You have been subscribed to a public bug: Just after software update tonight, computer lost Wifi connection and was not seeing any Wifi Access Point.
--> I rebooted computer. Usually Wifi is always ON after reboot, it was OFF. I switch it to ON, but this did not help. --> I completely shutdown computer and switch on again. I find again after startup, Wifi is switched to OFF. I switch to ON again but computer can not see any Wifi Access Points. I checked the software update log but could not find any package related to Wifi / network manager : tail -n25 /var/log/apt/history.log Start-Date: 2017-04-28 21:30:08 Commandline: aptdaemon role='role-commit-packages' sender=':1.135' Upgrade: gir1.2-gtk-3.0:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), libnss3-nssdb:amd64 (2:3.26.2-0ubuntu0.16.04.2, 2:3.28.4-0ubuntu0.16.04.1), libapt-inst2.0:amd64 (1.2.19, 1.2.20), appstream:amd64 (0.9.4-1ubuntu2, 0.9.4-1ubuntu3), libsystemd0:amd64 (229-4ubuntu16, 229-4ubuntu17), libsystemd0:i386 (229-4ubuntu16, 229-4ubuntu17), libgtk-3-common:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), apt:amd64 (1.2.19, 1.2.20), libgtk-3-0:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), libgs9:amd64 (9.18~dfsg~0-0ubuntu2.3, 9.18~dfsg~0-0ubuntu2.4), snapd:amd64 (2.22.6, 2.24.1), snap-confine:amd64 (2.22.6, 2.24.1), libnspr4-0d:amd64 (2:4.12-0ubuntu0.16.04.1, 2:4.13.1-0ubuntu0.16.04.1), udev:amd64 (229-4ubuntu16, 229-4ubuntu17), libapt-pkg5.0:amd64 (1.2.19, 1.2.20), libnss3-1d:amd64 (2:3.26.2-0ubuntu0.16.04.2, 2:3.28.4-0ubuntu0.16.04.1), libudev1:amd64 (229-4ubuntu16, 229-4ubuntu17), libudev1:i386 (229-4ubuntu16, 229-4ubuntu17), dpkg:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2), libgtk-3-bin:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), libudev-dev:amd64 (229-4ubuntu16, 229-4ubuntu17), libgtk-3-dev:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), systemd-sysv:amd64 (229-4ubuntu16, 229-4ubuntu17), chromium-codecs-ffmpeg-extra:amd64 (57.0.2987.98-0ubuntu0.16.04.1276, 58.0.3029.81-0ubuntu0.16.04.1277), ubuntu-core-launcher:amd64 (2.22.6, 2.24.1), libpam-systemd:amd64 (229-4ubuntu16, 229-4ubuntu17), libgail-3-0:amd64 (3.18.9-1ubuntu3.2, 3.18.9-1ubuntu3.3), ghostscript:amd64 (9.18~dfsg~0-0ubuntu2.3, 9.18~dfsg~0-0ubuntu2.4), systemd:amd64 (229-4ubuntu16, 229-4ubuntu17), mysql-common:amd64 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1), apt-utils:amd64 (1.2.19, 1.2.20), ghostscript-x:amd64 (9.18~dfsg~0-0ubuntu2.3, 9.18~dfsg~0-0ubuntu2.4), libmysqlclient20:i386 (5.7.17-0ubuntu0.16.04.2, 5.7.18-0ubuntu0.16.04.1), libgs9-common:amd64 (9.18~dfsg~0-0ubuntu2.3, 9.18~dfsg~0-0ubuntu2.4), thermald:amd64 (1.5-2ubuntu3, 1.5-2ubuntu4), libnss3:amd64 (2:3.26.2-0ubuntu0.16.04.2, 2:3.28.4-0ubuntu0.16.04.1), apt-transport-https:amd64 (1.2.19, 1.2.20), libappstream3:amd64 (0.9.4-1ubuntu2, 0.9.4-1ubuntu3), xsltproc:amd64 (1.1.28-2.1, 1.1.28-2.1ubuntu0.1), libdpkg-perl:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2), libnspr4:amd64 (2:4.12-0ubuntu0.16.04.1, 2:4.13.1-0ubuntu0.16.04.1), libxslt1.1:amd64 (1.1.28-2.1, 1.1.28-2.1ubuntu0.1), libxslt1.1:i386 (1.1.28-2.1, 1.1.28-2.1ubuntu0.1), dpkg-dev:amd64 (1.18.4ubuntu1.1, 1.18.4ubuntu1.2) lspci -nn | grep 0280 0c:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02) I could not find what was the package which caused this regression so can could not revert it.
