Turns out this is easy to reproduce, at least for me: * Associate with a wireless network. (This step may not be necessary, but is the normal state for me.) * Click nm-applet to activate the drop-down. * Uncheck "Enable Wireless" from the nm-applet drop-down. * Click nm-applet a second time to activate the drop-down. * Note under "Wireless Networks" in the nm-applet drop-down, the message "wireless is disabled by hardware switch". * Note that "Enable Wireless" in the nm-applet drop-down is greyed out.
To re-enable wireless, I have to: * Open a terminal. * Issue: "sudo rfkill list". * Note the indexes of the Wireless LAN entries that show "Soft blocked: yes". * Issue: "sudo rfkill unblock <n>" for each value of <n> returned by the command above. * Issue: "sudo service network-manager restart". * Click nm-applet to activate the drop-down. * Check "Enable Wireless" from the nm-applet drop-down. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/977639 Title: NetworkManager erroneously reports iwlwifi as "disabled by hardware switch" Status in “network-manager” package in Ubuntu: New Bug description: I noticed last night that one of my wireless access points was not listed in nm-applet, which seemed odd given that it was only 2 metres away. I thought that disabling and re-enabling the wifi might cause a rescan, so I clicked Disable wireless networking in nm-applet. Now, nm-applet will not allow me to re-enable wireless - the section in the drop-down is greyed out, and says "wireless is disabled by hardware switch", even though the wireless card is enabled.
