologize for that. I will definitely try it out in few days and will update.
Thanks a lot again ! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1380276 Title: WiFi disconnects and unable to discover network until reboot after upgrading to linux 3.13.0.37 Status in “linux” package in Ubuntu: Incomplete Bug description: Yesterday (11 Oct, 2014 9:36 AM IST) my kubuntu was upgraded using muon package manager with following list of packages Start-Date: 2014-10-11 09:36:29 Install: linux-image-extra-3.13.0-37-generic:i386 (3.13.0-37.64, automatic), linux-headers-3.13.0-37:i386 (3.13.0-37.64, automatic), linux-headers-3.13.0-37-generic:i386 (3.13.0-37.64, automatic), linux-image-3.13.0-37-generic:i386 (3.13.0-37.64, automatic) Upgrade: apt:i386 (1.0.1ubuntu2.4.1, 1.0.1ubuntu2.5), linux-headers-generic-pae:i386 (3.13.0.36.43, 3.13.0.37.44), rsyslog:i386 (7.4.4-1ubuntu2.1, 7.4.4-1ubuntu2.3), libapt-pkg4.12:i386 (1.0.1ubuntu2.4.1, 1.0.1ubuntu2.5), bash:i386 (4.3-7ubuntu1.4, 4.3-7ubuntu1.5), linux-generic-pae:i386 (3.13.0.36.43, 3.13.0.37.44), linux-generic:i386 (3.13.0.36.43, 3.13.0.37.44), apt-utils:i386 (1.0.1ubuntu2.4.1, 1.0.1ubuntu2.5), libapt-inst1.5:i386 (1.0.1ubuntu2.4.1, 1.0.1ubuntu2.5), linux-libc-dev:i386 (3.13.0-36.63, 3.13.0-37.64), linux-image-generic:i386 (3.13.0.36.43, 3.13.0.37.44), linux-headers-generic:i386 (3.13.0.36.43, 3.13.0.37.44), google-chrome-stable:i386 (37.0.2062.120-1, 38.0.2125.101-1), apt-transport-https:i386 (1.0.1ubuntu2.4.1, 1.0.1ubuntu2.5) End-Date: 2014-10-11 09:41:14 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.
