Susan, According to the WifiSyslog file attached, the radio killswitch for wireless would be disabling wireless networks. You may want to look on your system whether there is a physical switch, and if it's indeed in the "enabled" position. Otherwise, laptops often have a "virtual" killswitch in the form of a key combination, such as Fn+F7 (on Dell systems). Look for an antenna drawing on function keys.
If flipping the switch or using the key combination doesn't work; please see if you can re-enable wifi with the "rfkill unblock all" command. And finally, if this doesn't last across reboots, it's possible that a kernel update has caused issues with the killswitch detection. In that case we'll need to transfer this to the 'linux' package. Please let me know! :) ** Changed in: network-manager (Ubuntu) Status: New => Incomplete ** Tags added: killswitch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787875 Title: wireless connections suddenly not seen by network-manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/787875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
